Etymology

The word "craziness" derives from "crazy," which originated in the 16th century from the verb "craze" (to shatter or break), itself from Old Norse "krasa" (to shatter). The suffix "-ness" (from Old English "-nes") transforms adjectives into nouns denoting a state or condition. Thus, "craziness" literally means "the state of being crazy," reflecting either mental instability or intense excitement.
