Which term refers to a person who acts cautiously?

The term that refers to a person who acts cautiously is 'chary.' This word is often used to describe an individual who is careful about taking risks or making decisions, showing a sense of wariness or reluctance to engage in actions that may have negative consequences. An individual characterized as chary would typically take their time to evaluate situations, consider potential outcomes, and avoid unnecessary dangers. This cautious approach is particularly evident in contexts where the stakes are high, and acting without sufficient consideration could lead to adverse results.

In contrast, other terms such as 'casual' denote a lack of concern or serious thought, 'reckless' implies acting with disregard for the potential danger or consequences, and 'imprudent' suggests acting without thought for the future or without appropriate caution. Therefore, 'chary' is the best choice to describe someone who is deliberate and careful in their actions.
