"답변, 답, 대답" 답 means "answer". All three words all share this theme. - 답: answer, solution - both the verbal kind and a solution to a problem. - 답변: (변: speech, talk, argument) *verbal* answer / response. (more formal) - 대답: (대: face, toward) answer / reply *to* a question or request. Some examples: - 이 문제의 답은 무엇입니까?: What is the answer [solution] to this question. - 장관은 기자의 질문에 답변하였다: The minister gave an answer to the reporter's question. - 선생님이 질문하면 곧 대답하거라: Answer immediately if the teacher asks a question.
