Causal Categories in Discourse and Cognition
Causal Categories in Discourse and Cognition Categories of subjectivity in Dutch causal connectives: a usage-based analysis Ninke Stukker, Ted Sanders and Arie Jlerhagen 1. Introduction 1 Edited by Ted Sanders Eve Sweetser The meaning and the use of different types of causality markers has often been described with reference to our conceptual understanding of causality (e.g. Talmy 1988; Verhagen and Kemmer 1997; Wolff and Song 2003). We focus on causal connectives -causality markers functioning at the discourse level of linguistic structure, relating discourse segments into a coherent whole (cf. Hobbs 1979; Mann and Thompson 1988; Sanders, Spooren and Noordman 1993). In this paper, we adopt the cognitive semantic view that causality markers specifically have a categorizing function: when selecting one of the options available in a language, the speaker assigns the causal relations expressed to a specific conceptual type of causality. The meaning and use of causal connectives has recently been characterized in terms of the concept of "subjectivity" (e.g. Pander Maat and Sanders 2000, 2001; Pander Maat and Degand 2001; Pit 2003; Degand and Pander Maat 2003; Stukker 2005; Verhagen 2005; see also the contributions to the present volume). Thus, typical examples of the frequently used Dutch connectives daardoor, daarom and dus marking "forward" Cl!usality (cause precedes effect in order of presentation) can be characterized as follows: (I) Hetwas extreem koud. Daardoor waren de waterleidingen gesprongen. 'It was extremely cold. Daardoor the water pipes had burst.' (2) Het was extreem koud. Daarom :-tochten we een caje op. 'It was extremely cold. Daarom we entered a cafe.' (3) Het is onbewolkt. Dus het zal we! koud worden vandaag. 'The sky is clear. Dus it will probably be cold today.' 2009 Mouton de Gruyter Berlin · New York Daardoor is typically used for marking objective, "non-volitional" causal processes occurring in observable reality (1 ). Daarom is typically used in contexts of objective, 'volitional" causality, in which an volitional action performed in the real world ("entering a care" in (2]), is motivated by a situation presented as the cause ("the extreme cold"). Dus is typically used for marking subjective, l This chapter goes back to Stukker (2005) -- notably chapter 4. 120 Ninke Stukker, Ted Sanders and Arie ~rhagen epistemic causal relations, in which a causal relation is constructed on the illocutionary level, between a conclusion of the speaker, presented as the causal effect ("it will be cold today" in [3]), and an argument fimctioning as the causal antecedent ("the clear sky"). The idea that each one of the connectives is related to a specific conceptual model of causality will be referred to in this paper as the "categorization hypothesis". This hypothesis v11as tested in several corpus studies (e.g. Pander Maat and Sanders 1995; Pander Maat and Degand 2001; Pit 2003; Stukker 2005). These studies revealed that, indeed, the majority of connectives' natural usage contexts reflect these conceptual categories of causality more or less directly. In a minority of cases, however, the relation of connectives to their assumedly typical causality category appears to he less straightforward. Under specific circum.stances, connectives are used in contexts which are taken to belong to other connectives' causality categories. Well-knoWll examples are the usage of dus in volitional causal relations as in (4), and the usage of daarom in epistemic causal relations as in (5). (4) Het was extreem koud. Dus zochten we een cafe op. 'It was extremely cold. Dus we entered a care.' (5) llet is onbewolkt. Daarom zal het wei koud wonien vandaag. 'The sky is clear. Daarom it will probably be cold today.' Should these findings he interpreted as evidence against the categorization hypothesis? This is indeed what has been proposed by several of lhe studies mentioned above. In this paper, we follow a different line of reasoning. We re-interpret the findings from previous connective studies within a usage-based framework. The "usage-based approach to language" assumes that variation is an inherent characteristic oflangnage use, and seeks tu explain occurring patterns ofvariation with reference to more general cognitive mechaniqms (cf. Langacker !987; Bybee 1985, 2006, 2007; contributions to Barlow and Kemmer2000).ln line with this framework, we propose that an interplay of conceptual and usage factors can explain why the usage of Dutch causal connectives does not always conform to abstract detinitions that seem to he quite straightforward otherwise. Our hypothesis is that the apparent"counterexamples" are actually non-typical, or: peripheral, members (referred to in this study as "non-prototypical usages": NPU) ofthe very same conceptual category the connectives refer to in their more typical usage contexts (referred to as "prototypical usages": PU). In this paper, we focus on one specific factor c{JJJSing variation in connective use, namely: the idea that language users categorize causal relations not on the basis of" objective reality", but on the basis of their subjective construal of the situation (cf. Lan- Categories ofsubjectivity in Dutch causal connectives: a usage-based analysis 121 gacker 1987; Verhagen 2000), and on one specific factor constraining variation, namely: the prototypicality structure of semantic categories discussed above. The approach proposed here has several advantages: not only can it adequately describe the flexibility connectives show in language use, it can also explain their flexibility a,q a consequence oftheir categori7..ation function and as a consequence of more general cogoitive mechanisms governing natural language use. In section2, we discuss previous analyses ofDotch causal connectives, focusing on the usage types considered "problematic" for the categorization analysis. In section 3, we discuss theoretical assumptions underlying the usage-based perspective on language use that are relevant to our analys.is of causal connectives in terms of prototypicality structure. Section 4 presents results of an analysis of PU and NPU of daardoor, daarom and dus in a corpus of newspaper texts. 2. Patterns in cansal connective use The meaning and use of causal connectives have been deserihed with reference to the cognitively basic concepts of subjectivity and volitionality. The importance of the concept subjectivity in determining linguistic phenomena is widely atte;ied (see for example Traugott 1989, 1995; Langacker 1990; Lyons 1995; cf. discnssion in Sanders, Sanders and· Sweetser this volume). Notwithstanding terminological differences (Pit 2003; De Smet and Verstraete 2006), theorists agree that subjectivity is to a great exteut equivalent to "speaker involvement". We detine "speaker involvement" as: referring to the degree to which the present speaker is involved in the construal of the causal relation. 2 A causal relation is "subjective" if for itq interpretation reference to the speaker is needed Conversely, a linguistic element counts as "objective" if speaker involvement is absent in the interpretation of the causal relation. The results of the studies mentioned above suggest that prototypiCal usage contexts of daard<Jor, daarom and dus can he related to different categories of"objective" and "subjective causality" detined in terms of"speaker's roles": the speaker acts as a "concluder", as an volitional agent, or is absent Typical corpus examples of each category are (6)-(8) 3 : 2 This characterization is based on the definition presented by Pander Maat & Degand (2001: 214). The original definition is: "the degree to which the present speaker is implicitly involved. .. " Since SI can also be signaled explictly (with modal elements, perspective markers, etc.), we did not include the element "implicit". 3 Examples discussed are ( ~mless stated otherwise) fragments taken from the Dutch daily newspaper Trouw (year of publication: 200 l ), part ofthe corpus analyLed by Stukker (2005). 122 (6) Ninke Stukker, Ted Sanders andArie ferhagen De Boeing 747, het duurste vliegtuig dat rondvliegt, daalt steeds sneller in waarde. De afgelopen jaren is het vermogen van vliegmaatschappijen dllardoor met vele miljarden dollars verminderd. 'The Boeing 747, the most expensive plane in the air, is continuing to diminish in value rapidly. Daardoor airlines' capital has decreased by billions of dollars over the last few years.4• (7) (ln Denmark and in the Netherlands, carcasses of cows older than 30 months are tested for the cattle plague BSE). Andere Ianden zijn nag niet klaar om elk voor de s/acht aangeboden rund te onderzoeken. Zij vemietigen daarom op grote schaal dieren. 'Other countries are not yet ready for testing any individual hovine destined for consumption. Daarom they destroy animals on a large scale,' (8) (Dutch soldiers who served in Bosuia relate the high incidence of leukemia among them to frequent exposure to impoverished uranium), Maar de huidige hypothese wijt de leukemieiin aan een virus(. . . ). Het is dus denkhaar dat de soldllten die nu leukemie hebben gekregen, slachtof for zijn van iets anders dan verarmd uranium. 'But the current hypothesis attributes the leukemias to a vims. ( ... ) Dus it is conceivable that the soldiers who suffer from leukemia now, are victims of something else than impoverished uranium.' The differences hetwcen the causal relations represented above can he described as follows: Dus is typically used for marking epistemic causal relations5, in which a causal relation is constructed hetween a conclusion of the speaker presented as the causal effect ("it is conceivable that. .• " in [8]), and an argument fimctioning as the causal antecedent (the faet that the current hypothesis attributes leukemia to a virus). In epi'>lemic causal relations, the speaker functions as the source of the causal relation (it is he who relates argument and concinsjon). In other words: reference to the speaker is obligatory in order to interpret the causal relation correctly, hence the causal relation is subjective. 4 5 We focus on lhe causal relations mainly from a conceptual perspective. Therefore, lhe English glosses of our Dutch text material do not contain lireral translations; neither did we attempt to reproduce specific syntactic characteristics of the Dutch causal connectives (see for a discussion e.g. Evers-Vermeul, 2005). The category of subjective causal relations also contains "speech act" relations, in which the causal relation is constructed between a speech act and a proposition functioning as a justification ofthat speech act (Sweetser 1990); an example would be What are yau doing tonight? Because there is a good movie on). Speech act relations hardly occurred in our corpus; therefore, they will not be taken into acconnt in this paper. Categories ofsubjectivity in Dutch causal connectives; a usage-based analysis 123 This type of speaker involvement is lacking in causal relatious typically marked with daardoor and daarom. These types of relations can he seen as inherenrly "objective".6 Fragments (6) and (7) both descrihe causal relations hetween states of affairs in the observable world, having their source outside the speaker. Yet, they differ Vlith respect to the concept of volitionality. The causal relation in (7) describes an volitional act which is motivated by the situation described in the first segment Volitionality is ahsent in fragment (6) where one physical process induces another one, without intervention of a human heing. In Dutch, volitional causality is typically expressed with daarom; non-volitional causality is typically expressed with daanloor. The distinction hetween volitional and non-volitional causality is closely related to a distinction exhibited by Dutch causal auxiliary verbs, causality markers operating at the clause level of the linguistic structure (Stukker, Sanders and Verhagen 2008). The causal verbs doen and Iaten distinghuish hetween physical, "inanimate" causal processes and causal processes in wbich animate heings are involved. Just like the distinction objective-subjective, the distinction volitional-non-volitional is considered to he a cognitively important one; it reflects the conceptual model of "Naive Dualism" (Verhagen and Kemmer 1997; see also D' Anrade 1987). "Typicality", or "prototypicality" is defined in this study in terms of usage frequency. The more frequent a usage-type occurs in natural language use, the more prototypical it is taken to be (see section 3).ln the remninder of this paper, the connectives' prototypical usage contexts are referred to as "PU". As we already noted in section 1, in a minority of cases, usage-contexts of daardoor, damum and dus do not conform to the patterns described above. Under specific circumstances, co1111ectives are used in contexts which are taken to helong to other co1111ectives' causality categories. These non-prototypical usage types (which we will call "NPU'') oeeur with each of the connectives under investigation, in all of the causality categories discussed. By way of illustration, we discuss the use of dus in volitional causal contexts, assumed to he the prototypical contexts of use for daarom. Consider (9) and (10): 6 Approaches disagree on the question whether volitional causality should count as inherently subjective (see for example Pander Maat & Degand 2001 ), or as inherently objective (Stukker 2005), In this paper we assume that subjectivity is not an intrinsic characteristic of volitional causality; the fact thal some 4 'subject of consciousness" necessarily plays a role opens the way to introduce elements of subjectivity in such wntexts. The souree of subjectivity is then transferred from the speaker to an· other "subject of consciousness" ("Perspectivization": J. Sanders & Spooren 1997; specifically with reference to causal relations, see Sanders, Sanders & Sweetser this volume). 