[3] According to one of the newest updates to the Bantu classification system,[4] other languages belonging to this subgroup are: Pol (A92a), Pɔmɔ (A92b), Kweso (A92C) and Kakɔ (A93).
[5] Kwakum is mainly spoken in the East region of Cameroon, southwest of the city Bertoua.
Kwakum is listed by Simons & Fennig[6] as having three dialects: Til, Beten (or Mbeten, or Petem), and Baki (or Mbaki).
The Betán (or Til), who occupy three villages in the commune of Dimako (Longtimbi, Kpaktala, and Siafum) came from the north, from the village of Mbeten where Betán is still spoken - in the vicinity of Pol, north of Bertoua (Pol canton, commune of Bélabo and Diang, department of Lom-et-Djerem, Eastern Region).
David Hare completed an MA thesis entitled Tense in Kwakum Narrative Discourse in June 2018.
