The name "Irān", meaning "land of the Aryans", is the New Persian continuation of the old genitive plural aryānām (proto-Iranian, meaning "of the Aryans"), first attested in the Avesta as airyānąm (the text of which is composed in Avestan, an old Iranian language spoken in northeastern Greater Iran, or in what are now Turkmenistan and Tajikistan).[3][4][5][6]
The Modern Persian word Īrān (ایران) derives immediately from Middle Persian Ērān (Pahlavi spelling: ʼyrʼn), first attested in an inscription that accompanies the investiture relief of the first Sassanid king Ardashir I at Naqsh-e Rustam.[7] In this inscription, the king's Middle Persian appellation is ardašīr šāhān šāh ērān while in the Parthian language inscription that accompanies the Middle Persian one the king is titled ardašīr šāhān šāh aryān (Pahlavi: ... ʼryʼn) both meaning king of kings of Iranians.[citation needed]
