Kwah (Kwa), also known as Baa (Bàː), is a Niger–Congo language of uncertain affiliation; the more it has been studied, the more divergent it appears. Joseph Greenberg counted it as one of the Bambukic languages of the Adamawa family. Boyd (1989) assigned it its own branch within Waja–Jen. Kleinewillinghöfer (1996) removed it from Waja–Jen as an independent branch of Adamawa. When Blench (2008) broke up Adamawa, Kwah became a provisional independent branch of his larger Savannas family. Baa traditional religion has two main deities, Gbandima and Kassimin.
