Originally published as the Continuum Companion to Phonology, this book offers the definitive guide to a key area of linguistic study. It covers all the most important issues, concepts, movements and approaches in the field. Each companion offers a comprehensive reference resource giving an overview of key topics, research areas, new directions and a manageable guide to beginning or developing research in the field. It offers a survey of current research and also gives more practical guidance on advanced study and research in the area. The book includes coverage of key research areas in phonology, including the interaction of phonology with other areas of linguistics while also providing some guidance on how phonological research can be conducted in the field and in the laboratory. It moves from coverage of the smallest units such as features and syllables to larger units incorporating phrasal and prosodic structure. It is a complete resource for postgraduate students and researchers working in phonology.
