Linguistics has traditionally concentrated on studying single sentences or isolated speech acts. In this book Michael Stubbs explores one of the most promising new directions in contemporary linguistics-the study of many sentences and how they fit together to form discourse. Using many examples drawn from recorded conversations, fieldwork observations, experimental data, and written texts, he discusses such questions as how far discourse structure is comparable to sentence structure; whether it is possible to talk of "well formed" discourse as one does of "grammatical" sentences; and whether the relation between question and answer in conversation is syntactic, semantic, or pragmatic.
