The nigéro-Congolese languages (or Niger-Congo according to the Anglo-Saxon terminology) constitute one of principal the families of languages of the world; it is most widespread of the groups of languages of Africa, in geographical extension, of many speakers and of many distinct languages. Almost all the languages of sub-Saharan Africa belong to this group. A frequent characteristic of the nigéro-Congolese languages is the use of a system of nominal kind.

Joseph Greenberg was the first to identify the zones where these languages were spoken, which it called “Niger - Congo” in a succession of articles published between 1949 and 1954. Little time before these articles were published in 1963 in a collection, it revised its classification by adding to it the Langues kordofaniennes like a subbranch of a more important group including the nigéro-Congolese languages. This family was renamed nigéro-kordofanienne. Simpleton and Sterk presented in 1977 a new classification based on the lexical statistics which leads to Bendor-Samuel classification in 1989. The languages kordofanniennes were classified there like a basic group, reintroducing the concept of nigéro-Congolese languages, term used nowadays among the linguists. Many classifications still consider the languages kordofaniennes as a branch very far away from the nigéro-Congolese languages, more for lack of evidence of membership that by the fact that these languages seem to form a group with share. Same manner, the mandé is often regarded as the second connects most distant.

The principal languages or sub-genera belonging to the nigéro-Congolese languages are:

• the Languages kordofaniennes spoken in the south about the Sudan, around the hills of Nubie
