Swahili

Swahili (also called Kiswahili) is a Bantu language widely spoken in East Africa, Earth. Swahili is the mother tongue of the Swahili people who inhabit a 1,500 kilometers (931.5 miles) stretch of the East African coast from southern Somalia to northern Mozambique. It is spoken by over 50 million people, of whom there are approximately five million first-language speakers and thirty to fifty million second-language speakers. Swahili has become a lingua franca for East Africa and surrounding areas.

It is a secondary language of the UNSC. Though it is widely spoken in its native areas around the modern East African Protectorate, Swahili's use is being gradually diminished as universal English is being accepted throughout the UNSC.
