Diphthongisation and coindexing

Abstract

The tree model of segment structure proposed by Clements (1985) is an important innovation in phonological theory, making possible a number of interesting predictions about the form of phonological rules, locality of rule application, and the organisation of the feature system. Clements' proposal has given rise to an expanding literature, including Sagey (1986), Schein & Steriade (1986), McCarthy (1988), Archangeli & Pulleyblank (forthcoming) and other work.
