How to distinguish Arbi and Farsi words used in urdu ?

Re: How to distinguish Arbi and Farsi words used in urdu ?

Tashakur is also Farsi but its used in Dari (Afghani Farsi) whereas the Iranians prefer using Merci. As for turkis i've heard that the word Urdu itself is Turkish is that true? Urdu has a few letters that are not in any of the languages of the middle east like dhaay (its like a ray but with a toi looking thing on it) I've tried ot have people pronounce that word and its virtually impossible for them, like saying Gari (car) the letter used in it is pretty unique to the languages of the subcontinent, including South Asian languages and those of Sri Lanka like Telegu and Tamil
