How it's used

Describes someone who possesses a quick, intuitive sense for danger or subtle shifts in their environment. It implies a high level of mental alertness rather than just physical speed. People often use this to praise someone for their street smarts or their ability to handle unexpected crises without panicking.

Examples

He is sharp; he left immediately once he saw something was wrong.
You are so astute, you will definitely be able to avoid this trap.

Common phrases

quick-witted reaction
more vigilant than others

Common mistake

Do not confuse this with 醒目, which is a broader term for being clever or smart in a general sense. 機警 specifically emphasizes the ability to detect threats or changes, making it more situational and reactive.
