The common ancestor of all of the languages in this family is called
Proto-Indo-Iranian—also known as Common Aryan—which was spoken in approximately the late 3rd millennium BC. The three branches of the modern Indo-Iranian languages are
Indo-Aryan,
Iranian, and
Nuristani. A fourth independent branch,
Dardic, was previously posited, but recent scholarship in general places Dardic languages as archaic members of the Indo-Aryan branch.
