A detailed study of Old English, taking as its point of departure the 'standard theory' of generative phonology as developed by Chomsky and Halle. Dr Lass and Dr Anderson set out all the main phonological processes of Old English and against their larger historical background (including subsequent developments in the history of English). They propose many fresh solutions to long-standing problems in the history and structure of Old English. The result is an extensive and sophisticated treatment of this subject. An important theory is examined against a well-studied body of linguistic knowledge, and is partly validated and partly revised. The book will be important for all linguistics and historians of English and Indo-European.
