This volume aims at presenting a phonological theory of segmental structure which is capable of providing adequate representations of complex segments, focusing mainly on phonological place and manner. In the first few chapters, a theory of segmental structure is presented which makes it possible to derive a set of complex segments which includes affricates, prenasalised stops, consonants with secondary articulation and short diphthongs. In the final chapters, a thorough investigation is presented of the behaviour of such segments in phonological processes.
