Fully revised and updated for the second edition, this invaluable work is the most authoritative dictionary of linguistics of its kind available.The dictionary covers every aspect of this multidisciplinary field, including sociolinguistics, language theory and history, language families, and major languages from all over the world (including major national/regional dialects), phonetics, formal semantics, and key figures and ideas in linguistics.

With over 150 new entries, the dictionary now boasts greatly enhanced coverage of sociolinguistics, new entries on notable recent theorists in the field, such as Del Hymes and Peter Trudgill, and expanded coverage of regional dialects, such as Estuary English. Wide-ranging and accessible, this dictionary is an ideal reference for undergraduate students and teachers in language-related courses, and a great introduction to linguistics for the general reader with an interest in the theory and structure of language.
