Tense and aspect are means by which language refers to time--how an event takes place in the past, present, or future. They play a key role in understanding the grammar and structure of all languages, and interest in them reaches across linguistics. The Oxford Handbook of Tense and Aspect is a comprehensive, authoritative, and accessible guide to the topics and theories that currently form the front line of research into tense, aspect, and related areas. The volume contains 36 chapters, divided into 6 sections, written by internationally known experts in theoretical linguistics.
