 Those that live in the Usambara call their language Dahisu and call themselves Segeju.The name Segeju is said to derive from the Swahili words "Kusega", meaning 'to draw' and "juu", meaning 'up' or 'high'.The Segeju were said to have acquired the name following contact with the Shirazi Arabs in the 17th century, on account of the habit of their wearing of skin garments around their loins higher than was usual.
