The tenth volume in Professor M.A.K. Halliday's collected works consist of papers focusing on Language and Society. The chapters provide a framework for understanding the social meaning of language, and the relation of language to other social phenomena. The volume begins with Professor Halliday's ground-breaking work on the users and uses of language. Subsequent chapters are organized around a discussion of sociolinguistic theory, and the relation between language, social class and social structure.
