Etymology

The word "unusual" combines the prefix "un-" (Old English "un-," meaning "not") with "usual" (from Latin "usualis," derived from "usus," meaning "use" or "custom"). The prefix negates the root, creating a meaning of "not customary" or "out of the ordinary." Over time, it evolved to emphasize rarity or distinctiveness.
