Taking a corpus linguistic perspective, Community and Identity in Teacher Professional Talk addresses the central question of how professional communities are constructed through language. This book explores the relatively neglected site of professional discourse, teacher talk outside of the classroom, and examines the possibilities and challenges of operationalising an existing social theory to interpret evidence generated using corpus-based methodologies. Demonstrating how powerful corpus methodologies can be for the study of language in context, this book is essesntial reading for those doing research on professional discourse and corpus linguistics.
