Semite, member of a people speaking any of a group of related languages presumably derived from a common language, Semitic (see Semitic languages). The term came to include Arabs, Akkadians, Canaanites, Hebrews, some Ethiopians, and Aramaean tribes. Mesopotamia, the western coast of the Mediterranean, the Arabian Peninsula, and the Horn of Africa have all been proposed as possible sites for the prehistoric origins of Semitic-speaking peoples, but no location has been definitively established.
So- who is right? You or the definition?
