Book excerpt: Generative Phonology: Description and Theory provides a basic understanding of the fundamental concepts of generative phonology and the applications of these concepts in further study of phonological structure. This book is composed of 10 chapters and begins with a survey of phonology in the overall model of generative grammar and introduces the principles of phonetics to. The subsequent chapters introduce the fundamental concept of a phonological rule that relates an underlying representation to a phonetic representation and this concept is applied to the analysis of morphophonemic alternation. These topics are followed by a presentation of phonological sketches of four diverse languages in terms of rules relating underlying and phonetic representations, as well as the major corpus-internal principles and techniques of phonological analysis. The discussion then shifts to the theoretical aspects of phonology, the various degrees of abstractness, and the proposals to limit the divergence between underlying and phonetic representation. Other chapters deal with some of the issues revolving around the representation of sounds and the various hypotheses as to how phonological rules apply to convert the underlying representation to the phonetic representation, particularly the kinds of considerations that motivate rule-ordering statements. The last chapters explore the major notational devices commonly employed in the formulation of phonological rules and the role of syntactic and lexical information in controlling the application of phonological rules. This book is intended primarily for linguistics and phonologists.
