The development of the Swahili language in Africa was largely influenced by the trade networks that connected the East African coast with Arab traders crossing the Indian Ocean. Arab traders played a significant role in the development of the Swahili language as they interacted with indigenous communities along the coast, leading to a blending of their languages and cultures. This resulted in the formation of Swahili as a unique language with a significant Arabic influence.
