foggy

Meaning

Adjective

• Obscured by mist or fog; unclear; hazy
• Confused, befuddled, etc.
• Being, covered with, or pertaining to fog

Origin

• From fog + -y, originally in the sense "covered with tall grass; marshy; thick". It is not clear whether fog is a back-formation from foggy or has a separate Germanic origin, and hence whether foggy and foggy represent one word or two. See fog ("mist"; "tall grass") for more.
