Abstract:
This dissertation investigates the semantics of tense and aspect in natural language sentences. Its goal is to develop a compositional, model-theoretic semantics for tense and temporal adverbs which is sensitive to aspectual distinction, with a clear syntax-semantics interface, with wide empirical coverage, for a number of different languages. My analysis will be mainly concerned with tense and aspect in Romance languages. In the discussion, I will argue that if we look at the durative adverbial distribution and the aspectual contrasts across the different morphological tense forms, we discover that the homogeneity character of the tense complement plays a fundamental role in tense selection in Romance languages. In order to explain these facts, I will assume that tenses are sensitive to the temporal homogeneity of their complement in Romance languages. I will bring some additional evidence to the hypothesis that the temporal homogeneity of the tense complement plays a fundamental role in tense selection in other domains such as habitual and generic meanings and state of result constructions. In chapter 1 I will discuss some of the accounts of tense and aspect and I will present a temporal architecture of tensed sentences which is sensitive to aspectual distinction and verb classes differences. In chapter 2, I will illustrate and formalize the “homogeneity” proposal. In chapter 3, I will explore the extension of the proposal to English. Finally, in chapter 4, I will integrate the linguistic introspective facts discussed in this dissertation with data from an empirical study.
