Oti–Volta languages
The Oti–Volta languages form a subgroup of the Gur languages, comprising about 30 languages of northern Ghana, Benin, and Burkina Faso spoken by twelve million people. The most populous language is Mõõré, the national language of Burkina, spoken by five million people.
The family is named for the Oti and Volta rivers.Languages
The internal classification of Oti–Volta, as worked out by Gabriel Manessy 1975–79 and Naden 1989 is as follows:
Native Dagbani speakers assert that Dagbani is mutually intelligible with Dagaare, Frafra, Mamprusi, and Wali, but in the case of Dagaare, Frara and Wali it is rather the case that many people can understand some of a language which is not their mother tongue. These languages are not mutually intelligible with Mõõré or Kusaal.
