An introduction to the general linguistic study of aspect. Topics covered include the relation of tense and aspect, the morphology and the semantics of aspect, and structuralist and philosophical approaches. Dr Comrie draws his examples particularly from English and the Slavonic and Romance languages, but also from Arabic, Chinese, Welsh, Greek and a variety of others. This is the first study of aspect, considered as a general linguistic phenomenon. It is intended for students of individual languages as well as for students of linguistics.
