This Cahiers Chronos volume reports on new and ongoing research on tense, aspect and modality in which a variety of languages has been gathered. The languages discussed by the authors include (in alphabetical order): Brazilian Portuguese, Chinese, Dutch, English, French, German, Greek, Italian, Japanese, Polish, Russian and Spanish. The articles form a selection of the papers presented at the 5th Chronos Conference that took place at the University of Groningen, the Netherlands, in June 2002. We have categorized the papers into three sections: Tense, Aspect and Modality. Obviously, this ordering is somewhat arbitrary given that some of the papers cross these rather rigid boundaries, as they discuss the interplay of tense and aspect or tense and modality. This book is of interest for scholars in the field of semantics, logic, syntax, and comparative linguistics.
