Book excerpt: This book is an introduction to African languages and linguistics, covering typology, structure and sociolinguistics. The twelve chapters are written by a team of fifteen eminent Africanists, and their topics include the four major language groupings (Niger-Congo, Nilo-Saharan, Afroasiatic and Khoisan), the core areas of modern theoretical linguistics (phonology, morphology, syntax), typology, sociolinguistics, comparative linguistics, and language, history and society. Basic concepts and terminology are explained for undergraduates and non-specialist readers, but each chapter also provides an overview of the state of the art in its field, and as such will be referred to also by more advanced students and general linguists. The book brings this range of material together in accessible form for anyone wishing to learn more about this challenging and fascinating field.
