This paper contributes data from Paraguayan Guaraní (Tupí-Guaraní) to the discussion of how temporal reference is determined in tenseless languages. The empirical focus of this study is on finite clauses headed by verbs inflected only for person/number information, which are compatible only with non-future temporal reference in most matrix clause contexts. The paper first explores the possibility of accounting for the temporal reference of such clauses with a phonologically empty non-future tense morpheme, along the lines of Matthewson’s (Linguist Philos 29:673–713, (...) 2006 ) analysis of a similar phenomenon in St’át’imcets (Salish). This analysis is then contrasted with one according to which temporal reference is not constrained by tense in Paraguayan Guaraní, but only by context and temporal adverbials. A comparison of the two analyses, both of which are couched in a dynamic semantic framework, suggests empirical and theoretical advantages of the tenseless analysis over the tensed one. The paper concludes with a discussion of cross-linguistic variation of temporal reference in tensed and tenseless languages. (shrink)

In the tradition of quantified modal logic, it was assumed that significantly different linguistic systems underlie reference to individuals, to times and to ‘possible worlds’. Various results from recent research in formal semantics suggest that this is not so, and that there is in fact apervasive symmetrybetween the linguistic means with which we refer to these three domains. Reference to individuals, times and worlds is uniformly effected through generalized quantifiers, definite descriptions, and pronouns, and in each domain grammatical features situate (...) the reference of terms as near, far or ‘further’ from the actual or from a reported speech act. We outline various directions in which a program ofontological symmetrycould be developed, and we offer in theAppendixa symmetric fragment developed in a logic that can be seen as a compromise between an extensional and an intensional system.

Modals in St’át’imcets (Lillooet Salish) show two differences from their counterparts in English. First, they have variable quantificational force, systematically allowing both possibility and necessity interpretations; and second, they lexically restrict the conversational background, distinguishing for example between deontic and (several kinds of) epistemic modality. We provide an analysis of the St’át’imcets modals according to which they are akin to specific indefinites in the nominal domain. They introduce choice function variables which select a subset of the accessible worlds. Following Klinedinst, (...) we assume distributivity over the resulting set of worlds. St’át’imcets modals thus receive a uniform interpretation as (distributive) pluralities. The appearance of variability in modal force arises because the choice function can select a larger or smaller subset of accessible worlds. Finally, we discuss the implications of our analysis for the investigation of modal systems in other languages. (shrink)

In this paper I assume that syntactic structures contain items that function as variables over possible worlds (or things like possible worlds). I show that in certain syntactic positions we can use some variables but not other. I accordingly motivate a "binding theory" for the items that occupy these positions, and I discuss some consequences of this binding theory.

This paper contributes to the debate about ‘tenseless languages’ by defending a tensed analysis of a superficially tenseless language. The language investigated is St’át’imcets (Lillooet Salish). I argue that although St’át’imcets lacks overt tense morphology, every finite clause in the language possesses a phonologically covert tense morpheme; this tense morpheme restricts the reference time to being non-future. Future interpretations, as well as ‘past future’ would-readings, are obtained by the combination of covert tense with an operator analogous to Abusch’s (1985) WOLL. (...) I offer St’át’imcets-internal evidence (of a kind not previously adduced) that the WOLL-like operator is modal in nature. It follows from the analysis presented here that there are only two (probably related) differences between St’át’imcets and English in the area of tense. The first is that St’át’imcets lacks tense morphemes which are pronounced. The second is that the St’át’imcets tense morpheme is semantically underspecified compared to English ones. In each of these respects, the St’át’imcets tense morpheme displays similar properties to pronouns, which may be covert and which may fail to distinguish person, number or gender. Along the way, I point out several striking and subtle similarities in the interpretive possibilities of St’át’imcets and English. I suggest that these similarities may reveal non-accidental properties of tense systems in natural language. I conclude with discussion of the implications of the analysis for cross-linguistic variation, learnability and the possible existence of tenseless languages. (shrink)

