文法句型

toughen + object (rules, stance, policies)

toughen (no direct object)

用法筆記

When used transitively, the direct object is typically an abstract noun such as rules, policies, stance, regulations, or position — the subject makes those rules or positions stricter. When used intransitively, the subject (a situation, condition, or negotiation) itself becomes harsh or less flexible.

❌The situation toughened the government.
✅The government toughened its stance on immigration.
💡Sense 2 can take a direct object when it refers to rules, policies, or positions, but not when the object is a person or institution.
