Language of Turn and Sequence [PDF ebook] 

This collection of previously unpublished, cutting-edge research discusses the conversation analysis (CA) approach to understanding language use. CA is the dominant theory for analyzing the social use of language and is concerned with the description of how speakers engage in conversation and other forms of social interaction involving language. Its proponents are not only linguists but sociologists and anthropologists as well. The unifying theme of these chapters is the intersection of practice and form through the construction of turns and sequences.
