Mbum is a complex
dialect continuum consisting of several varieties.
ALCAM (2012) considers
Mbum,
Larang,
Pana and
Gbata to be four distinct but closely related languages. Pana (also spoken in Chad), Karang, Kali-dek and Kuo are eastern varieties that may be separate languages. To the south,
Gbata is spoken in the northern part of the arrondissement of
Bélabo in
Lom-et-Djerem department, Eastern Region. There, it is spoken in Woutchaba and Deng-Deng, located to the west and east of the
Sanaga River, respectively. Blench (2006) considers Gbete (Gbata) to be a separate language. The LiMbum is spoken to the South West especially in the Donga Mantung and around the Nkambe and Ndu Sub Divisions. ==Distribution==
