This 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. The papers have been categorized into three sections: Tense, Aspect and Modality. Some of the papers cross these rather rigid boundaries, as they discuss the interplay of tense and aspect or tense and modality.
