抓紧 (zhuā jǐn) is a compound verb meaning 'to seize firmly' or 'to make good use of (time/opportunity)' — literally combining 抓 (to grab, grasp) and 紧 (tight, firm). It emphasizes urgency, efficiency, and active effort: not just holding something, but holding it securely and purposefully. The word often implies acting quickly before time runs out or an opportunity disappears.

This verb is commonly used in contexts involving time management, work deadlines, study, or urgent tasks — for example, '抓紧时间' (make good use of time) or '抓紧机会' (seize the opportunity). It carries a tone of encouragement or mild pressure, frequently appearing in advice, instructions, or self-motivation. While it can be used literally (e.g., grabbing a railing), its figurative use — especially with abstract nouns like 时间, 机会, or 工作 — is far more frequent in everyday speech and writing.
