Bata language

Bata (Gbwata) is an Afro-Asiatic language spoken in Nigeria in Adamawa State in the Numan, Song, Fufore and Mubi LGAs, and in Cameroon in North Province along the border with Nigeria. Dialects are Demsa, Garoua, Jirai, Kobotachi, Malabu, Ndeewe, Ribaw, Wadi, and Zumu (Jimo). It is often considered the same language as Bacama.
Blench (2019) lists Bwatye (endonym: Ɓwaare; exonym: Bachama) as a closely related language variety. They are located in Adamawa State (Numan and Guyuk LGAs) and Kaduna State (northeast of Kaduna town). It is also called "Kwā ɓwàryē".
