Pakistani Language (Urdu)
Urdu in Persian (Pārsi) means camp and "Urdu" language was the language of the camp. When Nader Shah invaded India he set up his camp in modern day Pakistan, here the Hindi speaking Indians and the Pārsi (Persian) speaking Iranians (Persians) mingled together and a third language Urdu was born. It is bridge between the two branches of Indo Iranian languages. Today, Urdu has a lot of Arabic words in it. 

So it "IS" laughable when Pakistanis claim everything for themselves.

By the way, are you Persian?
