Boko language

Boko, or Boo, is a Mande language of Benin and Nigeria.

Names
Boko is the best-known name of this language, but it is also known as Boo or by its Hausa exonym Busanci (also spelled Busanchi, Bussanci or Bussanchi).

The Boko people are one of two subgroups of the Bissa people, the other being the Busa people, who speak the Busa language. They are not a clan but a subgroup. They are neighbors to the Bariba people, who speak the Bariba language, a Gur language. The Bissa people proper speak the Bissa language, which is closely related to Boko.
