文法句型

a convinced + noun (e.g. socialist, vegetarian, atheist)

用法筆記

Distinguish from sense 1: this sense is attributive (placed before a noun naming a belief or movement, like 'vegetarian' or 'Catholic'), not predicative. The noun must name an ideology or commitment, not a feeling.

常見錯誤

❌He is a convinced that vegetables are healthy.
✅He is a convinced vegetarian.
💡this sense needs a noun naming a belief or movement after 'convinced'.
