Unlike Sense 1, which describes a person's general mental ability, this sense describes the result of thinking — a decision, analysis, question, or choice. The thing itself shows careful thought rather than the person being generally smart.

常見錯誤

❌She is an intelligent judge, so everyone respects her.
✅The judge's intelligent ruling earned everyone's respect.
💡For sense 2, describe the outcome (ruling/decision), not the person in general. Use sense 1 for describing a person's overall ability.
❌He made an intelligent guess without any information.
✅He made an intelligent guess based on the available data.
💡This sense implies thought and reasoning; if no information or logic was used, 'lucky' or 'wild' is more appropriate.
