命题 (mìng tí) literally combines 命 (mìng, 'to command' or 'to appoint') and 题 (tí, 'topic', 'subject', or 'question'). Together, it means 'to formulate a topic' or 'to set questions' — especially in academic, testing, or research contexts. As a verb, it refers to the act of designing exam questions or defining a research problem; as a noun, it refers to the question(s) themselves or the topic assigned for discussion or writing.

This word is most commonly used in formal educational settings: teachers 命题 for exams, professors 命题 for thesis topics, and standardized testing authorities issue official 命题. It carries a sense of authority and intentionality — the 'setter' determines scope, difficulty, and focus. While occasionally used metaphorically (e.g., 'to propose a philosophical question'), its core domain remains education, assessment, and scholarly work — not casual conversation.
