Lunatic
Meaning
A person who is considered to be mentally ill, extremely foolish, or behaving in a wild and unpredictable way.
Origin
The word "lunatic" directly descends from the Latin "lunaticus," which itself comes from "luna," meaning "moon." For centuries, a powerful and widespread belief held that the moon's phases had a profound influence on human behavior, particularly on mental stability. Full moons were especially implicated in causing fits of madness, epilepsy, and other erratic conditions, leading to the idea that those afflicted were "moonstruck." This ancient superstition, woven deeply into folklore and early medical thought, firmly established the term's meaning, forever binding mental instability to the celestial movements of our closest satellite.
