How it's used

Focuses on the mental state of being alert or vigilant, rather than just physical caution. It often implies keeping one's eyes or ears open to avoid missing details or making mistakes. While it can be used as a verb, it is frequently used as an adjective to describe someone's attitude or performance.

Examples

Remember to be careful when crossing the road.
You are so inattentive at work, it is easy for accidents to happen.

Common phrases

not attentive enough

Common mistake

Do not confuse this with 小心, which is more commonly used for physical safety or avoiding danger. 留神 carries a stronger nuance of paying attention to details or being mentally present.
