 The last Akkadian inscriptions date from the late first century AD, and cuneiform script in the second century AD, both in Mesopotamia.By the late third millennium BC, East Semitic languages such as Akkadian and Eblaite, were dominant in Mesopotamia and north east Syria, while West Semitic languages, such as Amorite, Canaanite and Ugaritic, were probably spoken from Syria to the Arabian Peninsula, although Old South Arabian is considered by most people to be a South Semitic language despite the sparsity of data.The Akkadian language of Akkad, Assyria and Babylonia had become the dominant literary language of the Fertile Crescent, using the cuneiform script that was adapted from the Sumerians.