124 (9) Ninke Stuklrer, Ted Sanders and Arie W?rhagen (Bystanders ntsh to help outatt.'le Volendam pub fire.) "Ikwoon vlakbij, dus ik ben brandwondencreme gaan halen." "'I live nearby dus I ran to get burn ointment.'" (10) (Letter to the editor discussing the consequences oflowering the age limit for child adoption in the Netherlanda.) Het is allemaal heel goed te begrijpen dat de realistische adoptieouders, na de wachttijd van vele jaren, hun kindje zo snel mogelijk willen hebben. Dus kiezen ze voor een kintije uit China of een ander "snel" land. 'It is only natural that realistic adoptive parents, atler having waited for many years, want to have their child as soon as possible. Dus they opt for a child from China or from another "quick" country.' NPU of dus and daarom exhibit systematic patterning. Pander Maat and Sanders (2000) and Pander Maat and Degand (200 I) observed that volitional· causal relations marked with dus show a higher degree of subjectivity than those marked with daarom. Tbe SOC of dus-marked contexts referentially coincide with the speaker (see [9]) more often than the daarom-marked contexts do (see for example [7]; Pander Maat and Sanders 2000: 73-74; Pander Maat and Degand 2001: 239-240). In addition, volitional contexts marked with dus or daarom differ in terms of perspective configuration (Pander Maat and Sanders 2000: 71-3; for backward causal connectives, see Pit 2003; see also the chapter by Sanders et al. in the present volume). Volitional causal relations marked with dus more otlen contain "continuous speaker perspective" than those marked with daarom. Both (9) and (10) contain continnous speaker perspective. In the former, the speaker is continuously referred to by "I". In the latter fragment, the· causal relation is reported from the perspective of "they", who functions as an embedded speaker, from whose perspective the causal relation is reported. Lin~ guistic signals construing this interpretation are the occurrence of perspective markers in the cattse-segment (mental state verb "want" and evaluative element "as soon as possible", both grannnatically attJ.ibuted to the prinaary SOC "they" 7). Since this actor perspective is not explicitly "blocked" in the second segment, we assume that the perspective is continued. In fragment (7), which is representative of volitional causal relations marked with daarom, explicit indications of perspectivization are lacking. In the remainder ofthis paper, \ve Vlrill argue thatNPU ofa specific connective are adequately analyzed with reference to the causal category the connective is taken to refer to in its PU. As we will argue, a recurring pattern seems to be that 7 The tllctthat in this specific fragment the perspective of"tbey" is embedded underthe speaker's own evaluation does not make a difference for the analysis presented here. Categories ofsubjectivity in Dutch causal connectives: a usage-based analysis 125 non-typically used connectives seem to import specific elements of their PU into the foreign context, creating ambiguity in terms of causality category. In order to characterize the contrast between volitional causal relations marked with dus rather than with daarom, for example, reference to dus' more typical context of use (epistemic cattsality) is essential, no matter how subtle these differences are, or with what linguistic indications "speaker involvement" is construed. The inverse pattern seems to occur in epistemic causal relations marked with daarom. These contexts systematically contain less subjective elements than those marked with dus (Pander Maat and Sanders 2000; Pander Maat and Degand 200 I), which cao be interpreted as an indication that daarom 's epistemic NPU are in tact conceptually related to its PU of descriptive (content, objective) volitional causality. Previous studies did not analyze NPU within the objective causal domain (of daardoor and daarom), but we will see below that a similar pattern holds in these cases. 3. A usage-based interpretation of patterns in causal connective use Before we start analyzing the usage of daardoor, daarom and dus in terms of PU and NPU (see section 4), a crucial question is: How is the occurrence of NPU to be accounted for at all? We propose to do so with reference to general mechanisms of langusge use. 'The relation between linguistic knowledge and langusge nse has been studied within the "usage-based approach" to langusge (Langacker 1987, 2000; Bybee 1985, 2006; for an overview sec Barlow and Kemmer2000 and contributions to that volume). The usage-based approach assumes that variation is an inherent characteristic oflangusge use, and it seeks to explain occurring patterns of variation and stability with reference to more general coguitive mechanisms. In this section, we discuss a number of usage mechanisms which, we believe, mediate the relation between the mental representation of the conventional meaning and function of daardoor, daamm and dus, and their occurrence in language use. The first issue \ve w.mt to address is: Under the assumption that the meaning of daardoor, daarom and dus can adequately be described with reference to clearly delineated, well-defined conceptual categories of causality- how can we explain the variation occurring in contexts of natorallanguage use? We specifically focus on "subjective coru;trual" as a mechanism tJnderlying linguistic categorization (3.1) Tite seeond issue is: in view of this variation, how can we maintain the idea that daardoor, daarom and dus bave a constant meaning? We focns on prototypicality structure as a mechanism allowing for flexibility while 126 Ninke Stukl<er, Ted Sanders and Arie Verhagen maintaining the stability required for language to function as a more or less stable system of conventional symbols (3.2). Our claim will be that these mechanisms in combination explain the pattems of variation and stability observed in daardoor, daarom and dus, starting from the categorization hypothesis. 3.1. Cognitive factors producing variation in language use How can we explain that lhe meaning of connectives sometimes is, and sometimes is not completely congruent with overt signals in the linguistic contexts they are used in? The incongruence observed in Section 2 seems to be of a specific type. The NPU discussed are ambiguous with respect to causality type; they contain characteristics congruent with the causality type lhe connective is hypothesized to belong to, and at lhe same time lhey contain characteristics incongruent wilh it, but congruent wilh a difforent causality type. We propose to analyze NPU as cases of "subjective construal" of the causality category. It means lhat the same causal relation in reality may be categorized differently by different speakers, according to their particular understanding of the sitnation or lheir rhetorical purposes. This proposal is in line wilh lhe suggestion put forward in several studies of linguistic categorization that an expression's meaning is not just an objective characterization of lhe sitnation described. Equally important for linguistic semantics is how lhe speaker chooses to "construe" the sitnation and portray it for expressive purposes (Langacker [ 1990] 2002: 315, 1987; Verhagen 2007; and references cited !here). Subjective construals of categorization in terms of causality were found with causal verbs, marking canial relations at lhe clause level (Verhagen 2000; see also Verhagen 1997; Verhagen and Kemmer 1997). Thus, we can analyze lhe NPU of dus in volitional causal contexts, discussed in section 2 and repeated here, as follows. ( 11) (Bystanders rush to help out at the Volendam pub fire.) "lkwoon vtakhij, dus ik ben brandwondencreme gaan halen." '"1 live nearby dus I ran to get burn oinlment."' (12) (Letter to the editor discussing lhe consequences of lowering u'le age limit for child adoption in lhe Nelherlands.) Het is allemaal heel goed te begrijpen dllt de realistische adoptieouders, na de wachttijd van vele jaren, hun kindje zo snel mogelijk willen hebben. Dus kiezen ze voor een kindje uit China of een ander "sne/" land 'It is only natoral that realistic adoptive parents, after having waited for many years, w.mt to have their child as soon as possible. Dus they opt for a child from China or from another "quick" country.' Categories of subjectivity in Dutch causal connectives: a usage-based analysis 127 Volitional causal relations ·are inherently objective. They refer to processes which occur in observable reality. This is indicated in the contexts of (II) and (12) by the assertive speech acts, of vvhich the truth is not questioned. At the same time, the related segments of (11) and (12) contain linguistic elements construing subjectivity (speaker reference in fll], perspectivizing devices in [ 12]; see section 2), leaving the context ofuse as a whole ambiguous for causality type. The overall interpretation of the causal relation seerns to be disambiguated by the speaker's choice for a specific connective. Marking with dus in fragments (11) and (12) indicates that lhe reader is expected to construe the causal process as a case of subjective causality, despite its inherently objective character. The sn~eetive construal analysis of causal connectives proposed here is in line wilh lhe assumption lhat lhe mental representation of a linguistic utterance (in a natural context) is only partly based on lhe overt signals it contains. This assumption is accepted in various branches of linguistic study. The representntion a language user builds from a given utterance is, apart from lhe linguistic signals, a product of lhe previous discourse, hackgrom1d knowledge and inferencing (Sanders and Spooren 2001: 3; for more elaborate discussions see Fanconnier 1984; Sperber and Wilson 1995; Langacker 1987, 2000; Verhagen 1997, 2000; Radden et al. 2007).11ris inherent context dependency and underspecification of language intplies that individual usage contexts of a linguistic element may vary to lhe extent lhat lheir characteristics conform to lhe more abstract semantic representation associated wilh lhis element in language user's long term memory (Verhagen 1997). 