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.

The Afroasiatic languages, also known as Hamito-Semitic or Semito-Hamitic, are a language family of about 400 languages spoken predominantly in West Asia, North Africa, the Horn of Africa, and parts of the Sahara and Sahel. Over 500 million people are native speakers of an Afroasiatic language, constituting the fourth-largest language family after Indo-European, Sino-Tibetan, and Niger–Congo. Most linguists divide the family into six branches: Berber, Chadic, Cushitic, Egyptian, Semitic, and Omotic. The vast majority of Afroasiatic languages are considered indigenous to the African continent, including all those not belonging to the Semitic branch.
