Definition

Careful to avoid danger, mistakes, or unnecessary risk.

If someone is cautious, they think carefully before acting and try to prevent problems. They often move slowly, check details, and avoid taking risks without good reasons. Being cautious can be sensible, but it can also mean hesitating when others would act more quickly.

Examples
