Swahili

Swahili, also known as Kiswahili, is a Bantu language originally spoken by the Swahili people, who are found primarily in Tanzania, Kenya, and Mozambique (along the East African coast and adjacent littoral islands). Estimates of the number of Swahili speakers, including both native and second-language speakers, generally range from 150 million to 200 million. Most native speakers reside in Tanzania and Kenya.

Around 40% of Swahili vocabulary consists of Arabic loanwords, including the name of the language ( , a plural adjectival form of an Arabic word meaning 'of the coasts'). Swahili also has a significant number of loanwords from Portuguese, English and German. The Arabic loanwords date from the era of contact between Arab slave traders and the Bantu inhabitants of the east coast of Africa, which was also the time period when Swahili emerged as a lingua franca in the region.
