Matt, I appreciate that historians and other academics have skewed much terminology to fit a narrative. In many cases a fascist or racist one. But Sanscrit, the ancestral language of Hindi and Urdu,, is demonstrably related to ancient Persian, Greek, Latin, and Gothic.

"Iran" is Farsi for "Aryan". (The "Ire" in Ireland is thought to mean the same thing.) "Aryan" with 2 syllables is a popular given name among Hindu men. So Iranians and north Indians retain a tradition that they are descended from Aryan peoples.
