Swahili

Swahili is a Bantu language spoken in Tanzania, Burundi, Congo (Kinshasa), Kenya, Mayotte, Mozambique, Oman, Rwanda, Somalia, South Africa, Uganda, UAE and the USA. Around 5 million people speak Swahili as a native language, and a further 135 million speak it as a second language. Swahili is an official language of Tanzania, Uganda and Kenya, and is used as a lingua franca throughout East Africa. The name Swahili comes from the Arabic word سَوَاحِل (sawāḥil), the plural of سَاحِل‏ (sāḥil - boundry, coast) and means "coastal dwellers". The prefix ki- is attached to nouns in the noun class that includes languages, so Kiswahili means "coastal language".
