Iran (word)
In Modern Persian, the word Īrān (ایران) derives immediately from 3rd-century Middle Persian Ērān (𐭠𐭩𐭫𐭠𐭭), initially meaning "of the Aryans" before acquiring a geographical connotation as a reference to the lands inhabited by the Aryans. In both the geographic and demonymic senses, Ērān is distinguished from the antonymic Anērān, literally meaning "non-Iran" (i.e., non-Aryan).
