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 (to the north of Jalingo 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 (2018) suggests that Bikwin and Jen could form separate groups.
