SYNOPSIS Nyanga is a Bantu language of the north‐eastern Congo, in which tone alone may differentiate verbal forms. Some tense morphemes always bear the same toneme, whereas others bear a toneme which varies for different tenses. A list of such morphemes is given with illustrative examples. The tonomorpheme of the radical, on the other hand, is invariable except for radicals of VC type, in which the tone on the initial vowel is identical with the preceding tone, in certain tenses. The segmental and suprasegmental structures of the infinitive are given in detail.
