Morphology is a lively, comprehensive introduction to current morphological theory and analysis, designed to take absolute beginners to a point where they can approach the current literature in the subject. This revised and updated second edition contains numerous in-text exercises which involve the reader in doing morphology by formulating hypotheses and testing them against data from English and numerous other languages. It also features an additional chapter on optimality theory and an expanded list of reading suggestions to take the student further into a particular area. The book is divided into three parts: - Part I surveys traditional and structuralist notions of word-structure which still provide the necessary background to morphological investigations - Part II explores the relationship between the lexicon, morphology and phonology in current generative grammar - Part III examines issues in the interaction between the lexicon, morphology and syntax. Stimulating and easy-to-follow, this is an essential guide to a fundamental subject within the field of linguistics.
