The Bambukic 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. Their unity is not accepted by Güldemann (2018).[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. Subclassification follows Blench (2004).[4]
The Waja languages were once thought to belong to this group, but are now placed with the Kam language. (See Adamawa languages.)
