This book describes and analyzes the lexical phonology and morphology of the verb stem in Ciyao, a Bantu language spoken in Southern Malawi, Northwestern Mozambique, and Southern Tanzania. This is the most complete and authoritative treatment to date of the complex morphophonemics of the Ciyao verb, including the stem and derivational and inflexional endings. Dr Ngunga's monograph also contributes significantly to the linguistic documentation of Ciyao by providing an extraordinary collection of examples and two appendices listing nearly 3000 Ciyao verbs.

Only recently discovered by linguistic scholars, Tondi Songway Kiini (TSK) is a tonal language spoken in the small country of Mali in western Africa. Unlike other Songhay languages, TSK preserves the lexical and grammatical tones of its proto-language and also exhibits unique systems for the expression of focalization and relativization." Tondi Songway Kiini "is a valuable overview of the grammar of an African language with a tone system quite different from that of the more familiar Bantu system. It is also an irreplaceable guide to the grammar and meanings of this unusual African language.
