This text is an overview of the post-SPE theory of generative phonology, suitable for linguists not specializing in phonology, but who want to keep abreast of the latest developments in the subject. It covers all the major trends in "non-linear" phonology, including particle, dependancy and charm phonology. Iggy Roca guides the reader through the developments of the various approaches, justifying their rationale against the background of SPE machinery, and providing the reader with the basic tools necessary to penetrate current problems and debates. Generative Phonology aims to integrate the modules and proposals of what can seem a fragmentary field into a cohesive body of living theory.
