同義詞

  • responsibility

    More neutral and formal; can be positive or negative, while 'fault' is always negative.

  • guilt

    Stronger, implying moral or legal wrongdoing; more serious than 'fault'.

反義詞
  • credit

    Recognition for something good, the opposite of blame or fault.

用法筆記

Often appears in fixed expressions: 'be someone's fault' (informal, daily speech) or 'be at fault' (slightly more formal). 'Admit fault' is a formal collocation used in legal or business contexts.

常見錯誤

The mistake is my wrong.
The mistake is my fault.
💡'fault' is the noun for responsibility, not 'wrong'.
I made a fault.
I made a mistake.
💡'fault' as a count noun means a defect or character flaw, not a simple error. Use 'mistake' for everyday errors.

常見錯誤
