Paraguayan Guarani does not overtly mark tense in its inflectional system. Prior accounts of languages without obligatory morphological tense have posited a phonologically covert lexical tense, or have introduced tense semantics via a rule, in the post-syntactic interpretative component. We offer a more radical approach: Paraguayan Guarani does not have tense at the level of lexical or logical semantics. We propose that evaluation time shift, a mechanism independently attested in the narrative present in languages with tense, is more widely used (...) in Paraguayan Guarani for encoding temporal meaning. The broader consequence of our proposal is that tense is not a linguistic universal. (shrink)

This paper provides a formal semantic analysis of past interpretation in Medumba, a graded tense language. Based on original fieldwork, the study explores the empirical behavior and meaning contribution of graded past morphemes in Medumba and relates these to the account of the phenomenon proposed in Cable for Gĩkũyũ. Investigation reveals that the behavior of Medumba gradedness markers differs from that of their Gĩkũyũ counterparts in meaningful ways and, more broadly, discourages an analysis as presuppositional eventuality or reference time modifiers. (...) Instead, the Medumba markers are most appropriately analyzed as quantificational tenses. It also turns out that Medumba, though belonging to the typological class of graded tense languages, shows intriguing similarities to genuinely tenseless languages in allowing for temporally unmarked sentences and exploiting aspectual and pragmatic cues for reference time resolution. The more general cross-linguistic implication of the study is that the set of languages often subsumed under the label “graded tense” does not in fact form a natural class and that more case-by-case research is needed to refine this category.

In this paper, I analyze the verbal suffix -uŋil in Washo as an optional past tense. It is optional in the sense that it is not part of a paradigm of tenses, and morphologically tenseless clauses are also compatible with past time reference. Specifically, I claim that -uŋil is the morphological exponent of a tense feature [past], which presupposes that the reference time of the clause, denoted by a temporal pronoun, precedes the evaluation time. Meanwhile, morphologically tenseless clauses lack a (...) semantic tense restricting the value of the reference time pronoun. In comparing this analysis with one containing a covert non-future tense in morphologically tenseless clauses, I show that the range of empirical contexts that distinguish these analyses is quite narrow. However, I offer a novel argument against a covert tense analysis based on the lack of Maximize Presupposition effects. Crucially, the fact that -uŋil does not form a paradigm of tenses results in a failure for Maximize Presupposition to apply. The proposed analysis places cross-linguistic variation at the level of the paradigm of tense features, namely whether they are present or absent, and if present, whether obligatorily so. This case study from Washo thus reveals what a language where tense features are optional can look like, and more generally contributes to the growing body of literature on cross-linguistic semantics devoted to uncovering the ways in which temporal interpretation can be achieved in natural language.