3.2. Cognitive factors retaining stability in language representation The mechanisms discussed in Section 3 .I explain why variation may occur in lhe way abstract semantic knowledge (in our case: concerning causal connectives) is mirrored in actual language use. But in view oflhis variation, how can we maintain the idea that daardoor, daarom and dus have a eoustant meaning? Or put in more general terms: how is it possible lhat language users are able to interpret conceptual models invoked by linguistic elements in a consistent way? A common asswnption in functionally oriented branches of linguistic theory is that an individnal's linguistic system is fundamentally grounded in "usage events". This assumption has been elaberated notably wilhin what has become known as the "usage-based approach to language" (Langacker 1987, 2000; Bybee 1985, 2006; Goldberg 2005; for an overview see Barlow andKemmer2000 and contributions to that volume). According to this approach, lhe language system does not consist of rules generating grammatical instances of language 128 Ninke Stukke1; Ted Sanders andArie Verhagen use, but rather of generalizations over individual nsage events, which in tum categorize or license other usage events. In other words, according tu the usagebased approach to laugua1,-e, "granuuar is the cognitive organization of one's experience with language" (Bybee 2006: 711 ). Thus it is assumed that grammar ultimately emerges from individual USage events. This process is often compared to the more general psychological process that the occurrence of any (psychological) event leaves some kind of trace that facilitates their reoccurrence. Frequently eocountered patterns become "entreoched" in memory; acquire the statos of cognitive routine that is retrieved and applied without requiring conscious attention. Another process, which oc• curs parallel to entrenchment, is that of abstraction: the emergeoce of a structure through reinforcement of the commonality inherent in multiple experiences that difter .in some other way (Langacker 2000: 4). In this process, peculiarities of individual instances are filtered out from the representation the language nser has of the entrenched unit This process is reflected in language acquisition patterns of childreo (Barlow and Kemmer 2000: xii, see references cited). In the process of abstraction, the case of"schematization" is of particular importance for our porposes. Langacker (2000: 4) defines a "schema" as the commonality that emerges from distinct structores when one abstracts a'ovay from their points of difference by portraying them with lesser precision and specificity. TI1e phenomenon of schematization lies at the basis of language users' ability to recognize a variety of specific iustances ofuse as an iustantiation of a specific entrenched strllcture. This is the cognitive ability of categorization: recognize similarities and differences between phenomena. Or from the perspective of our problem: recognize a specific instance of use as a member of an entrenched schema. A number of factors seem to play a role in thLq process, among whicl) contextual priming (cf. discussion of the context dependency of language in Section 3.1) and the amount of overlap between the "target" and the potential categorizing structure (Langacker 2000: IS~ 17; for a more elaborate discussion see e.g. MacWhinoey 2000). Categories that emerge from linguistic experience exhibit prototype effects. "Prototypicality" refers to the well-known cognitive phenomenon that conceptual categories are not homogenous; some members of a category are better examples than others. Oranges, apples and bauanas are better examples of FRUIT than nuts and olives, which are nevertheless recognized as members of the same conceptual category (Rosch 1973) 8 • TI1e "best examples" are the category's pro8 The participants in Rosch' experiment were US college students. It is highly likely that prototypicality effects wry with regional or cultural factors (e.g, Lipka 1987; cf. discussion in Ungerer & Schmid J 996: 49-52). Categories ofsubjectivity in Dutch causal connectives: a usage-based analysis 129 totypical members; othermembtlrs vary to the degree to wl:ticll they have features in common vvith the prototype (cf. Wittgenstein 1953; Rosch 1973; Rosch and Mervis 1975). The usage-based conception oflanguage predicts that the more frequent, or: the more entrenched, contexts of use are the more prototypical members of a category, while the less frequently encountered usage contexts are more "peripheral" members belonging to the same category, related to the prototype by way of conceptual affu:tity. 9 We started this section with the question: How can we explain that language users maintain a more or less stable representation of the meaning of causal connectives, in view of the variation in usage-contexts encountered? Referriug to the usage-based theory oflanguage, \\'e may answer this quel>iion as follows. On the basis of the Iiuguistic and non-linguistic contexts of use, language users will be able to recognize the PU and NPU of causal connectives as members of one and the same category. We hypothesize that NPU of causal connectives are motivated by the phenomenon of subjective construal based on the conceptual model of sul:>jectivity. Findings reported in previous studies that seem to favor our hypothesis, are: the fact that the c.onnectives' PU are relatively frequent, and observations on the conuectives' NPU reported in previous studies (and more particularly: our interpretation of them, see Section 2). 4. Corpus analysis The usage-based perspective discussed in the previous section yields specific predictiorn concerning the patterns manifested within the variation of comlectives' contexts of use. In this section, we report a corpus analysis in which we investigate to what extent patterns of use found with daardom; daarorn and dus can he accounted for by the categorizatiou hypothesis, under the assumptiou that the "appearance" of the causality categories in language use is mediated by 9 Empirical evidence in favor of this effect of "token ftequency" is found for example in the phenomena of phonetic reduetion of high frequency words and phrases (cf. Bybee 2006, 2007), the "conserving effeet'' ~the finding that high-frequency sequences become more entrenched in their morphosyntaclic structure (e.g. Bybee 1985), and the "autonomy effecf' ~ tl1e fact that morphologically complex forms of high frequency can lose their internal structure as they become autonomous from etymologically related forms (Bybee 1985 ···· see discussion of these phenomena in Bybee 2006; see for discussion of other types of frequency effects Hasher 1984; Geeraerts, Grcndelaers & Bakema 1994; Verhagen 2000; Bybee 1985, 2007; Goldberg 2005; Schmid 2000). 130 Ninke Stukker, Ted Sanders and Arie fer hagen prototypicality effects. In Sections 4.1 and 4.2 we present our hypotheses and methods of analysis. Section 4.3 presents the resnlts of our corpus analysis. 4.1. Hypothesis 1: Frequency of use as an indication for prototypicality of PU Building on the "frequency of use reflects the cognitive entrenchment" assumption (section 3.2), our first- quantitative- hypothesis is: the connectives daardoor, daarom and dus are significantly more frequently used in usage types conforming to the categorization hypothesis (their PU). Hypothesis 1: Daardoor is prototypically used in content non-volitional relations; daarom is prototypically used in content volitional relations; dus is prototypically used in epistemic relations. Notice that this hypothesis reflects the "semasiological" perspective on word meaning. Given that a lexical items couple word forms to semantic contents, the semasiological question is: "Given linguistic item X, what meaning does it express?" This perspective is complemented by the "onomasiologial" perspective on word meaning. The onomasiological question is: "Given concept Y, what linguistic item(s) can it be expressed with?" (Geeraerts 1997: 17). Although our present research question is primarily of a semasiological nature (PU ai\d NPU are inherently semasiological concepts), both of the levels of analysis are actually relevant for understanding how the meaning and use of causal connectives relate to conceptual structure. In the final analysis, we need to know what the connectives "mean" (denote in terms of conceptual reference - the semasiological perspective) and we need to know how (with what element or elements) an articnlate conceptual category can be expressed linguistically (the onomasiological perspective). We will return to this issue in the discussion. 4.1.1. Method and operationalization In line with the usage-based assumptions presented in section 3, a usage context's degree ofprototypicality is operationalized in terms of usage-frequency: the more frequent a specific context is, the more prototypical it is taken to be. The categories of causal relations mentioned in the hypotheses will be determined making use of the "basic operation paraphrase test" of Sanders ( 1997; cf. Knott and Dale 1994). The paraphrase test makes it possible to determine the Categories of subjectivity in Dutch causal connectives: a usage-based analysis 131 relational meaning with elimination the connective's contribution to the overall interpretation of the relation. 10 The categories are operationalized as "paraphrases" (see Figure 1), explicating the relational meaning they add to the connected segments. In doing so, the type of causal relation that relates the segments can be established in an objectified and reliable way. The paraphrases are adapted from Pander Maat and Sanders, 1995 (cf. Evers-Vermenl and Stukker 2003). The paraphrases represent the connectives' hypothesized prototypical usage schemas on two aspects which have proven to be crucial for determining causality category (cf. Section 2): SOC type (implicit speaker SOC, explicit [speaker or actor] SOC, no SOC) and event type in the consequent-segment (conclusion, volitional action, nonvolitional situation). "S 1" refers to the segment containing the causal antecedent. The paraphrase itself refers to segment "S2", containing the causal effect.

Sample and procedure The frequency of use hypothesis is tested against a corpus of newspaper texts, taken from an electronic version of the Dutch national newspaper Trouw, from the year 2001. 14 In order to control for possible genre-effects ( c£ Sanders 1997), the sample was built from genres belonging to different text types. For a more detailed description of the sample, seeAppendix I. Fromeachofthe sub corpora, 50 occurrences per connective were selected. 15 Only forms functioning as markers of causal coherence relations were included, 16 and only relations holding between segments of minimally one clause were included in the sample. Occurrences were included in the sample in chronological order. The newspa- 14 Available from "Krantenbank" Factlane, (Lexis Nexis Nederland bv), a service that provides electronic access to the archives of a number of Dutch daily newspapers. 15 In order to minimize risks ofbia'i according to individual authors • styles and topic, maximally two occurrences per article were included in the corpus. 16 For an overview of other usage-types of daarom and dus, see Evers-Vermeul & Stukker, 2003; Evers-Vermeul, 2005. 134 Ninke Stukker, Ted Sanders andArie TJerhagen pers were analyzed "issue by issue" (day by day). 17 The sample was analyzed quantitatively making use of the statistical method of contrast analysis (see Appendix 2). Categories ofsubjectivity in Dutch causal connectives: a usage-based analysis usage types of a given connective. Therefore, our analysis consists of identifying general tendencies in the usage of the connectives under investigation. 4.2.2. 4.2. Hypothesis 2: Conceptual affinity ofNPU to the prototype as an indication of category membership Our second hypothesis concerns the connectives' NPU, which are expected to occur less frequently (see hypothesis 1). The degree of (non-)typicality of usage contexts is operationalized quantitatively in terms of relative frequency of use (see hypothesis 1). Non-typical contexts can thus be defined as "contexts of use, defined in terms of causality category, occurring significantly less frequently than others". On the basis of the assumptions discussed in section 3, we expect that NPU are adequately analyzed as non-typical members of the same conceptual category the connective's PU belong to. Our general expectations are that a) connectives' NPU can be analyzed as subjective coustruals of categorization, and b) the overall interpretation of NPU shows conceptual affinity to the resp. connectives' PU. The following hypotheses, specified per connective, are tested: Hypothesis 2: Given a connective a which is prototypically used in category A, and which can non-prototypically be used in category B (C, D), the nonprototypical usage of a in B (C, D) is characterized by elements 'of category A more often than when category B (C, D) is marked with connective b (c, d). 4.2.1. Method and operationalization Neither the speaker's subjective interpretation of a situation nor his rhetorical purposes are directly accessible for analysis. Therefore, subjective construals are reconstructed on the basis of the connectives' (linguistic or non-linguistic) contexts of use. It can only be hypothesized that non-typical usage types show conceptual affinity to the more typical usage types of a given connective; it cannot be known in advance what kind(s) of connection will occur; given the role of individual creativity it seems to be impossible in principle to predict all possible 17 Therefore, the distribution over text genres mirrors composition of the complete newspaper, rather than that proportional selection of all of the genres was strived at. 135 Sample and procedure The primary causality category of an NPU was determined on the basis of the linguistic context, making use of the paraphrase test described in Section 4.1; this step is performed when testing hypothesis 1. The analysis testing hypothesis 2, then, consists oflooking for demonstrable signs from the linguistic or extralinguistic contexts of use - either within the segments connected in a causal relation, or in the broader context - which motivate the categorization of the specific causal relation as the causality type associated with the connective chosen. 