Definition

A thick cloud of very small water drops in the air near the ground that makes it hard to see. It can also be used as a verb meaning to cover or fill something with this mist.

Usage & Nuances

Usually uncountable: we say 'thick fog' or 'a patch of fog,' not usually 'a fogs.' Common collocations: 'dense fog,' 'foggy morning,' 'fog rolled in.' As a verb, 'fog up' is common for windows or glasses. Don't confuse it with 'mist,' which is usually lighter.
