'措施' (cuò shī) is a formal noun meaning 'measure' or 'countermeasure' — a specific action or plan taken to address a problem, achieve a goal, or respond to a situation. The character 措 (cuò) originally meant 'to handle' or 'to manage', and 施 (shī) means 'to implement' or 'to carry out'; together, they emphasize deliberate, organized action rather than spontaneous response.

This word is commonly used in official, academic, or professional contexts — especially in policy announcements, public health guidance, environmental protection plans, or corporate strategy. It often appears with modifiers like '有效' (effective), '必要' (necessary), or '紧急' (emergency), and frequently follows verbs like '采取' (to adopt/take) or '实施' (to implement). While it can refer to any planned action, it carries a tone of seriousness and intentionality, rarely appearing in casual daily conversation.