4.3. Results Our data largely reflect patterns found in previous corpus studies of daardoor, daarom and dus (Pander Maat and Sanders 1995, 2000; Pander Maat and Degand 2001). 4.3.1. Hypothesis 1: Usage frequency ofconnectives'PU Our first hypothesis is corroborated by the connectives in our sample (Z = 4 .30; p < .001; for a more detailed discussion of the statistical analysis see Appendix I). Figure 2 presents an overview of the relation between connectives and causality categories in the corpus from a semasiological perspective (cf. section 4.1 ). When read vertically, it answers the question: "Given connective a (b, c), what category of causality does it typically express?". Our paraphrase method revealed that the connectives' PU contexts may )>e linguistically realized with different degrees of explicitness with respect to the categories they represent. In this section we discuss the most important of the PU patterns we encountered in our corpus. Daardoor In accordance with our PU hypothesis, we found that daardoor prototypically is used in contexts of content non-volitional causality (96/100 cases). Half of the cases in our sample consist of physical processes, such as fragment (16) (discussed in section 2 as [8]): 136 Categories ofsubjectivity in Dutch causal connectives: a usage-based analysis Ninke Stukker, Ted Sanders and Arie Yerhagen CausaJity categories in conn&etives Figure 2. The relation between connectives and causality types in our sample. (16) 17 De Boeing 747, het duurste vliegtuig dat rondvliegt, daalt steeds sneller in waarde. De afgelopenjaren is hetvermogen van vliegmaatschappijen daardMr met vele miljarden dollars verminderd. 'The Boeing 747, the most expensive plane in the air, is continuing tO diminish in value rapidly. Daardoor airlines' capital has decreased by millions of dollars over the last few years.' The other balf of the non-volitional daardoor contexts concerned cansal processes with animate beings as a locus of effect, an example is (17). (17) Magje een onderzoek van vorige week geloven, dan speelt in Amsterdam een derde van de kinderen tussen zeven en negen nooit buiten.· [. .. J Daardoor leren ze niet goed om te gaan met andere kinderen en dat is weer slecht voor later, als ze voorldurend nieuwe mensen leren kennen. 'If you are to believe a study from last \veek, a third of the children in Amsterdam between the ages of seven and nine never play outside. Daardoor they do not learn to interact with other children: that bas a negative effect later on when they continue to meet new people.' 17 Two of dus' contexts of use and three of daarom's contexts of use in the sample were categorized as speech act causality. Because of the extremely low frequency, these cases were not further taken into account. For this reason, the sums total of daarom and dus in figure 3 do not add up to I 00. The speech act cases were discarded 137 Despite anima~'}' of the locus of effect, (17) is not a case of volitional causality; the paraphrase "The situation in SJ is a motivation for the following action: S2" does not adequately reflect the purport of the relation. Since (17) reports on an investigation conducted by other persons than the writer of the fragment, categorization as an epistemic causal relation is not very likely either. This is reflected in the fact that the paraphrase for epistemic causality "The situation in Sf is an argument for the following conclusion: SZ" does not fit this context either. The paraphrase for non-volitional causality "The situation in Sl leads to the following situation: S2 " is the only one fitting this context adequately. This ean be explained by the fact that "they" cannot be analyzed as a subject of consciousness. "Learn to interact with other children" is a mental process that can only take place in an animate being, but occurrence of the process is not dependent on the experiencer's intentions of doing so. Daardoor may also occur in non-volitional relations containing an action predicate in S2, as in fragment (18). ( 18) De schaatser Frans de Ronde omschreefde Jaap Edenbaan als een grote kattebak. "Overallag zand. Dao.rt/Qor schaatsten velen met bramen op hun ijzers. [. .. ]". 'The skater Frans de Ronde defined the Jaap Eden rink as a big kitty litter bin. ''There was sand everywhere. Daardoor many skaters skated with scratches on their blades."' Interestingly, in spite of the presence of the inherently volitional action in the consequence segment, the paraphrase of volitional causal relations "The situation in Sl was a motivation for the following action: S2" does not fit very well. The adequate interpretation of this relation is not that the fact that "sand was all over the skating rink" led to the volitional action of "skating of many", but that the situation depicted in S 1 led to the unvolitional situation of "many skaters skating with scratches on their blades". Note that the deviant instantiations ofdaardoor's PU non-volitional causality we discuss here, and other connectives' PU we discuss in this section, are not to be classified as NPU. The reconstructions indicate that classification in accordance with the connective's PU causality type yields the most plausible interpretation. Daarom the present psper for reasons of space. See for a discussion of speech act causality As noted in previous studies (cf: Pander Maat and Sanders 2000; Pander Maat and Degand 2001), daarom is the most "generalist" of dte three connectives analyzed in this study. It is the only connective that is conventionally used in Sanders et al., this volwne). all of the categories disfinguished Still, in accordance 1Nith our PU hypothesis, from statistical analysis. We did not discuss the category of speech act causality in 138 Ninke Stukker, Ted Sanders and Arie Verhagen daarom has a statistically significant preference for volitional causal relations (50/100). The majority of these contexts contain an overtly expressed action iu S2. An example of this pattern is (19), discussed in section 2 as (9). (19) (In Denmark and in the Netherlands, carcasses of cows older than 30 months are tested for the cattle plague BSE). Andere Ianden zijn nog niet klaar om elk voor de slacht aangeboden rnnd te onderzoeken. Zij vemietigen daarom op grate schaal dieren. 'Other countries are not yet ready for testing any individual bovine destined for consumption. Daarom they destroy animals on a large scale.' However, volitionality of the causal relation need not be explicitly specified with an action predicate. The paraphrase test identified volitional causal relations without overtly expressed actor SOC's. As an example, consider (20), in which the inherent volitionality ofthe causal relation is "hidden" in an agentless passive construction. (20) Toen Napoleon ook Holland in bezit kreeg, was de vaart ineens niet meer nodig. De Noordervaart is daarom nooit verder gegraven dan tot Beringe. 'Once Napoleon controlled Holland as well, the waterway was no longer necessary. Daarom the Great Northern Canal was never dug any further than Beringe.' Some contexts in our sample even contained state predicates which appeared to be relevant in the interpretation of the relation as "result of an action". These· cases were analyzed as volitional causal relations. An example is (21 ). (21) Microsoft-oprichter Bill Gates waagde zichzelf als eerste aan het spel tijdens een computerbeurs in gokparadijs Las Jlegas. "Wlj wilden iets bouwen dat een doorbraak voor computerfreaks is '', omschrijft de · voormalige topman Microsofts ambities. Het zwart gekleurde apparaat heeft daarom vier aansluitingen voor besturingsknuppels meegekregen, waar de gangbare "gameboys " er maar twee hebben. 'Microsoft's founder Bill Gates was the first to try the game during a computer conference in gambler's paradise Las Vegas. "We wanted to build something that would be a breakthrough for computer freaks" explains Microsoft's ex- top executive. Daarom the black colored machine has been provided with four conoections for game pads, while the current "gameboys" have ouly two.' Categories ofsubjectivity in Dutch causal connectives: a usage-based analysis 139 The perfect heeft meegekregen in (21) (literally: 'has received') suggests an act of transfer, including an volitional actor (hence the translation 'has been provided with'). Thus both in (20) and in (21), the paraphrase for volitional causal relations, "The situation in SJ was a motivation for the following action: S2 " is the only one that fits these contexts adequately. Dus Dus is prototypically used in the category of epistemic causality (761100). This is in accordance with our PU hypothesis. A typical example of this category is (22), discussed in section 2 as (10). (22) (Dutch soldiers who served in Bosnia relate the higb incidence of leukemia among them to frequent exposure to impoverished uranium). Maar de huidige hypothese wijt de leukemieiin aan een virus ( .. ). Het is dus denkbaar dat de so/daten die nu leukemie hebben gekregen, slachtoffer zi}n van iets anders dan verarmd uranium. 'But the current hypothesis attributes the leukemias to a virus. (... ) Dus it is conceivable that the soldiers who suffer from leukemia now, are victims of something else than impoverished urauium.' Epistemic causal relations are, in a large majority of cases, easily recognized by way of subjective elements (signs of "self-expression" of a SOC: evaluations, modal elements, etc., cf. Langacker 1990; J. Sanders and Spooren 1997; Pit 2003). But sometimes, the intended epistemic interpretation is linguistically "underspecified". Yet, the paraphrase of epistemic causality "The situation in Sl is an argument for the following conclusion: S2" is the only one that fits these contexts adequately. An example is (23). (23) (A "pavese" is a weapon shield) Twee eeuwen lang, tussen 1300 and 1500, zijn paveses overal in Europa in gebrnik geweest, dus ook in Nederlandse legers. 'During two centuries, between 1300 and 1500, paveses were used everywhere in Europe, dus in Dutch armies as well.' Underspecified epistemic causal relations concern almost without exception instances of "noncausal epistemic relations" in which either the real-world causality has a different direction than the epistemic one (so-called "abductive" causality 19 ), or real world causality is not relevant at all, as in the case of (23), 19 An example from our corpus is "Dan moet je eerst uitvinden van welk station je vertrekt. Rouaan ligt ten westen van Parijs. Dus het Noordstation, waar je in de 140 Ninke Stukker, Ted Sanders and Arie ferhagen an instance of assumption based reasoning ( cf. Pander Maat and Degand 2001: 221-224). Noncausal epistemic relations can be identified making use of the paraphrase test. A non-standard lingnistic construal of an epistemic causal relation is (24). Judging from form characteristics, the relation between S 1 and S2 can be interpreted both as a motivation for the (genuine) question "why shouldn't Braakhekke sing on stage?" (in which case it should have been categorized as speech act causality, cf. Sweetser 1990; see also Sanders et al. this volume), and as giving an argument for the conclusion that is formulated as a rhetorical question "Braakhekke should sing on stage as well", which leads to categorization as an epistemic causal relation. The latter interpretation seems to be the more adequate one in this context, where the cook justifies his involvement with theatre. This is corroborated by the fact that the paraphrase for epistemic causality "The situation in SJ is an argument for the following conclusion: S2" adequately reflects the purport of the relation in (24). (24) (Television chef Braakhekke also appears on stage these days) Is Braakhekke wellicht een aandachtsjunk, wil de interviewer weten. "Neeeee ", kaatst de lange uithaal tot over het Leidseplein. Braakhekke "likt aileen graag aan het theater en zingt altijd onder het koken, dus: waarom niet op het toneel?" 'The interviewer wonders whether Braakhekke is perhaps an attention junkie?, "Noooo", resounds his answer across the Leidseplein. Braakhekke "only likes to lick the theatre and sings while he is cooking, dus: Why not on stage?"' Conclusion from the PU analysis On the basis of the "frequency reflects entrenchment assumption", then, we interpret the results of our PU analysis as an indication that the usage contexts conforming to the categorization hypothesis are more entrenched in the language user's semantic knowledge than the usage contexts which do not conform to the categorization hypothesis. buurt Belgische frieten kunt kopen?" Then first you have to find out from which station you'll be leaving. Rauen lies west ofParis. "Dus "the North station, in which surroundings you can buy Belgien fries? Categories ofsubjectivity in Dutch causal connectives: a usage-based analysis 4.3.2. 