'''Fog''' is a kind of [[mist]] or [[cloud]] that is at ground level. (Or sometimes, at [[sea level]], this is why [[ship]]s are sometimes equipped with [[foghorn]]s to warn other ships which can't see them because of the fog.) The word ''fog'' or ''foggy'' is also used [[metaphor]]ically to describe theories which are vague and unclear, as if in a real-world fog or mist.
