反義詞

文法句型

unexplained + noun

remain / go + unexplained

用法筆記

Frequently pairs with nouns like disappearance, death, phenomenon, or occurrence. Often follows remain or go to indicate an ongoing lack of explanation (e.g. 'the reason remains unexplained', 'the event went unexplained'). Distinguish from unexplainable: unexplained means 'not yet explained' (a cause likely exists but hasn't been found), whereas unexplainable means 'impossible to explain or understand'.

常見錯誤

❌The cause of the fire remains unexplainable.' (when you mean it hasn't been found yet).
✅The cause of the fire remains unexplained.
💡'unexplained' means no explanation has been given yet; 'unexplainable' means it cannot be explained at all.
❌The disappearance was unexplainedly strange.
✅The disappearance was unexplained and strange.
💡'unexplained' is an adjective, not an adverb; the word 'unexplainedly' is non-standard.