141 Hypothesis 2: Conceptual affinity of connectives' NPU to their PU Our second hypothesis concerns the non-typical contexts of use (NPU) of daardoor, daarom and dus. We hypothesized (section 4.2) that the connectives'NPU reflect characteristics of their PU, to such an extent that the NPU can be analyzed as peripheral members from the same semantic category the connectives' PU belong to. In this section, we describe NPU patterns we found in our sample. Per pattern we discuss one representative example. We describe in what way the NPU is conceptually related to the connective's PU, and also how the NPU pattern diverges from the same causality category marked with one of the other cmmectives. Daardoor Daardoor is typically used to mark non-volitional causal relations (see section 4.3.1 ). In a small minority of cases in our sample (4/100), it is used to mark volitional causal relations. An example is (25): (25) De Chinezen krijgen dit jaar vee[ meer vrije dagen. De regering hoopt dat de bevolking daardoor meer spaargeld gaat uitgeven om de groei van de economie op peil te houden. 'The Chinese get more vacation days this year. The government hopes that daardoor the populace will spend more of its savings to keep the economy growing.' The causal relation in (25) is constructed between the first sentence the complement clause of the second sentence. The fragment is taken from an article which discusses a characteristic of the economic climate in China, namely that the Chinese people tend to save all their money instead of spending it and thus stimulate economic activity. The causal relation in (25) is best explicated with the paraphrase for voliti<,mal causality, "The situation in SJ is a motivation for the following action: S2 ". The paraphrase for non-volitional causality, "The situation in SJ leads to the following situation: S2" doesn't seem to reflect the purport of (25) adequately. However, in accordance with our second hypothesis, daardoor-marked volitional causal contexts systematically exhibit conceptual affinity to daardoor's PU on the aspect of the relation's "locus of effect". They differ from daarom and dus marked volitional contexts with respect to degree of intentionality of this locus of effect. 142 Ninke Stukker, Ted Sanders and Arie Verhagen In the case of (25), the locus of effect "the populace", is ambiguous with respect to SOC-hood. On the one hand, the predicate "spend" in S2 is inherently intentional. On these grounds, we would have to interpret (25) as containing an actor SOC. On the other hand, "spend" is presented as instantiating systematic patterns. The measure of allotting the people more holidays is prompted by an (assumed) social law: "holidays are spent shopping" or "the more time off, the more shopping is done". A linguistic indication in favor of this non-volitional interpretation is that the causal relation is strongly presented from the perspective of Chinese government. Although a "normal" intentional causal interpretation of the situation reported is certainly conceivable on a conceptual level (Chioese people consider more holidays a reason for going shopping more frequently), the present wording favors an interpretation from the perspective of the government. The first indication of this is the embedding of the cause-segment in a matrix sentence that conveys a mental state of the government. The next indication is located in the second part of the effect-segment, a goal presented internally in the sentence, namely, the action of spending. It is improbable that "to keep the economy growing" specifies the goal that "the populace" has for "spending", as the construction of the sentence suggests. Most probably, this element should be understood as a motivation for introducing the measure from the perspective of the government. This is possibly why the volitional causal paraphrase "The situation in Sl is a motivation for the follawing action: S2" fits this context well, while at the same time the intentions of the aetna! intentional agents are not very relevant in interpreting the situation. Similar elements indicating "restricted intentionality" can be identified in the other volitional contexts from daardoor, but they are absent in any of !he daarom- or dus-marked volitional relations (see table I; cf. the examples of volitional daarom discussed in section 4.3.1 and the volitional dus example in [31] discussed below). Although the effect-denoting segments of the daardoormarked cases contain an action predicate and an animate locus of effect, these are not to be construed as a genuinely intentionally acting "SOC''s (cf. Section 2). It is highly "unlikely that the loci of effect in these cases consciously interpreted the situation presented in the cause-segment as a valid reason for performing the action depicted in the effect-segment; their "intentionality'' seems to be of a restricted kind. These observations indicate that daardoor-marked cases show a conceptual relatedness to daardoor's PU, non-volitional causal relations, where human intentionality does not play a relevant role. 20 20 Note that fragment (25), just like the three other volitional contexts of daardoor, differ from daardoor-marked fragments with "non-volitional action predicates", one ofthe patterns instantiating daardoor's PU (cf. [18], discussed in section 4.3.1 ). In the latter case, ambiguity of the intentional aspect in the relation is solved at Categories of subjectivity in Dutch causal connectives: a usage-based analysis 143 Table 1.

It is also the only connective that has NPU in two different causality types, namely non-volitional causality (16/100) and epistemic causality (311100). We start our discussion with the latter type, an example is (26). (26) (Selecting tall players for volleyball increases chances of international success) "Nederland heet een langvolk te zijn, maar via de clubs vinden we de lange talenten niet. Ze !open we[ op straat rand; vaak geftustreerd al vroeg met sport gestopt, omdat hun motoriek tijdens de eerste puberjaren achterloopt bij die van ldeinere leefiijdsgenootjes. Daarom moeten wij zelfnaar de scholen gaan om ze te vinden en om ze te overtuigen dat ze juist door volleybal meer eigenwaarde kunnen krijgen." "'The Dutch are supposed to be a tall people, but we can't find the tall talents through the clubs. They're walking around on the streets; often already long frustrated and having given up the sport, because their motor skills are not that of their smaller peers when they're teenagers. Daarom we have to go to schools ourselves to find them and convince them they'd be greatly appreciated in volleyball."' Fragment (26) contains an intentional action predicate in S2, but this predicate is embedded under a modal verb. Therefore, the paraphrase for volitional causality, which is daarom's PU, "The situation in Sl is a motivation for the following action: S2" does not fit this context adequately. The paraphrase for epistemic causality ''The situation in Sl is an argument for the following conclusion: S2 " by contrast, does. Epistemic causality is distinguished from other types by its inherent high degree of speaker involvement. The source ofthe causal the segmental level (see discussion in 4.3.1 ), while ambiguity of intentionality in volitional relations with daardoor, such as (25), occurs at the relational level. 144 Ninke Stukker, Ted Sanders and Arie Verhagen relation is by default the speaker2 1 , relating an argument to a conclusion in ongoing discourse. This characteristic is lacking in daarom's PU volitional causality. Our hypothesis therefore predicts that epistemic causal relations marked with daarom are relatively less subjective than the dus-marked ones. We expect that the contexts of use of epistemic daarom relatively more often contain characteristics associated with daarom's PU: causality. In our data, we found two patterns corroborating this expectation. The first indication concerns modality type. The category ofepistemic causality arguably contains two different types of conclusions. The first involves "real" epistemic modality: conclusions regarding the probability of the truth of proposition P. An example of this type is S2 of (27), discussed as a PU context of dus in section 4.3.1 (22), and repeated here as (27). Categories of subjectivity in Dutch causal connectives: a usage-based analysis 145 but dus appears to prefer "real epistemic" modality, while daarom appears to be distributed over the two types rather evenly. Deontic modality with dus is exceptional. Table 2 presents an overview. Table 2. Modality type in dus and daarom. Epistemic modality Deontic modality Daarom 14 12 Total 2621 Dus 70 6 76 Total 84 18 102 We found an asymmetry in distribution of dus and daarom over modality types (Z = 3.97; p < .001) which is in line with our expectation concerning their differences. Both connectives can express both of the modality types, Both in epistemic and in deontic modality, the speaker expresses an attitnde towards the proposition, which classifies both types as subjective. However, deantic and epistemic modality differ in terms of degree of subjectivity. Deontic modality (or: agent-oriented modality [Bybee et al. 1994], root modality [J. Sanders 1994]) reports the existence of internal and external conditions on an agent with respect to the completion of the action expressed in the main predicate. As a report, the agent-oriented modality is part of the propositional content of the clause (Bybee et al. 1994: 177). Deontic modality refers to a situation in observable reality, and is not uniquely linked to the speaker as a source ofjudgment of the sitnation depicted. Epistemic modality, on the contrary, is typically concerned with the "truth" of a proposition in which the speaker is a primary source of responsibility of the epistemic judgment (cf. Traugott 1989; Sweetser 1990; Bybee et al. 1994). The relatively large proportion of deontic contextswhich count as relatively objective contexts, despite its inherent subjectivity marked with daarom can be interpreted as an indication that daarom 's epistemic causal NPU exhibit conceptual affinity to daarom's PU of objective, volitional causality. A second pattern distinguishing epistemic daarom from epistemic dus concerns the "information statns" of the segment functioning as the conclusion in the epistemic relation. Whereas in dus-marked epistemic relations the conclusion is always performed in the actual discourse situation, in epistemic contexts marked with daarom, the conclusion may concern "given information". An example of an epistemic relation with a conclusion performed in aetna! discourse is (27) above. An example of an epistemic relation with a "given" conclusion is (28): 21 This may also be an embedded speaker, to whom the actual speaker "lends" perspective (cf. J. Sanders 1994; see also discussion of this type of fragments in Sanders et a!. this volume). 21 Five of the epistemic daarom- fragments in the corpus could not be classified as epistemic or deontic modality. This is why the sum total in this analysis amounts to only 26. (27) (Dutch soldiers who served in Bosnia relate the high incidence of leukemia among them to frequent exposure to impoverished uranium). Maar de huidige hypothese wijt de leukemieen aan een virus ( .. ). Het is dus denkbaar dat de so/daten die nu leukemie hebben gekregen, slachtoffer zijn van iets anders dan verarmd uranium. 'But the current hypothesis attributes the leukemias to a virus. ( ... ) Dus it is conceivable that the soldiers who suffer from leukemia now, are victims of something else than impoverished uranium.' The other type involves so-called deontic modality (conclusions about the desirability of some course of action expressed in P (Pander Maat and Sanders 2000: 74; cf. Sweetser 1990). An example of a causal coherence relation expressing deontic modality in S2 is (26) above. Following Sweetser (1990:49) "deontic" and "epistemic" modality are defined as follows: Modality type Definition Deontic modality real-world obligation, permission or ability Epistemic modality necessity, probability or possibility Figure 3. Distinction between deontic and epistemic modality (Sweetser 1990). 146 (28) Ninke Stukker, Ted Sanders and Arie V<!rhagen "Maar bij emstige brandwonden is het hele lichaam ziek", zegt Hermans.

