Swahili, also known as Kiswahili, is a Bantu language and the first language of the Swahili people. It is a lingua franca of the African Great Lakes region and other parts of Southeast Africa, including Tanzania, Kenya, Uganda, Rwanda, Burundi, Mozambique, and the Democratic Republic of the Congo. The closely related Comorian language, spoken in the Comoros Islands, is sometimes considered a dialect.
