A phonological study of the four Gwari lects (Nigeria): Northern and Southern Gbagyi, and Northern and Southern Gbari. By making an analysis of each dialect, the author seeks greater understanding of the phonology of Gwari as a whole.

Traditional segmental phonology is the theoretical framework of this study.
