Historical Linguistics provides a comprehensive and clearly written introduction to historical linguistic theory and methods. Since its first publication in 1962 the book has established itself as core reading for students of linguistics. This edition has been thoroughly revised. Drawing on recent linguistic and archaeological research Professor Lehmann incorporates key developments in the field. These include exciting advances in the history and development of writing: and in typological classification which allows better understanding of the structure of early languages. Well-illustrated with Indo-European examples, and supplementary exercises which draw on data from other language families as well, the book will enable students to carry out independent work in historical studies on any language family, as well as up-to-date work in Indo-European.
