The Eastern Mande languages (called Eastern Eastern Mande by Kastenholz, and NigerâÂÂVolta by Schreiber and also known as the BisaâÂÂBusa languages) are a branch of the Mande languages spoken in seven areas: northwest Burkina Faso, the border region of northern Benin and Nigeria, and one language, Bissa, also spoken in Ghana, Togo, and Ivory Coast and the Samo languages also spoken in Mali.
The following internal classification is from Dwyer (1989, 1996), as summarized in Williamson & Blench 2000.
Vydrin (2009) places San (Samo) with Bisa.
