Bikwin–Jen languages

The Bikwin–Jen or simply the Jen languages form a branch of the Adamawa family. They are spoken in and around Karim Lamido LGA in Taraba State, and in other nearby states of eastern Nigeria.
Bikwin-Jen may not necessarily be a coherent group. Due to the internal diversity of Bikwin-Jen, Guldemann suggests that Bikwin and Jen could form separate groups.
