The Bantu-group languages of Mozambique that are indigenous to the country vary greatly in their groupings and in some cases are rather poorly appreciated and documented. Apart from its lingua franca uses in the north of the country, Swahili is spoken in a small area of the coast next to the Tanzanian border; south of this, towards Moçambique Island, Kimwani, regarded as a dialect of Swahili, is used. Immediately inland of the Swahili area, Makonde is used, separated farther inland by a small strip of Makhuwa-speaking territory from an area where Yao or ChiYao is used. Makonde and Yao belong to a different group, Yao being very close to the Mwera language of the Rondo Plateau area in Tanzania.
