The Death of Imagination

OK, I just went and looked up Koine and Persian, and decided to delete my previous comment. I am curious about the "from Persian" designation for Indian languages, though: the histories of the Mughals that I've read seem to suggest that Persian influence became important in India during/because of the Mughal regime, but that's clearly not the case, and I wonder just how one draws a line between the Hindi-Urdu that emerged following Babur's invasion and the Persian-influenced languages that came before it - whether one can, actually, come up with a neat origin story for Hindi-Urdu that gives it two parents: one Persian, the other "Indian."
