The word "megalomania" combines two Greek-derived morphemes: "megalo-" (from Greek megas, meaning "great" or "large") and "-mania" (from Greek mania, meaning "madness" or "frenzy"). Historically, it emerged in the 19th century to describe a psychiatric delusion of exaggerated self-importance, reflecting the literal sense of "madness for greatness." The term retains its clinical and colloquial usage, often critiquing unchecked ambition or narcissism.
