Wikipedia:
The Swahili language, 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.[7] The closely related Comorian language, spoken in the Comoros Islands, is sometimes considered a dialect.

Although only around fifteen to fifty million people speak Swahili as their first language,[8] it is used as a lingua franca in much of Southeast Africa. Estimates of the total number of Swahili speakers vary widely, from 60 million to over 150 million.[9] Swahili serves as a national or official language of four nations: Tanzania, Kenya, Uganda and the Democratic Republic of the Congo. It is also one of the official languages of the African Union.

A significant fraction of Swahili vocabulary is derived from Arabic through contact with Arabic-speaking Muslim inhabitants of the Swahili Coast.[10] It has also incorporated German, Portuguese, English, Hindi and French words into its vocabulary through contact with empire builders, traders and slavers during the past five centuries.
