cloudy + noun (water / liquid / juice / glass)

用法筆記

Frequently used to describe liquids that have gone bad (juice, milk) or containers that have become dirty or aged (glass, aquarium). Does not usually describe large bodies of water like oceans — 'murky' is more natural there.

常見錯誤

❌The river was cloudy after the storm.
✅The river was murky after the storm.
💡'murky' is the preferred word for large natural bodies of water.
❌The window is cloudy with fingerprints.
✅The window is smudged with fingerprints.
💡'cloudy' implies an overall loss of transparency, not temporary marks.

memory ... is cloudy — common pattern with recall nouns

The details of the contract are still cloudy, so Leila asked the lawyer to explain each point.

details ... are still cloudy — used with information nouns

同義詞
  • vague

    more common and neutral; can be used both before and after a noun

  • unclear

    more direct; works in both attributive and predicative positions

  • hazy

    suggests something is distant or seen through a fog in the mind

  • fuzzy

    informal; like a blurry photograph or a confused recollection

反義詞

文法句型

memory / thought / idea + be + cloudy

details / future / plan + remain + cloudy

explanation / answer + seem + cloudy

用法筆記

Only used predicatively (after 'be', 'remain', 'seem') — you cannot say 'a cloudy idea' in standard English. This sense is less common than 'vague' or 'unclear' and tends to sound slightly literary or figurative.

常見錯誤

❌He gave a cloudy explanation.
✅His explanation was cloudy.
💡This sense is predicative only; do not place 'cloudy' before the noun.
❌My understanding is very cloudy about this topic.
✅My understanding of this topic is cloudy.
💡Use 'of' to connect the topic, not 'about'.
