休止 is a formal noun meaning 'pause' or 'cessation'—a temporary or complete stop in activity, sound, motion, or process. The character 休 (xiū) originally depicts a person resting under a tree and carries meanings of rest, pause, or cessation; 止 (zhǐ) means 'to stop' or 'to halt', often used in compound words to emphasize termination. Together, they form a literary or technical term that conveys a deliberate, often brief interruption—not just physical stillness but also the suspension of action, speech, or function.

This word appears frequently in music (e.g., a rest in notation), medicine (e.g., cardiac pause), literature (describing narrative breaks), and official documents. It is more formal than common alternatives like 暂停 or 中断 and rarely occurs in casual daily speech. Learners should note it’s not typically used for everyday pauses like 'taking a coffee break'—that would be 休息 instead.
