Etymology

The word "madness" originates from the Old English gemǣdde (past participle of gemǣdan, "to make mad"), derived from gemād ("foolish, insane"). The root "mad" traces back to Proto-Germanic *ga-maidaz ("changed, altered," implying a departure from sanity). The suffix "-ness" (Old English -nes) transforms adjectives into nouns denoting a state or condition. Thus, "madness" literally means "the state of being mad," evolving from early connotations of mental alteration to modern meanings of insanity or extreme folly.
