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. Varieties. Blench (2019) lists these language varieties as part of the Koma cluster. The Ndera, Gimnime, and Kompana language varieties are spoken in the central part of the Alantika Mountains and part of the Faro plains located at the foot of the Alantika Mountains (in  the central part of Béka commune, Faro department, Northern Region). The varieties listed in "ALCAM" (2012) are as follows, listed from north to south: Although they are also referred to by the local government as "Koma Ndera", "Koma Kadam", and "Koma Kompana", the term "Koma" itself is not used by any of these groups. The name "Koma Ndera" is used by the Fulbe and the local Cameroonian government. "Ndera" is derived from the name of a village. Also, the terms "Doabe" (ethnonym; name referring to the ethnic group) and "Doome" (glossonym; name referring to the language) are used by the  neighboring Gimbe, including the Kobo, who speak a language closely related to Koma Ndera. "Léélu", "Bangru", "Zanu", "Liu", and "Yéru" are the ethnonyms (plural forms) corresponding respectively to the villages Ndera, Mougini, Boge, Li, and Gede. Koma Ndera is found in Faro department, Northern Region (northwest of the Chamba Leko area) and is also spoken in Nigeria.
