The Chadic languages form a branch of the Afroasiatic language family. They are spoken in parts of the Sahel. They include 196 languages spoken across northern Nigeria, southern Niger, southern Chad, and northern Cameroon. By far the most widely spoken Chadic language is Hausa, a lingua franca of much of inland Eastern West Africa, particularly Niger and the northern half of Nigeria. Hausa, along with Mafa and Karai Karai, are the only three Chadic languages with more than 1 million speakers.

Composition

Paul Newman (1977) classified the languages into the four groups which have been accepted in all subsequent literature. Further subbranching, however, has not been as robust; Roger Blench (2006), for example, only accepts the A/B bifurcation of East Chadic. Subsequent work by Joseph Lovestrand argues strongly that Kujarge is a valid member of East Chadic. The placing of Luri as a primary split of West Chadic is erroneous. Bernard Caron (2004) shows that this language is South Bauchi and part of the Polci cluster. A suggestion for including the language isolate Kujargé as an early-diverged member, which subsequently became influenced by East Chadic, has been made by Blench (2008).

Loanwords

Chadic languages contain many Nilo-Saharan loanwords from either the Songhay or Maban branches, pointing to early contact between Chadic and Nilo-Saharan speakers as Chadic was migrating west. Although Adamawa languages are spoken adjacently to Chadic languages, interaction between Chadic and Adamawa is limited.
