尼日尔-刚果语系
The Niger–Congo languages constitute the largest language family spoken in West Africa and perhaps the world in terms of the number of languages. One of its salient features is an elaborate noun class system with grammatical concord. A large majority of languages of this family are tonal such as Yoruba and Igbo, Akan and Ewe language. A major branch of Niger–Congo languages is the Bantu phylum, which has a wider speech area than the rest of the family (see Niger–Congo B (Bantu) in the map above).
