Ge'ez language
Old South Arabian languages (classified as South Semitic and therefore distinct from the Central Semitic language of Arabic which developed over 1000 years later) 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. South Semitic languages are thought to have spread to the Horn of Africa circa 8th century BC where the Ge'ez language emerged (though the direction of influence remains uncertain).
