Linguistic Origin & Historical Etymology

Derived from the Old English word 'gemædde', meaning 'out of one's mind' or 'foolish', which stems from Proto-Germanic '*gamadjaną'. Over centuries, the meaning shifted from a state of severe mental illness or impairment to include intense anger, extreme folly, and enthusiastic excitement.
