The Vietnamese word "gạn hỏi" is a verb that means "to press with questions" or "to question persistently." It involves asking someone questions in a way that encourages them to provide more detailed answers or to clarify information. This term is commonly used when someone is trying to get to the bottom of a matter or really understand something by asking multiple questions.
While "gạn hỏi" typically involves persistent questioning, it can also convey a sense of urgency or importance in the inquiries being made.