Categories ofsubjectivity in Dutch causal connectives: a usage-based analysis for this conclusion are. 23 Table 3 summarizes the distribution of"performativity of the conclusion" over epistemic causal relations marked with dus or dilarom 24 Table 3. Distribution of"perfonnativity of the conclusion" over epistemic causal relations marked with dus or daarom. Conclusion performed Fragment (28) is taken from a "backgrouod" article which discusses the question whether the capacity of care for burn injuries in the Netherlaods is to be extended or not. The interviewee, Professor Hermans, argues against this proposition. The cause-part of the relation in (28) must be interpreted as an argument for the conclusion in the effect-part, stating that care for burn victims is complicated; the paraphrase for epistemic causality "The situation in SJ is an argument for the following conclusion: S2 " conveys this interpretation. best. However, this is not the only aspect cornrnuoicated in this fragment. Judging from the referential expression zo (roughly translated as 'this') preceding the evaluative expression ingewikkeld ('complicated'), this evaluation is not new. As a matter of fact, Hermans is quoted twice in the article. Fragment (28) represents the second quote. Fragment (29) precedes the fragment cited in (28) aod contains the first quote: (29) "Het gaat niet om het personeel. VOor deze zorg zijn zeer gespecialiseerde verpleegkundigen, internisten, anesthesisten en chirurgen nodig. Als daar meer van komen, hebben ze ieder te weinig werk om routine op te bouwen. En dat kan riskant zijn." "'The arnouot of personnel is not relevaot. For this type of patient" care, highly specialized nurses, internists, aoaesthesists, and surgeons are needed. If their number increases, individually, they won't be able to practice their skills to a sufficient extent. That may be daogerous."' The proposition that "the care for these patients is (... ) complicated" is conceptUally present immediately after this first quote, as ao inference from Hermans' statement that "for this kind of patient care, highly specialized ... are needed". Yet, the inferred proposition is stated explictly in the second quote, aod the proposition innnediately preceding it firoctions as a justification for stating this proposition. Thus, the conclusion segment of the causal relation in (28) is ambiguous for information status. The information conveyed in the conclusion part itselfis not entirely "new", but its status as a conclusion, and the justification 147 Daarom 24 Conc~usion given Total 7 31 Dus 76 0 76 Total 100 7 107 23 This ambiguity of information status of the relation as a whole renders "nonperformative conclusion relations" somewhat ambiguous for causality type as well, namely between epistemic and non-volitional causality. Since the paraphrase test explictly addresses the "informational surplus" of a causal relation (cf. Sanders, Spooren & Noordman 1993) we chose to categorize this type as epistemic. Whether categorization of "non-performative conclusion relations" as epistemic causal relations is actually the most adequate analysis remains a matter of debate (see also Sanders & Spooren 2007, who claim that the inference of"new" knowledge is a distinguishing feature ofepistemic relations). Categorization of these cases as content non-volitional would not alter the overall picture of the analysis of distribution of daardoor, daarom and dus presented in this paper (Z=I.28; p<.001; cp. the values of our present analysis [Z~4.30; p<.001] reported in section 4.3.2). 24 Epistemic causality with a "given conclusion'' marked with daarom must be distinguished from the marking of"given information" status with dus in the function of discourse marker of information management (cf. Schiffrin 1987). An example is Op het moment dat de eerste burger zich openlijk aforoeg wie de openin?Jshandeling wilde verrichten, ging een groat aantal vingers de Iucht in. Het werd dus Hilde Zaer. 'At the moment the mayor explicitly asked who wanted to do the opening ceremony, many people raised their hands. Hilde Zoer became '~en" the person to do it.' In this fragment dus does not function as a connective marking a causal coherence relation, but as a marker of information status, signaling how the information within its scope is to be interpreted with respect to the rest of the information presented in the text. See for a more elaborate discussion Evers-Verrneul & Stukker (2003); Evers-Verrneul (2005:chapter 7).

(30) (Chess-player Kasparov shows disrespect with regard to his compatriot and fellow chess-player Kramnik.) Kramnik zou iemand zijn. die nooit of te nimmer aanvalt en daarom zo zelden verliest. 'Kramnik was supposed to be a person who never ever attacks and daarom thus seldomly loses a game.' The causal relation in (30) is coustructed hetween the two complement clauses. The situation described in S2 "thus seldomly loses a game" carmot be interpreted aB an volitional action. 1herefore, the paraphrase for volitional causal relations "The situation in SI is a motivation for the following action: S2" does not explicate the causal relation in (30) adequately. The paraphrase fornon-volitional causal relations "The situation in Slleads to the following situation: S2 ",docs. The defining characteristic of non-volitional relations is that the source of the causal process is rwt located in an volitionally acting human being. In other words, it does not contain an SOC. The locus of effect is either au inanimate entity or an animate being construed as an "experiencer" (non-agent; e.g. Frawley 1992; Croft 1998). On the grounds of our second hypothesis, we expect that non-volitional relations marked with daarom contain characteristics ofdnarom's PU volitional causality, containing an actor SOC. We found one pattern corroborating our expectations, namely that nonvolitional relations marked with daarom have a numerical preference for animate loci of effect "This preference is lacking in non-volitional relations marked with daardoor (cf. the discussion of PU daardoor in section 4.3.1) (Z = 2.22; p .02).25 Table 4 presents an overview.

Dus NPU contexts of dus concern volitional causal relations (22/100). An example is (31) -discussed in section 2, and repeated here. (31) (Bystanders rush to help out at the Volendam pub fire.) "Ikwoon vlakbij, dus ik ben brandwondencreme gaan halen." '"I live nearby dus I ran to get burn ointment."' The paraphrase for epistemic causal relations The situation in Sl is an argumentfor the following conclusion: "S2"- which reflects dus' PU- does not fit this context The paraphrase for volitional causal relations ·'The situntion in Sl was a motivation for the following action: S2 ",does. Volitional causal relations marked with dus systematically exhibit a conceptual affinity to its PU of epistemic causality. In the majority of dus-marked cases, the SOC seems to be not only relevant as an 'volitional agenf' - which is the defining characteristic of volitional causal relations -but also as a subjective agent "justi:tying" tbe particular course of action chosen. This aspect may cause a higher level of speaker involvement in the causal relation, aud in this respect dus' NPU of volitional causality reflects a defining characteristic of its PU of epistemic causality. In this respect, volitional causal relations marked with daardoor or daarom seem to form the mirror image from the patterns found with dus. A pattern which we consider indicative for this tendency concerns perspective configuration. In volitional causal relations, the cause-part of the relation may or may not be presented from the perspective of the SOC, from v.-hose perspective the effect-part of the relation is presented by default. Pander Maat and Sanders (2000) found that dus-marked volitional causal relations t<:nd to be present<:d from "continuous actor perspective" more often than daarom-marked ones. The causal relation in (31) is presented from a continuous actor perspective, which is signaled in this fragment by the quotation marks, and by continuous reference to the speaker with "l" (see discussion of this example in section 2). As an effect of this explicitly marked continuous perspective, the causal relation is construed as containing a high level of speaker involvement; in particular, we tend to interpret the cause-part of the relation not as a mere description of a motivation for the action performed but rather as a justification of that action. By way of e<:>ntrast, consider fragment (32) (discussed in section 4.3.1 as au example of daarom's PU context of volitional causality) which contains an 150 Ninke Stukker, Ted Sanders and Arie Verhagen Categories ofsubjectivity in Dutch causal connectives: a usage-based analysis example of a volitional causal relation with non-continuous perspective configuration.

Table 5. 151 Summary and interpretation ofthe results The starting point of our paper was the assumption that causal connectives are directly related to conceptual categories of causality, and that causal connectives function as categorization devices. When selecting one of the options available in a language, the speaker assigns the causal relations expressed to a specific conceptual type of causality. Findings from previous studies seemed to contradict this categorization hypothesis. Corpus analyses had revealed that a 1-to1-relation between categories and patterns of connective use does not exist. In this paper, we reinterpreted these finding for three frl'quently used Dutch causal connectives: daardoor, daarom and dus, within a usage-based framework. The ''usage-based approach to language" assumes that variation is an inherent characteristic oflanguage use, and it seeks to explain occurring patterns of variation with reference to more general cognitive mechanisms. Our re-analysis suggests that the patterns of use exhibited by these connectives can adequately be described and explained with reference to the well-known cognitive phenomenon of"prototypicality structure". On the whole, our data re- !52 Ninke Stukker, Ted Sanders and Arie ferhagen veal two sources of evidence for this hypothesis. First, in a large majority of cases, the connectives under investigation occur more in contexts of use which directly reflect the relevant conceptual categories. Within a usage-based framework, this can be interpreted as an indication that these types of connective use are relatively more enteenched in the language user's knowledge concerning causal connectives. The more entrenched usage types can be thought of as a semantic category's prototypical center, which we referred to as the connectives' prototypical usages (PU). Second, the usage contexts which do not directly reflect the relevant categories, systematically exhibit conceptual affinity to their prototypical usage schemas. We referred to these as the connectives' non-prototypical usages (NPU). The conceptual affinity of NPU with PU could systematically be described witl1 reference to the conceptual model of subjectivity, which was shown to govern categorization of the connectives' PU. We interpreted these findings as an indication that the variety ofusage types per connective belong to one and the same semantic category. The usage-based approach to language assumes that the levels of language structure, conceptual structure and language use interact. What does this interaction look like for the Dutch forward causal connectives we investigated in this paper? Our findings suggest that it can be schematized as in figure 5. Categories of subjectivity in Dutch causal connectives: a usage-based analysis !53 edge and 1anguage use concerning the connectives daardoor, daarom anddus. ii Linguistic category; 411 Conceptual category; C Domain of usage. while dam-om and daardoor are typically used in contexts of objective, content causality: Within the domain of obj e<:tive causality, daarom and daardoor distinguish between volitional and non-volitional causality. This distinction is closely related to the conceptoal model of naive dualism - which reflects the conceptually important distinction between volitional animate beings and inanimate entities (Verhagen and Kemmer 1997; Stukker, Sanders and Verhagen 2008). The assumption that a direct relation exists between these conceptual categories of causality and the linguistic categories of daardam; daarom and dus, is symbolized in Figure 5 by two sets of circles: Tbe upper level represents the level oflinguistic knowledge; the lower level represents the level of conceptual knowledge. The relative position of the circles symbolizes their mutoal connection: The linguistic categmies invariably reflect the conceptual categories. The "bold" lines symbolize our ;mggestion that the linguistic categories of causal connectives and the conceptual categories of causality they refer to, are invariable, clearly delineated, categories. Figure 5 also symbolizes the finding that the usage of the cmmectives is not restricted to their prototypical centers - all of the circles have extensions into other conceptual domains. This is indicated by the oval forms. Their form and relation to the meaning circles symbolize our suggestion that the extended usages belong to the very same conceptual category as the respective connectives' prototypes - creating an ambiguous construal in terms of causality categories given that other linguistic or contextual elements indicate another category of causality- but at the same time, that the possibility of extension is restricted by the respective prototypes. Thus, we suggest that the variability of connective use observed in corpora is to be accounted for at the level of language use itself, and not directly at the level of linguistic and conceptual categories, even though the categories are based on experience in nsage. Since this variability is. rooted in contextual factors, specifically .in the speaker's subjective interpretation of a given situation and his rhetorical purposes, we cannot, as a matter of principle, predict the forms the cmmectives' NPU may takeP This inherent variability at the level of connective use is symbolized in Figure 5 by the dotted lines. 1be asymmetric forms of the ovals representing the level of language use, however, represent our finding that the relative frequency of extensions from the prototypical centers vary per connective: NPU of daarom and dus into their respective conceptual domains occur more frequently than NPU of daardoor. The connectives' PU reflect well-known and widely attested conceptual categories. A first conceptual distinction which is reflected in the usage of the connectives under investigation is the distinction between objective and snbjective causality: dus is typically used in contexts of subjective, epistemic causality, 27 We can, however, make predictions. about the interpretation of a connective's NPU, which may in turn be tested. This was the point of sections 4.2 and 4.3. Daardoor Daarom Dus Objective Objective Subjective Non-volitional Volitional Epistemic Causality Causality Causality Figure 5.

