Masalit (autonym kana masara) is a Maban language spoken by the Masalit people in western Darfur. It has two sociolects: "heavy" Masalit, with a complicated agglutinative grammar, spoken by higher-ranking people and in the countryside, and "light", spoken particularly in the home and in the market, with a somewhat simplified grammatical structure and many borrowings from Sudanese Arabic, the regional lingua franca and language of education.
