 The alphabet of Aramaic then seems to be based on the Phoenician alphabet, and there is a unity in the written language.It seems that in time, a more refined alphabet, suited to the needs of the language, began to develop from this in the eastern regions of Aram.The dominance of the Neo-Assyrian Empire under Tiglath-Pileser III over Aram-Damascus in the middle of the 8th century led to the establishment of Aramaic as a "lingua franca" of the empire, rather than it being eclipsed by Akkadian.
