This is a present perfect tense question in Urdu, used to ask whether a letter has been written by someone (male) with relevance to the present moment. It implies an expectation or curiosity about the completion of the action. The word "خط" (khat) means "letter" or "correspondence," and "لکھا ہے" (likha hai) indicates the action is done but its effect (e.g., the letter exists now) continues. Commonly used in daily conversations to confirm tasks or follow up on communication.
