|Nigeria, Niger, Chad, Central African Republic, Cameroon|
The Chadic languages are a branch of the Afroasiatic language family that is spoken in parts of the Sahel. They include 150 languages spoken across northern Nigeria, southern Niger, southern Chad, Central African Republic and northern Cameroon. The most widely spoken Chadic language is Hausa, a lingua franca of much of inland West Africa.
Newman (1977) classified the languages into four groups which have been accepted in all subsequent literature. Further subbranching, however, has not been as robust; Blench (2006), for example, only accepts the A/B bifurcation of East Chadic.
- West Chadic. Two branches, which include
- Biu–Mandara (Central Chadic). Three branches, which include
- (A) the Bura, Kamwe, and Bata languages, among other groups;
- (B) the Buduma and Musgu languages; and
- (C) Gidar
- East Chadic. Two branches, which include
Several modern genetic studies of Chadic speaking groups in the northern Cameroon region have observed high frequencies of the Y-Chromosome Haplogroup R1b in these populations (specifically, of R1b's R-V88 variant). This paternal marker is common in parts of West Eurasia, but otherwise rare in Africa.
