問題
もんだい · mondai · JLPT N5 · noun
problem
❓ 問題 = ask (問) + topic (題): a topic that asks for an answer
問 means to ask and 題 means topic or title (as in 宿題, homework). A mondai is literally a question-topic, which is why it covers both an exam question and a problem to solve. Sound hook: Monday = mondai, the problem day.
