×The bad news clouded over his judgment.
✓The bad news clouded his judgment.
'Cloud' 作為及物動詞時，意思是「使模糊」、「使蒙上陰影」，後面直接接受詞，不需要加 'over'。'Cloud over' 是不及物的片語動詞，主詞通常是天空或臉色。
×The mirror was clouding by steam.
✓The mirror was clouded by steam.

✓The misunderstanding clouded the relationship between them.
動詞 'cloud' 用於比喻「使（關係、判斷等）變差、變模糊」時，主語通常是抽象事物（如誤會、懷疑、情緒）。霧（fog）是具體事物，通常只會「cloud」具體的視線或鏡子，不會直接「cloud」抽象的關係。
