Old South Arabian languages (distinct from the later attested Arabic) were spoken in the kingdoms of Dilmun, Meluhha, Sheba, Ubar, Socotra and Magan, which in modern terms encompassed part of the eastern coast of Saudi Arabia, and Bahrain, Qatar, Oman and Yemen. These languages (in the form of Ge'ez) later spread to the Horn of Africa circa 8th century BC.
