Ek Bhasha, Do Likhawat

Re: Ek Bhasha, Do Likhawat

I was thinking of Ghalib but he was in the 1800s, oldest was Amir khusrau who was in 1200s. Was there Hindi at that time? As its or sure what ever language would exist at that time would have had Persian influence and hence can be called today’s Urdu.
