This paper provides a linguistic semantic analysis of time and aspect in natural languages. On the basis of topological concepts, notions are introduced like the basic aspectual opposition between event, state and process or that of time of utterance (for the treatment of deictic categories) that are used to analyse the semantics of grammatical tenses or more general situations. This linguistic...

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 languag...

Explaining how children infer grammatical rules based on their limited finite experience is central to the hypothesis of universal grammar—that collection of inductive principles which allows learning to happen. Because children and languages are complex and many factors influence acquisition—physiological, sociolinguistic, articulatory, perceptual, phonological, syntactic, semantic—a simpler q...

when studying russian morphology, one can distinguish two categories. these categories are “grammatical” and “lexico-grammatical”. grammatical categories can be specified through a series of grammatical features of words. considering different criteria, russian grammarians and linguists divide grammatical categories of their language into different types. in determining lexico-grammatical types...
