Mbum language

Mbum Proper (also Mboum, Buna, Mboumtiba and Wuna) is a Adamawa–Ubangi language of Central Africa. It is spoken by about people in Cameroon and the Central African Republic.

History
The Mbum language is spoken by the Mbum people who inhabit Cameroon, the Central African Republic, and Chad. While their origins are unclear, some believe that the Mbum were one of the earliest ethnic groups of the Adamawa Region.

The Mbum people have such a close relationship with the Dii people, and one which has persisted for so long, that outsiders often have a hard time distinguishing them. In the early nineteenth century, both groups came under the rule of the Fulani Muslims, who they are said to have intermarried in large numbers. Despite this, the Mbum and Dii peoples still managed to hold on to their traditional spiritual beliefs until the twentieth century. The Mbum converted to Islam, while the Dii converted to Christianity.

Varieties
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.
