The area covered by this book, originally published in 1953, is one that has long been recognized as presenting many problems from the point of view of Bantu linguistic studies. Almost all the material set out in this present work is based on notes taken in the field, and in many cases presented completely new facts. The sources of the information used are listed at the end of the linguistic description of each of the groups of languages dealt with. Since there are so many languages to be covered it would be impracticable to give even an outline of the main features of each of them, so an outline is given of the main characteristics of each separate group. One language is used as the type for each group, for the purpose of listing examples of the nominal prefixes, verbal conjugation, and personal prefixes. Other features are illustrated from whichever language is the most suitable.
