Bacama language
Bachama is an Afro-Asiatic language of the Chadic branch that is spoken in Nigeria in Adamawa State principally in the Numan, Demsa and Lamurde Local Government Areas by the Bwatiye people. The Dialect spoken is KWA BWATIYE. There is Basa Pwa and Basa Voti and Njiya. The basa pwa accent is slightly different from that of bass Pwa and voti but all are the same people and tribe. Bachama is used as a trade language. It is often considered the same language as Bata.
