not true imo, probably an advantage coming from hindi.One of my brothers some how opted for urdu for.class 10th exams .
With just 3 months remaining that fellow was distressed .
He learned the language and passed the Urdu paper with good marks , highest in languages that is .
So if a average noob can learn Urdu in 3 months from scratch , it must not be a very hard language i guess .
I studied a bit of into classical arabic and its more documented, like what form a verb/noun is as a subject vs object etc.
I dont remember learning any such roles in urdu, during grade school. It was just absorbing from environment.
e.g.
kursian idhar lao ( bring the chairs here)
kursioon per baitho (sit on the chairs).
I cant tell you what rule is governing to use 1 form of plural of chairs vs the others.
If I switch the forms of plural in the above sentence, I would get laughed at as a noob, cos it is incorrect, but I dont know the rule governing that.
so I can imagine it being difficult for someone with no hindi/arabic/persian background.
