多雾的用英语可以说是 foggy。来源是由 Middle English fogge, from Old English fog, ultimately from a Germanic root. 例句：

It was a foggy morning, so I couldn't see very far in front of me.（那是一个多雾的早晨，所以我看不到前面很远。）

The weather forecast said that it would be foggy tonight, so I decided to stay home.（天气预报说今晚会多雾，所以我决定呆在家里。）
