Etymology

Coined by John Milton in Paradise Lost (1667) as the name for the capital of Hell, blending Greek pan- (all) and daimon (evil spirit). The suffix -ium denotes a place, creating "place of all demons." Over time, it generalized to mean any chaotic or noisy situation, reflecting the imagined tumult of Hell.
