Book excerpt: Phonology - the study of how the sounds of speech are represented in our minds - is one of the core areas of linguistic theory, and is central to the study of human language. This handbook brings together the world's leading experts in phonology to present the most comprehensive and detailed overview of the field. Focusing on research and the most influential theories, the authors discuss each of the central issues in phonological theory, explore a variety of empirical phenomena, and show how phonology interacts with other aspects of language such as syntax, morphology, phonetics, and language acquisition. Providing a one-stop guide to every aspect of this important field, The Cambridge Handbook of Phonology will serve as an invaluable source of readings for advanced undergraduate and graduate students, an informative overview for linguists and a useful starting point for anyone beginning phonological research.
