Derek Nurse looks at variations in the form and function of tense and aspect in Bantu, a branch of Niger-Congo, the world's largest language phylum. Bantu languages are spoken in central, eastern, and southern sub-Saharan Africa south of a line between Nigeria and Somalia. By current estimates there are between 250 and 600 of them, as yet neither adequately classified nor fully described. Professor Nurse's account is based on data from more than 200 Bantu languages and varieties, a representative sample of which is freely available on the publisher's website. He devotes substantial chapters to the analysis and comparison of the different tense and aspect systems found in Bantu. He also examines the verbal categories with which they interact, including negation and focus. Synchronic and diachronic perspectives are interwoven throughout the book. Following a brief history of Bantu over the last five thousand years, the final two chapters look systematically at the history of tense and aspect in Bantu. The first deals with the reconstruction of the earlier forms from which contemporary structures, morphemes, and categories are derived, and the second with the processes of change, including grammaticalization, by means of which older analytical structures and independent lexical items moved as they became incorporated as grammatical inflections and categories.

Nyakyusa is an underdescribed Bantu language spoken by around 800.000 speakers in the Mbeya Region of Tanzania. This book provides a detailled description of the verb in this language. The topics covered include the complex morphophonological and morphological processes as well as verb-to-verb derivation, copula verbs and grammaticalized verbs of motion. The main body of the book consists of a detailed description of tense, aspect and modality constructions, which includes not only an in-depth discussion of their sentence level semantics, but also of their patterns of employment in discourse.

The twenty-one papers that make up this volume reflect the broad perspective of African linguistic typology studies today. Where previous volumes would present language material from a very restricted area and perspective, the present contributions reflect the global interest and orientation of current African linguistic studies. The studies are nearly all implicational in nature. Based upon a detailed survey of a particular linguistic phenomenon in a given language or language area conclusions are drawn about the general nature about this phenomenon in the languages of Africa and beyond. They represent as such a first step that may ultimately lead to a more thorough understanding of African linguistic structures. This approach is well justified. Taking the other road, attempting to pick out linguistic details from often fairly superficially documented languages runs the risk that the data and its implications for the structure investigated might be misunderstood. Consequentially only very few studies of this nature giving the very broad perspective, the overview of a particular structure type covering the whole African continent are represented here.

Gerard Philippson is Professor of Bantu Languages at the Institut National des Langues et Civilisations Orientales and is a member of the Dyamique de Langage research team of the Centre National de la Recherche Scientifique, Lyon II University. He has mainly worked on comparative Bantu tonology. Other areas of interest include Afro-Asiatic, general phonology, linguistic classification and its correlation with population genetics.
