The West Germanic languages constitute the largest of the three branches of the Germanic family of languages (the others being the North Germanic and the extinct East Germanic languages).

The three most prevalent West Germanic languages are English, German, and Dutch. The family also includes other High and Low German languages and dialects including Luxembourgish and Yiddish, in addition to other Franconian and Ingvaeonic languages such as the Frisian languages, Scots and Afrikaans (which are closely related but separate from English and Dutch, respectively).
