Urdu Language is the mixture or we can say a combination of different languages. Urdu is mostly engendered by Persian language.
Even though, the word “Urdu” itself is not a Persian word, it is gleaned from the Turkic word ordu (army) or orda which means “Lashkar”.
However, national anthem of Pakistan is in Persian language and consist of only one urdu word, i.e “Ka”, which is used in the sentence as Pak Sir Zameen “Ka” Nizam.
