ABSTRACT
Since there are so many languages to be dealt with it would be impracticable to give even an outline of the main features of each of them. To keep the work within limits an outline is given of the main characteristics of each group separately. To do this 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.
