Etymology

The word "madcap" originated in the late 16th century, combining "mad" (from Old English gemǣdd, meaning "insane" or "frenzied") and "cap" (referring to a head covering). The term likely evokes the image of someone whose "cap" (mind) is "mad"—suggesting reckless or whimsical behavior. Over time, it evolved to describe both impulsive actions and the people who embody them.
