It is a lingua franca of the African Great Lakes region and other parts of East and Southern Africa, including Tanzania, Uganda, Rwanda, Burundi, Kenya, some parts of Malawi, Somalia, Zambia, Mozambique, and the Democratic Republic of the Congo (DRC). Comorian, spoken in the Comoros Islands, is sometimes considered a dialect of Swahili, although other authorities consider it a distinct language. Sheng is a mixture of Swahili and English commonly spoken in Kenya and parts of Uganda. Swahili has a 16-20% Arabic loanwords in the language, including the word swahili, from Arabic sawāḥilī ( a plural adjectival form of an Arabic word meaning ‘of the coast’). The Arabic loanwords date from the contacts of Arabian traders with the Bantu inhabitants of the east coast of Africa over many centuries. Under Arab trade influence, Swahili emerged as a lingua franca used by Arab traders and Bantu peoples of the East African Coast.
