The development of the Swahili language in Africa was primarily influenced by the blending of indigenous Bantu languages with Arabic as a result of extensive trade relationships along the coast of East Africa and across the Indian Ocean. Arab traders conducted trade along the Swahili Coast, bringing their language and culture with them, which eventually led to the development of Swahili as a distinct language.
