giddy

Giddy is an adjective with two primary senses. In a physical or medical sense, giddy describes a sensation of lightheadedness or vertigo, often accompanied by unsteadiness or dizziness. In a figurative sense, it describes a mood characterized by frivolous, flighty, or overly carefree excitement, sometimes bordering on silliness. The noun form giddiness denotes the sensation of dizziness or an elevated mood.

The word dates from the Middle English period, with early senses relating to foolish or silly behavior and, consequently, to a lack of steadiness. The sense relating to dizziness emerged later, evolving from the idea of a light-headed mental state. Etymology is uncertain; it is related to words in other Germanic languages that express lightness or brightness of mind, and it shares roots with terms describing mental flimsiness.

Usage notes: When describing a physical sensation, giddy is often used with verbs like feel, become, or after a spin. In figurative use, it typically modifies mood or behavior, as in giddy with joy or laughter, or as a more negative remark about someone being giddy and irresponsible. It can carry a mild pejorative connotation if used to imply frivolousness.

Examples: She felt giddy after riding the roller coaster. The crowd grew giddy with excitement as the performers took the stage. In literature, giddy moments can be used to convey a carefree, impulsive atmosphere or a sudden loss of balance in a character’s perception.