Discussion of the results from a "categorization" perspective Maat and Sanders 2000, 2001; Pander Maat and Degand 2001). We agree that this conceptual connection exists, but on the other hand, our results suggest that the conceptual differences between volitional causality and epistemic causality may be more fundamental than has been suggested in the subjectivity scale account of causal connectives. A systematic difference concerns the SOC's roles and SOC distance to the speaker. In volitional causal relations, the SOC is part of the causally related propositions by definition, as the agentive subject of the action predicate expressed in the relation's consequent segment. Thus, in volitional relations, a certain distance between speaker and SOC is the default. In epistemic relations on the other hand, the SOC is not part of the causally related propositions. In typical cases, speaker and (extra-propositional) SOC coincide. Typical cases of epistemic causal relations concern relations constructed by a speaker SOC who is not explicitly referred to (that is, to its role as a SOC) in the related propositions. An example is The light in the neighbours living room are out. So they are not at home. In less typical cases (at least, in newspaper text) the actual speaker reports epistemic processes constructed by other persons. An example would be Harry saw that the lights in his neighbours living room were out. He concluded that they were not at home (examples taken from Pander Maat and Sanders 2000: 67). But even in these cases, the explicitly mentioned concluder SOC is not part of the causally related propositions. The matrix sentence He concluded that functions as a mental space builder, indicating that the epistemic relation's "illocutionary force" is to be located in an embedded speaker (indicated by the matrix sentence) and not in the present speaker (see for a discussion of mental space configurations like these Sanders et al.in the present volume. See also Verhagen 2005: chapter 3). This distinction coincides with a fundamental distinction proposed in many theories on subjectivity, e.g. Langacker's (1987, 1990) distinction between subject ("ground") and object of conceptualization, and his defiuition of subjectivity in terms of presence or absence of the "ground" in the linguistic construal of a particular situation; cf. also Traugott's definition of subjectification as "meanings grounded in the speaker's subjective attitude to or a belief about what is said" (Traugott and Konig 1991: 189; for a more elaborate discussion of various definitions of subjectivity, see the contribution of Sanders eta!. to this volume). The results of the usage-based corpus analysis we presented in Section 4 suggest that it is exactly this distinction between propositional and nonpropositional SOC that is mirrored in the contrasts between connectives28 . If Some previous studies of causal connective use have suggested that their meaning must be characterized as positions on a scale of subjectivity rather than as conceptual categories, but we have argued that the phenomena involved can actually be integrated in a natural way in a usage based approach to categorization (cf. discussion in Section 3). This is not to deny the relevance of the observations and analyses adduced in favor of the scalar approach - on the contrary. Below, we discuss how a categorization perspective leads to a different interpretation of these similar findings, offering alternative explanations of usage facts that have been observed before, and sometimes suggesting new explanations for facts that have been observed previously, but were left unexplained. Onr findings suggest that~ while contexts of use of a causal connective may differ to the extent that they reflect characteristics of the causality category it is prototypically associated with - the connectives' function remains constant over the complete range of contexts it is used in. We suggested that connectives' PU and NPU belong to one and the same semantic category, and this category is adequately characterized with reference to conceptual categories of causality. We also suggested that connectives have one constant function: they categorize the causal relation they are used in as an instance of a specific conceptual type. Our suggestion to treat daardoor as representing a distinct conceptual and semantic category will be relatively uncontroversial. Previous studies have argued for a "status aparte" for this connective as well, on the grounds of conceptual and usage argnroents. Pander Maat and Sanders (2000) propose that daardoor conceptually stands apart from daarom and dus because of the fact that the condition for its use is strict: it can only mark SOC-less causal relations. Judging from usage data, in terms of frequency of occurrence of NPU, daardoor certaioly represents the most restrictive category of the three connectives under investigation. However, despite its low frequency, NPU of daardoor into the domain of volitional causality do occur in a rather natural way construing the relation as "SOC-less" (see the discussion ofNPU patterns of daardoor in section 4.3.2). This NPU pattern of occurrence does not differ from those occurring with daarom and dus. Onr suggestion that daarom and dus must be analyzed as similarly distinct categories is perhaps more controversial. A pivotal argument in favor of the "scalarity" interpretation was that the conceptual categories of volitional and epistemic causality show conceptual aflinity: in both types, the source of the causal relation is an volitionally acting animate being, the "Subject of Consciousness" (cf. Section 2). The fact that dus and daarom can be used in both categories was explained with reference to this conceptual connection (Pander 28 This distinction between explicit (propositional) SOC and implicit (nonpropositional) SOC characterizes the difference between daarom and dus (PU and NPU) in our sample better than "absence or presence of reference to the speaker" !56 Ninke Stukker, Ted Sanders and Arie Verhagen Categories of subjectivity in Dutch causal connectives: a usage-based analysis dus is used in an episternic relation - its PU - the relation is "performative" by definition. Analogously, this performative aspect is systematically present in dus' NPU volitional causal contexts of use. A systematic pattern in these contexts of use is the suggestion that the action described is justified, and not only descriptively motivated, which is the standard interpretation when a volitional relation is marked with daarom. Daarom's core meaning, on the other hand, seems to be "objective description". Tills characteristic is not only systematically present in daarom's PU volitional causality, but it is also preserved in its epistemic contexts of use, backgrounding the epistemic context's inherent high level of speaker involvement. These constancies in the effects ofdus and daarom over various contexts have been observed in other studies as well. They were accounted for by the assumption that a scalar concept of subjectivity allows for a certain amount of variation in degrees of subjectivity "tolerated" by the respective causal connectives (cf. Pit's [2003] "tolerance zones"). In the categorization approach proposed here, the constant effect of connectives on the construal of the causal relation can be explained with reference to the cognitive concept of prototypicality structure, and by the cognitive firnction of categorization itself. The cognitive semantic concept of "subjective construal" we introduced in Section 3.1 now adds to the mere observation of constancies, a firnctional explanation of the occurrence itself ofNPU. Our analysis suggests that the ambiguity observed in connectives' NPU contexts serves rhetorical purposes. In the overall interpretation of causal relations in concrete contexts of use, the inherent character of a connective may be "blended" with other contextual factors. Volitional causal relations, fo~ example, are inherently objective. At the same time, the fact that a SOC necessarily does. This finding contradicts the results reported in Pander Maat & Sanders (2000), who found that usage of dus was concentrated in categories that are close to the speaker according to the subjectivity cline of SOC: "unspecified < nominal < pronominal 3'd person < explicit speaker" (2000: 68-70), while daarom was more often used with categories at greater distance from the speaker. Stukker (2005: chapter 4) discusses implications of either pattern for a definition of "subjectivity" in causal coherence relations. Table Nl Distribution of dus and daarom over SOC formulation types within the category "explicit SOC" relations.

Sanders et al. this volume). Conversely, inherent epistemic causal relations may become "objectified" to the extent that their conclusions have their source in outside reality rather than in the speaker's personal consciousness. 29 NPU concerning "category crossing" usages within the domains of objective volitional and non-volitional causality can be analyzed in similar terms: volitional daardoor backgrounds the SOC's volitionality in bringing about the inherently intentional causal relation; non-volitional daarom foregrounds aspects of SOChood in the inherently non-intentional causal relation. An inherent advantage of a categorization approach to connectives is that it allows for integration with related fields of study. There is ample evidence that the categorization firnction per se is crucial in causality markers manifested at the clause-level of linguistic structure as well (e.g. Tahny 1988; Kemmer and Verhagen 1994; Verhagen and Kemmer 1997; Wolff and Song 2003; Stukker, Sanders and Verhagen 2008). Furthermore, the categorization perspective fits in with more general theories of discourse structure- not only because categorical concepts are more easily integrated with the idea that connectives are markers of coherence relations, but also because the categories of objective and subjective causality have a direct parallel in taxonomies of coherence relations (Sanders 2005); moreover, it also aligns with the categorical difference between the connectives in terms oftheir interaction with grammatical negation (Verhagen 2005: 197-205). Despite the fact that we consider these results important, they should be corroborated by an independent investigation from an onomasiological perspective (cf. Geeraerts 1997 for an elaborate discussion of the relation between the semasiological and the onomasiological perspectives). When we introduced Hypothesis 1, we noticed that it inherently addressed the relation between form and meaning in a semasiological way. Given the forms, what do they express: categories or extended areas on a scale? As figure 5 depicts, our present conclusion includes the idea of a tight connection between linguistic and conceptual structure. Tills hypothesis not only predicts the kind of relations between PU and NPU as discussed so far; it specifically also predicts that a particular type of concept, say volitional causality, will typically, and most frequently, be expressed by the associated form. This is the onomasiological question. To see that this is, indeed, an independent issue, consider the distribution of uses we started out with (figure 2), given in table 6. 29 For an analysis ofNPU of daarom and dus in terms of blending of mental spaces, see the contribution of Sanders et al., this volume !58 Ninlre Stukker, Ted Sanders and Arie rerhagen Categories ofsubjectivity in Dutch causal connectives: a usage-based analysis Table 6. Distribution of daardoor. daarom and dus over domains of use in the sample, 30 159 These ratios can now be used to construct table 7 from table 6: ·~ Daardoor Daarom Dus Total 96 16 0 Content Volitional 4 50 Epistemic 0 31 97 22 76 112 76 107 295 Content Non-volitional Total 100 98 Looking at the colunms, it becomes evident that the prototypical use of daardoor is content non-volitional, that of daarom is content volitional, and that of dus is epistemic. Looking at the rows, it seems that the prototypical way of expressing a content non-volitional relation is daardoor, for a content volitiollal relation it is daarom, and for an epistemic relation it is dus. However, the validity of such a conclusion depends on the ratios of use of the three connectives, which is ignored in the table because we sampled I 00 iustances of each connective (in order to have sufficient cases for analysis). For example, if dus would be used five times more often than daarom, the number of cnntent volitional relations marked by dus would be 110 rather than 22, and since this is considerably more than the 50 cases marked with daarom, the protoypical marker for such relations would be dus rather than daarom. Such a situation could then be constructed as an argument for the conclusiou that dus is a kind of"unmarked case", ioheren!ly allowing a range of different uses, whereas daarom would be a "marked case" with an ioherently restricted range oftJSCs. In principle, of course, this issue requires an independent investigation, using a different and independent sampling method. Thus, we cannot give a definitive answer to the onomasiological question here, but we are able to provide good indications why we expect our prediction to be corroborated, viz. by reconstructing the data presented in table 6 in terms of the actual ratios of use of the three connectives in the corpus. The corpus (cf. note 16) was searched for the three connectives in a particular way independent of the kind of relation expressed. 31 On this basis, the ratios of use in this corpus were established as follows: daardoor : daarom : dus I : 1.81 : 3 .II 31 As the search engine does not allow searches that will result in over 3000 hits, 4 combinations ofthe connectives with common words ftom different parts ofspeech were used: with weer ('again'), soms ('sometimes'), dag ('day'), and altijd ('always'). The respective numbers and the resulting ratio•s returned for these are presented in tbe following table: Table 7.

