The second edition of this successful introductory guide has been thoroughly revised, updated, and expanded to take into account the latest developments and current teaching. It now features three new chapters covering Moraic Theory and Optimality Theory, as well as new exercises and suggestions for further readings.
Honestly... I wouldn't recommend this as an introduction to phonology. It's got difficult writing, doesn't explain key concepts clearly, and most of the exercises do not have answers, so you can't really check whether you understand the key concepts or not. In short, it doesn't do the subject of phonology justice.
