WORD HISTORY: Giddy

The word giddy refers to fairly lightweight experiences or situations, but at one time it had to do with profundities. Giddy can be traced back to the same Germanic root *gud- that has given us the word God. The Germanic word *gudigaz formed on this root meant "possessed by a god." Such possession can be a rather unbalancing experience, and so it is not surprising that the Old English descendant of *gudigaz, gidig, meant "mad, possessed by an evil spirit," or that the Middle English development of gidig, gidi, meant the same thing, as well as "foolish; mad (used of an animal); dizzy; uncertain, unstable." Our sense "lighthearted, frivolous" represents the ultimate secularization of giddy.