Still, it will be clear that an independent investigation of this issue is called for, and we plan to report this in future research. 5.3. More methodological considerations and future research We consider our results as presenting strong indications in favor of the categorization hypothesis, but the results of the present study generate new research questions as well. For example, taxonomies of coherence relations have treated the distinction between volitional and non-volitional relations as being of secondary importance (cf. Sanders 1992; Sanders et aL 1992, 1993). Our findings suggest that the importaoce of ••animacy" deserves reconsideration in a cognitively plausible theory on discourse structure. 1be categories of volitional ---·· Table Nl Reconsruction of ratios of use. soms Dus 2429 3.07 948 2.73 1192 3.14 1712 3.42 Daarom 1374 1.73 558 1.6 712 1.87 101& 2.03 Daardoor 791 1 347 1 380 1 501 1 weer Total 6281 3.11 3662 1.81 2019 1 ···~--··· As the table shows, the variation between the different combinations is limited, and we therefore conclude that the average ratios in the last column provide a reliable indication of the acrual ratios of use of the connectives in the entire corpus, also in view of the large number of observations. 160 Ninke Stukker, Ted Sanders and Arie Verhagen and non-volitional causality, relevant for distinguishing Dutch daardoor and daarom, show an interesting parallel to the categories of animate and inanimate causality as identified with Dutch causal verbs (Verhagen and Kemmer 1997· see for discussion of the exact parallel Stokker, Sanders and Verhagen 2008: Stokker 2005). Another intriguing finding is that grammaticalized markers of "subjective causality" (a force dynamic interaction at the level of representation) are only found at the discourse-level of language use. These issues will be addressed in future research (see also Stokker, Sanders and Verhagen 2008). Obviously, our stody has limitations as well. A first source oflimitations we want to discuss here is the nature of the methodology we used, which especially affected our analysis ofNPU. Our methodology was built on the usage-based assumption that linguistic knowledge has the form of usage schemas, specifying the type of context in which- in our case- causal connectives may adequately be used. Our method of analysis consisted of investigating observable characteristics of the individual, contextual instances of the more abstract usage schemas. The context's causality type was determined on the basis of paraphrases, which focused on SOC-type and event type of the consequent segment (cf. Section 4.1 ). If the causality type of the context was congruent with the connective's hypothesized inherent meaning, the context was classified as a PU, if it was not congruent with the connective's inherent meaning, it was classified asaNPU. NPU were further analyzed on the basis of other segmental characteristics which could be related to the concepts of animacy and subjectivity (cf. Section 4.2). This analysis revealed converging trends of conceptual affinity,. but it did not include all of the connectives' individual usage contexts. This is partly due to the fact that the present analysis had an explorative character, mainly focusing on patterns and phenomena already reported in previous studies on connectives, or in related fields of stody. But more importantly, since our analysis was restricted to detecting explicit, objectively observable, contextoal indications of subjectivity and animacy, NPU contexts of use not containing explicit indications could not be taken into account. On the basis of the inherent underspecification oflanguage use, we must expect that natural contexts of use exist in which the connective chosen is the only visible indication of the intended causality category (cf. the discussion of NPU of causal verbs in Section 4.1; cf. on connectives Pander Maat and Sanders 2000:76--7). These cases were not included in our analysis. A further limitation, related to the one previously mentioned, is that our methodology did not allow for testing the categorization hypothesis' restrictive- Categories of subjectivity in Dutch causal connectives: a usage-based analysis 161 ness32 . Prototypicality structure inherently defines constraints on the extendibility ofNPU; it predicts that if usage contexts of connectives do not contain any conceptual affinity to the connective's prototype, this usage context is unacceptable33. We can illustrate this prediction with reference to the following examples: (25) Het was extreem koud. # Daardaor zochten we een cafe op. 'It was extremely cold. Daardoor we entered a cafe.' (26) De straten zijn nat. # Daarom zal het wei geregend hebben. 'The streets are wet. Daarom it must have rained.' The connective daardoor leads to an incoherent interpretation (signaled by the symbol#) in the volitional causal context of (25). On the basis of the patterns of use reported for daardoor in Section 4.3, and on the basis of general assumptions in usage-based theory, we can explain the incoherence of this fragment as follows: the context of use of(25), in particular the combination of verb and subject in the consequence clause, is inherently volitional. Daardoor always preserves characteristics of its prototype "non-volitional causality", therefore it can only be used in volitional contexts containing elements of restricted intentionality (which is not the case in this fragment). A similar line of reasoning holds for (26). In this example, a conclusion regarding the plausibility of the proposition in S2 is justified with the argument in S I, while there is no causal relation between the propositions themselves (it is a case of so-called abductive reasoning). In this type of epistemic relations, a high level of speaker involvement is an inherent aspect of the interpretation. Daarom always preserves characteristics of its prototype "volitional causality", not standardly containing speaker involvement; therefore it can only be used in epistemic contexts with moderate speaker involvement (which (26)) is not). In future research, we will try to reduce the impact of the inherent limitations of our usage-based method of analysis by constructing a more elaborate model 32 In part, the inability to define clear boundaries to extendibility of use may be a matter of principle. The usage mechanisms described here imply that it is simply impossible to predict all possible usage types on the basis of theory alone - the inherent underspecification of language use, and the subjective basis of linguistic construal entail that utterance meaning cannot be derived compositionally from its constituting parts, nor be predicted completely in advance (cf. Verhagen 1997). 33 The suggestion that restrictions on connectives' usability may exist was noticed by previous studies as well (cf. Pit's [2003] "tolerance zone" of connectives), but left unexplained. Within the usage-based framework, this fact, too, can be explained with reference to the connectives' prototypical contexts of use. !62 Ninke Stukker, Ted Snnders and Arie Perhagen of analysis, which allows us to measure linguistic and non-linguistic indications of animacy and ~ectivity in a more systematic way. Such a model will enable us to refme and extend our analyses of NPU pattorns (Stukker and Sanders submitted). A second limitation concerns the generalizability of our results. We investigated only one variety of discourse: written newspaper texts. Recent studies have suggested that conventions of connective use are co-determined by context factors, of which modality of communication ( VITitten, spoken, electronic) is an important one (cf. Spooren, Sanders, Huiskes and Degand to appear). A concrete example of the way medislity influences the linguistic expression of causal relations is the distribution of cansality types. In our corpus we hardly encountered "speech act causality", assumed to be a causality category as important as content and epistemic causality are (Sweetser 1990; Spooren et al. to appear; see for discussion Sanders et al. this volume; Sanders and Spooren this volume). Evidently, ifwe are to give a complete account of the relation between the linguistic expression of cansality and cognitive concepts, we should extend our field of study to other discourse types as well (cf. Sanders 2005). Furthermore, the analysis presented here does not decide how the usage patterns found are reflected in the language user's mental representation of the semantic categories of the connectives under investigation. Our findings suggest that the connectives' PU \lave a special status in tbe language users' lingnistic knowledge. But we don't know whether besides these prototypical cores other usage types have attained the status of conventionalized, entrenched usage schema (cf. Langacker 1987, 2000), e.g. as conventionalized "blending" schemas (cf. Sanders et al. this volume). For example, how must we interpret frequency differences among NPU of daarom and duson the one hand, and daardoor on the other? The specific distribution patterns we found suggest that the relatively frequent occurrence ofNPU of daarom and du.s may have formed an independently entrenched, conventionalized subschema in the language user's mental representation of semantic knowledge (cf. Langacker 2000; Bybee 2006, 2007) which is less likely with respect to the relatively unfrequent NPU of daardoor. But even if this is the case, our analysis suggests that the categories of subjectivity as proposed here (i.e. volitional causality and epistemic causality) provide for the essential level of generalization. Future analyses of other text genres and medialities will address the question to what extent the frequeuey. differences arnoog NPU patterns form a stable pattem across varieties of discourse (e.g. because of a relatively high fimctional value of ambiguity between objective and subjective causality in human communication; or because of in~ herent conceptual affinity- cf. Pander Maat and Sanders 2000) or whether they are restricted to the newspaper discourse investigated. Categories ofsubjectivity in Dutch causal connectives: a usage-based analysis 163 A final - but crucial issue for further research we want to address here is: what is the role of the connective in the overall interpretation of the causal relation, as opposed to other lingnistic indications of subjectivity in the context? Our construal analysis suggests that a connective has the effect of foregrounding aspects of subjectivity io the connective's context of use that are congruent with the connective's meaning. Tills effect comes out cle.arest in our analysis ofNPU, defined in our analysis as contexts ofuse which are ambiguous for causality type. The construal analysis predicts that the coiDleLiive used to mark the arnbigunus relation foregrounds the aspects that are congruent with the connectives function of ascribing the causal relation at hand to the conceptual type of causality the connective is associated with. Elements in the contexts that are incongruent with this connective's function may be backgrounded, but they \viii still play a rol in the relation's overall interpretation. The resulting interpretation may be characterized as a "blend" of causality types, in the sense proposed by Sanders et al. (this volume).1bis question will be investigated further in future research that aims at analyzing the contexts of connective use in greater detail (Stokker and Sanders submitted). 5.4. Conclusion Testing hypotheses eoncemiog language structure against data from namrallanguage use is a method commonly accepted in functional and cognitive linguistics. However, the extent to which different approaches acknowledge the role of language use mechanisms in resulting theories and descriptions varies strongly. If corpus analysis is used as a method for testing hypotheses concerning the relation between language and cognition; an obvious prereqnisite is that cognitive mechanisms manifest at the level oflanguage use are taken into account as well. The analysis presented in the present paper shows how a usage based approach to language use data adds to our understanding of the relation between language structure, cognitive structure, and language use. We believe that the usage-based analysis of connectives proposed here has advantages from an empirical as well as from a theoretical perspective. It allows for generalization over usage contexts per connective, just like the subjectivity scale proposed by previous approaches did, but it also explains concrete, observable usage putterns, such as clustering of usage types and flexibility of use, as a consequence of more general mechanisms governing language nse and of general cognitive mechanisms such as the categorization function and prototypicality structure. Thus, the usage-based perspective proposed in this paper adds to the descriptive power as well as to the cognitive plausibility of the analysis of causal cmmectives. 164 Ninke Stukker, Ted Sanders and Arie Yerhagen Categories ofsubjectivity in Dutch causal connectives: a usage-based analysis Acknowledgements Appendix2 We would like to thank Barbara Dancygier and Dirk Geeraerts for their insightful comments on an earlier version of tltis paper, which made us reconsider some aspects of our proposal, and Huub van den Bergh for invaluable advice on statistic analysis.
