Northwest Semitic is a division of the Semitic languages comprising the indigenous languages of the Levant. It emerged from Proto-Semitic in the Early Bronze Age. It is first attested in proper names identified as Amorite in the Middle Bronze Age. The oldest coherent texts are in Ugaritic, dating to the Late Bronze Age, which by the time of the Bronze Age collapse are joined by Old Aramaic, and by the Iron Age by Sutean and the Canaanite languages.

The Semitic languages are a branch of the Afroasiatic language family. They include Arabic, Amharic, Aramaic, Hebrew, and numerous other ancient and modern languages. They are spoken by more than 330 million people across much of West Asia, North Africa, the Horn of Africa, Malta, and in large immigrant and expatriate communities in North America, Europe, and Australasia. The terminology was first used in the 1780s by members of the Göttingen school of history, who derived the name from Shem, one of the three sons of Noah in the Book of Genesis.
