Proto-Semitic is the hypothetical proto-language ancestral to historical Semitic languages of the Middle East. Locations which have been proposed for its origination include northern Mesopotamia, the Arabian Peninsula, and the Levant with a 2009 study proposing that it may have originated around 3750 BCE. The Semitic language family is considered a component of the larger Afroasiatic macro-family of languages.
