Trans-Benue or Yungur–Jen languages form a proposed branch of the provisional Savanna languages, a reduced form of the Waja–Jen branch of the old Adamawa languages family (G7, G9, G10).
They are spoken in north eastern Nigeria.
[1] Bennett (1983) had also proposed a Trans-Benue group consisting of the Burak-Jen (i.e., Bikwin-Jen), Yungur (i.e., Bena-Mboi), and Tula-Longuda subgroups.
[2] Blench (2006) groups the Yungur (G7), Bikwin–Jen (G9), and Longuda (G10) languages together within part of a larger Gur–Adamawa language continuum.
[3] Kleinewillinghöfer (1996) notes the affinities of the Bikwin languages, which were unknown to Greenberg, with the Jen languages.
