High Quality Content by WIKIPEDIA articles! The Ubangian languages form a fairly close-knit language family of some seventy languages centered on the Central African Republic. They are the predominant languages of the CAR, spoken by 2 3 million people, and include the national language, Sango. Although the family is clear-cut, and consists of half a dozen coherent branches, the interrelationships of these branches are not so straightforward. Ethnologue agrees on the Sere-Mba node, and calls the Gbaya languages "Gbaya-Manza-Ngbaka". Note the name Ngbaka is used for languages in different branches of the family.
