Explanation:

After the conquest of Delhi (1192), Urdu was born out of the interaction of the Turkish settlers and soldiers in the barracks with the common people.Originally it was a dialect but slowly it acquired all the features of a formal language when the authors started using Persian script. It was further given an impetus by its use in Bahamani states of Ahmadnagar, Golkunda, Bijapur and Berar.Here it was even called dakshini or daccani (southern). As time passed, it became popular with the masses of Delhi.
