This paper offers a new unified theory about the meaning of the imperfective and progressive aspects that builds on earlier of analyses in the literature that treat the imperfective as denoting a universal quantifier (e.g. Bonomi, Linguist Philos, 20(5):469–514, 1997; Cipria and Roberts, Nat Lang Semant 8(4):297–347, 2000). It is shown that the problems associated with such an analysis can be overcome if the domain of the universal quantifier is taken to be a partition of a future extending interval into (...) equimeasured cells. Treating the partition-measure (the length of each partition-cell) as a contextually dependent variable allows for a unified treatment of the habitual and event-in-progress readings of the imperfective. It is argued that the contrast between the imperfective and the progressive has to do with whether the quantifier domain is a regular partition of the reference interval or a superinterval of the reference interval.

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)

I might summarize this section by saying that the English tenses, according to this analysis, form quite a motley group. PAST, PRES and FUT serve to relate reference time to speech time, while WOULD and USED-TO behave like Priorian operators, shifting the point of evaluation away from the reference time. HAVE also shifts the point of evaluation away from the reference time, but in a more complicated way. And FUT, in contrast to PRES and PAST, is a substitution operator, putting (...) the reference time of its clause in the plate of the speech time of subordinate clauses. (shrink)

Maximize Presupposition! is an economy condition that adjudicates between contextually equivalent competing structures. Building on data discovered by O. Percus, I will argue that the constraint is checked in the local contexts of embedded constituents. I will argue that this architecture leads to a general solution to the problem of antipresupposition projection, and also allows I. Heim’s ‘Novelty/Familiarity Condition’ to be eliminated as a constraint on operations of context change.

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.
