Indo-Iranian language

The Indo-Iranian language group constitutes the easternmost extant branch of the Indo-European family of languages. It consists of four language groups: the Indo-Aryan, Iranian, Nuristani, and Dardic. The term Aryan languages is also used to refer to the Indo-Iranian languages . The speakers of the Proto-Indo-Iranian language, the hypothetical Proto-Indo-Iranians, are usually associated with the late 3rd millennium BC Sintashta-Petrovka culture of Central Asia. Their expansion is believed to have been connected with the invention of the chariot.
