Etymology

The word "useless" combines the root "use" (from Old French user, meaning "to employ or utilize") with the suffix "-less" (from Old English -lēas, meaning "without"). The fusion creates a straightforward negation—literally "without use." This construction reflects a common pattern in English where "-less" transforms a noun or verb into an adjective denoting absence. Over time, "useless" expanded from its literal sense ("not functional") to include figurative meanings like "incompetent."
