This book "asserts that the origin and spread of languages must be examined primarily through the time-tested techniques of linguistic analysis, rather than those of evolutionary biology" and "defends traditional practices in historical linguistics while remaining open to new techniques, including computational methods" and "will appeal to readers interested in world history and world geography."
Ekoid Bantu Languages of Ogoja, Eastern Nigeria: Part 1, Introduction, Phonology and Comparative Vocabulary
Dr Crabb's 1965 study of the Ekoid Bantu languages of Ogoja examines these related languages as a basis of comparative historical research. He has chosen fourteen of these Ekoid languages as representative of a number of languages in the north-west area of Nigeria bordering on the Bantu language area, whose status as Bantu languages has been open to question. This study is based on extensive field work and presents comparatively the phonologies and selected vocabularies of the languages.
