用法筆記

In this sense, complain does not take a direct object. You complain to someone (the person you tell) and about something (the reason). A that-clause can replace about + noun: 'He complained that the soup was cold' means the same as 'He complained about the cold soup.'

常見錯誤

❌She complained me that the food was cold.
✅She complained to me that the food was cold.
💡The preposition 'to' is needed before the person you are telling.
❌He complained for the poor service.
✅He complained about the poor service.
💡Use 'about' not 'for' when stating the reason for the complaint.
❌I complained him to the manager.
✅I complained to the manager about him.
💡Cannot use a direct object; restructure with 'to' and 'about'.

    to officially praise someone or something

文法句型

complain + to + organization/authority + about + noun

complain + against + person/organization

complain + that-clause (formal)

用法筆記

Distinguish from sense 1: this sense implies a formal process — you expect an authority to investigate or resolve the problem. Unlike sense 1, it can be used with against ('complain against the manufacturer'). In written official contexts, lodge a complaint or file a complaint are more common alternatives.

常見錯誤

❌I complained the company for bad service.
✅I lodged a complaint against the company for poor service.
💡The formal sense still cannot take a direct object; 'lodge/file a complaint against' is the standard pattern.
❌He complained to the committee with corruption.
✅He complained to the committee about corruption.
💡Use 'about' (not 'with') for the issue being reported.