In recent years, our understanding of how tense systems vary across languages has been greatly advanced by formal semantic study of languages exhibiting fewer tense categories than the three commonly found in European languages. However, it has also often been reported that languages can sometimes distinguish more than three tenses. Such languages appear to have ‘graded tense’ systems, where the tense morphology serves to track how far into the past or future a reported event occurs. This paper presents a formal (...) semantic analysis of the tense-aspect system of Gĩkũyũ , a Northeastern Bantu language of Kenya. Like many languages of the Bantu family, Gĩkũyũ appears to exhibit a graded tense system, wherein four grades of past tense and three grades of future tense are distinguished. I argue that the prefixes traditionally labeled as ‘tenses’ in Gĩkũyũ exhibit important differences from tenses in languages like English. Although, like tenses in English, these ‘temporal remoteness prefixes’ in Gĩkũyũ introduce presuppositions regarding a temporal parameter of the clause, in Gĩkũyũ these presuppositions concern the ‘event time’ of the clause directly, rather than the ‘topic time’. Consequently, the key difference between Gĩkũyũ and languages like English lies not in how many tenses are distinguished, but in whether tense-like features are able to modify other, lower verbal functional projections in the clause.

The Eskimo language Kalaallisut (alias West Greenlandic) has traditionally been described as having a rich tense system, with three future tenses (Kleinschmidt 1851, Bergsland 1955, Fortescue 1984) and possibly four past tenses (Fortescue 1984). Recently however, Shaer (2003) has challenged these traditional claims, arguing that Kalaallisut is in fact tenseless.

It has long been recognized that temporal anaphora in French and English depends on the aspectual distinction between events and states. For example, temporal location as well as temporal update depends on the aspectual type. This paper presents a general theory of aspect-based temporal anaphora, which extends from languages with grammatical tenses (like French and English) to tenseless languages (e.g. Kalaallisut). This theory also extends to additional aspect-dependent phenomena and to non-atomic aspectual types, processes and habits, which license anaphora to (...) proper atomic parts (cf. nominal pluralities and kinds).

In English, discourse reference to time involves grammatical tenses interpreted as temporal anaphors. Recently, it has been argued that conditionals involve modal discourse anaphora expressed by a parallel grammatical system of anaphoric modals. Based on evidence from Kalaallisut, this paper argues that temporal and modal anaphora can be just as precise in a language that does not have either grammatical category. Instead, temporal anaphora directly targets eventualities of verbs, without mediating tenses, while modal anaphora involves anaphoric moods and/or attitudinal verbs.

This article presents an account of temporal understanding in Mandarin Chinese. Aspectual, lexical, and adverbial information, and pragmatic principles all contribute to the interpretation of temporal location. Aspectual viewpoint and situation type give information in the absence of explicit temporal forms. The main, default pattern of interpretation is deictic. The pragmatic principles are the Bounded Event Constraint, the Simplicity Principle of Interpretation, and the Temporal Schema Principle. Lexical and adverbial information can lead to non-default interpretations. Two other temporal patterns, narrative (...) dynamism and anaphora, appear in text passages that realize the 'discourse modes' of narrative and description. (shrink)

This article proposes an explanation of the way information about time is conveyed in Navajo.1 We assume that all sentences have a temporal interpretation, direct or indirect. We have two main purposes in this article. The first is to discuss temporal interpretation in this Athabaskan language. The Navajo temporal system, which is varied, has not yet been described in detail. Further, the language allows sentences without explicit temporal information. In such sentences temporal interpretation is indirect - arrived at by inference. (...) We outline the principles underlying the default inferences. Our second purpose is to show that a few general principles of temporal interpretation, which hold for some other languages, apply very nicely to Navajo. The principles include semantic rules for 1 interpreting explicit expressions about time, and pragmatic principles for inferring temporal location indirectly. The applicability of these principles to Navajo is a satisfying though unsurprising result; but it is worth working out explicitly. The temporal system of Navajo offers a future verb inflection, temporal particles, and temporal adverbs. Although a well-formed sentence need not have any of these forms, speakers consistently agree on temporal interpretation. To account for these facts, we must consider sentences with and without direct temporal information. In this article we propose semantic and pragmatic principles that account for both types of cases. The temporal interpretation of all sentences is deictically based. For sentences without direct temporal forms, aspectual information allows the inference of temporal location. We propose three general pragmatic principles to account for this, which we call temporal interpretation: the Deictic Principle, the Bounded Event Constraint, and a Simplicity Principle. The key factor in temporal inference is boundedness, direct or inferred. To arrive at the inference of boundedness we use the Temporal Schema Principle, a special case of the simplicity principle..
