Definition of giddy

The word "giddy" has an interesting origin. It comes from the Old English words "gidda" or "giddian," which mean "dizzy" or "light-headed." This sense of dizziness is thought to have come from the idea that the blood was rushing to the head, causing a feeling of intoxication or euphoria. In Middle English (circa 1300), "giddy" took on a new meaning, referring to a person who was reckless, flighty, or foolish. This sense of the word is still used today, describing someone who acts impulsively or with a lack of seriousness. The connection between the original sense of giddy and the modern sense is thought to be that someone who is feeling dizzy or light-headed might also act in a reckless or careless manner. Over time, the word "giddy" has developed a range of connotations, including excitement, nervousness, and even playfulness.
