"علامت سوال" (question mark) is a punctuation mark used in writing to indicate a question. It is represented by the symbol "?" and is placed at the end of an interrogative sentence. This mark helps readers understand that the sentence is seeking information or clarification. In many languages, including اردو and انگلیسی, the question mark serves the same purpose. It is essential for effective communication, as it signals to the reader that a response or answer is expected. Proper use of the question mark enhances clarity in both spoken and written language.
