Southwestern Mande languages Wikipedia
The Southwestern Mande languages are a branch of the Mande languages spoken in Sierra Leone, Guinea, and Liberia. There are around 2.8 million speakers, chiefly in Sierra Leone, due to Mende, the language with the most overall speakers. The Southwestern Mande languages are distantly related to the historic Manding languages, but are mutually unintelligble.
