Who Are You ka Matlab in the Hindi language means “Aap Kaun Hain”, this word is usually used when you have met someone for the first time and do not know who they are. If so, you can tell him at that time that "Who Are You" I am not able to recognize you, please tell us something about yourself.

For example, suppose you have gone somewhere and suddenly someone comes who does not already know you, does not recognize you and asks you Who Are You. So it means he is asking you who are you I am not recognizing Please introduce yourself.
