Etymology

The word "ceaseless" combines "cease," derived from Old French cesser (to stop) and Latin cessare (to delay or halt), with the suffix "-less," from Old English -lēas (meaning "without"). The fusion creates a vivid negation—literally "without stopping." Over time, it evolved to emphasize perpetual continuity, often describing actions or states that endure indefinitely.
