Linguistic Analyses: The Non-Bantu Languages of North-Eastern Africa [EPUB ebook] 
Handbook of African Languages

This book, originally published in 1966, deals mainly with morphemes and with grammatical and syntactic behaviour. Although some vocabulary material is contained in this volume, and some more in the Linguistic Survey of the Northern Bantu Borderland, vocabulary comparison itself plays little part. The volume presents an overall picture of the working of representative languages from each section of the Handbook and provides grammatical material which will help future students in classifying the languages to their typological as apart from their lexical features.
