My teacher mentioned once that Urdu actually means 'lashkar' ie army, and it was sort of a mish-mash between different languages.

Here is an excerpt from Wikipedia.

Urdu means "camp" in the Persian language; and Urdu language was the language of the camp when "Nader Shah" of Persia (Iran) invaded India. "Nader Shah" set up his camp in what is now modern day Pakistan, and from here the Hindi speaking Indians and the Persian (Iranian Dialect: Parsi) speaking Iranians (Persians) mingled together and a third language, Urdu was born. It is bridge between the two branches of Indo-Iranian language. Today Urdu has adapted a lot of Arabic and Persian (Farsi) words in it because of many migrants from Iran and the Middle East adapted this language. It is also very welcoming to other international languages; it has adopted certain vocabulary from English. This is surely a sign of Allah, how a 'camp' language ends up being one of the most beautiful language in the world!
