Koma language

The Koma language is a language cluster belonging to the Duru branch of Savannas languages of Cameroon. Blench (2004) includes three varieties separated in "Ethnologue", Koma Ndera, Gɨmne, and Gɨmnɨme; within Koma Ndera, speakers of the marginal dialects, Gomnome and Ndera, can scarcely understand one another, though both understand the central dialect, Gomme.
