The term "Semitic" literally refers to the descendants of Shem, the son of Prophet Noah (peace be upon him). Abraham (peace be upon him) is recognized by history to be a descendant of Shem, and in turn all of his descendants are traditionally called Semites, including the Jews and the Arabs.
In today’s discourse, Semitic is used to designate a linguistic group within the larger Afro-Asiatic language family.
People who speak these languages are often referred to as Semitic people. These languages include Arabic, Hebrew, Amharic (in Ethiopia), and a number of other languages.
