Swahili
A Bantu lingua franca with significant Arabic influence.
Swahili, also known as Kiswahili, is a Bantu language within the Atlantic–Congo family, originally spoken by the Swahili people along the East African coast and nearby islands, chiefly in Tanzania, Kenya, and Mozambique. Estimates of total speakers, including native and second-language users, broadly range from 40 million to 200 million, with most native speakers living in Tanzania and Kenya. The language’s vocabulary is notably shaped by Arabic, with about 40% of its words derived from Arabic, including its own name, which comes from an Arabic plural adjectival form meaning “of the coasts.” These Arabic loanwords date from the era of contact between Arab slave traders and Bantu inhabitants, a period when Swahili emerged as a regional lingua franca. Additional loanwords come from Portuguese, English, and German. The core of Swahili originates in Bantu languages of the East African coast, with cognates in Unguja, Pemba, and Mijikenda languages. While some sources cite 16–20% of vocabulary as loanwords—mostly Arabic, with contributions from Persian, Hindustani, Portuguese, and Malay—other analyses using daily word lists show 72–91% inherited from the Sabaki parent language, with only 2–8% from non-African languages. Omani Arabic is the primary source of Arabic borrowings. The earliest known Swahili documents are letters from Kilwa, Tanzania, written in 1711 in Arabic script and preserved in Goa, India. Swahili was originally written in Arabic script, later replaced by a Latin alphabet introduced by Christian missionaries and colonial administrators. Today, it is an official language of the East African Community, alongside English and French, and a working language of the African Union and the Southern African Development Community. The East African Kiswahili Commission, established in 2015, promotes and coordinates the language’s development for regional integration. In 2022, the United Nations declared July 7 as Swahili Language Day, commemorating Julius Nyerere’s adoption of Swahili for Tanganyikan independence struggles. Shikomor, spoken in Comoros and Mayotte, is closely related and sometimes considered a dialect.

Lore & Background
Swahili originated from Bantu languages of the East African coast, with substantial Arabic loanwords dating from the era of contact between Arab slave traders and Bantu inhabitants. About 40% of its vocabulary is derived from Arabic, including the name 'Swahili' itself, which comes from an Arabic word meaning 'of the coasts'. The language also contains loanwords from Portuguese, English, German, Persian, Hindustani, and Malay. Historical linguists note that while Arabic influence is significant, the core grammar and much basic vocabulary remain inherited from the Sabaki branch of Bantu languages.
