Proto-Indo-Iranian language

Proto-Indo-Iranian, also called Proto-Indo-Iranic or Proto-Aryan, is the reconstructed proto-language of the Indo-Iranian branch of Indo-European. Its speakers, the hypothetical Proto-Indo-Iranians, are assumed to have lived in the late 3rd millennium BCE, and are often connected with the Sintashta culture of the Eurasian Steppe and the early Andronovo archaeological horizon.
