Etymology

The word "mindless" combines "mind," derived from Old English gemynd (memory, thought), with the suffix "-less," from Old English -lēas (without). The fusion reflects a straightforward negation: "without a mind" or "lacking thought." Over time, it evolved to describe both unintelligent behavior and repetitive tasks devoid of mental engagement.
