Yasa language

Iyasa (Yasa, Yassa) is a Bantu language spoken in Cameroon and Equatorial Guinea by the Iyasa and Ndowe coastal fishing peoples. It is also spoken by Pygmies, perhaps Babongo, in Gabon. Approximately 3,000 people speak Iyasa, though some note that this number may be an overestimation.

Iyasa also goes by the names Bongwe, Lyaasa, and Maasa. Dialects are Bweko, Vendo, Bodele, Marry, One, Asonga, Bomui, Mogana, Mooma, Mapanga. It may in turn be a dialect of Kombe. Speakers report that Kombe and Iyasa are almost perfectly mutually intelligible.
