Proto-Indo-Iranian language

Proto-Indo-Iranian or Proto-Indo-Iranic[1] is the reconstructed proto-language of the Indo-Iranian/Indo-Iranic branch of Indo-European. Its speakers, the hypothetical Proto-Indo-Iranians, are assumed to have lived in the late 3rd millennium BC, and are often connected with the Sintashta culture of the Eurasian Steppe and the early Andronovo archaeological horizon.

Proto-Indo-Iranian was a satem language, likely removed less than a millennium from its ancestor, the late Proto-Indo-European language, and in turn removed less than a millennium from the Avestan and Vedic Sanskrit of the Rigveda, its descendants.

Proto-Indo-Iranian has been considered to form a subgroup along with Greek, Armenian and Phrygian on the basis of many striking similarities in the morphological structure. However, this issue remains unsettled.[2]

It is the ancestor of the Indo-Aryan languages, the Iranian languages, and the Nuristani languages.
