Wiki: The term Iran derives directly from Middle Persian Ērān, first attested in a third-century inscription at Rustam Relief, with the accompanying Parthian inscription using the term Aryān, in reference to the Iranians.[42] The Middle Iranian ērān and aryān are oblique plural forms of gentilic nouns ēr- (Middle Persian) and ary- (Parthian), both deriving from
Proto-Iranian *arya- (meaning "Aryan", i.e. "of the Iranians"),[42][43] recognized as a derivative of Proto-Indo-European *ar-yo-, meaning "one who assembles (skilfully)"
