Benue–Congo languages in the context of "Volta–Congo"

The Efik are an ethnic group located primarily in southern Nigeria, and western Cameroon. Within Nigeria, the Efik can be found in the present-day Cross River State. The Efik speak the Efik language which is a member of the Benue–Congo subfamily of the Niger-Congo language group. The Efik refer to themselves as Efik Eburutu, Ifa Ibom, Eburutu and Iboku.

The bulk of the Efiks can be found in Calabar and the southern part of Cross River State. Prior to 1905, Old Calabar was a term used to describe the Efik settlements of Duke Town, Creek Town, Old town, Cobham town, Henshaw town, Adiabo and Mbiabo (consisting of Mbiabo edere, Mbiabo Ikot Offiong and Mbiabo Ikoneto). The Efik have also been referred to as "Calabar people" in historical literature. The term "Calabar people" was particularly popular prior to the nineteenth century and was synonymous with the Efik.

The Volta–Niger family of languages, also known as West Benue–Congo or East Kwa, is one of the branches of the Niger–Congo language family, with perhaps 70 million speakers. Among these are the most important languages of southern Nigeria, Benin, Togo, and southeast Ghana: Yoruba, Igbo, Bini, and Gbe.

These languages have variously been placed within the Kwa or Benue–Congo families or, starting in the 1970s, combined with them altogether. Williamson & Blench (2000) separate the languages here called Volta-Niger from the others. Güldemann (2018) fails to see clear criteria for dividing the languages into two or three families and maintains the broad grouping and name of Benue-Kwa for all them.
