The Nso are a people of the Grasslans region in the Northwest Province of Cameroon. Their traditional language is Lamnso (language of Nso) and their capital is Kumbo. Both the people and the capital are sometimes referred to as Banso (people of Nso) - the addition of the Ba prefix is attributed to the Fulani conquerors in the 17th century; the prefix resonates in the names of towns around the area.
