Etymology

The word combines "eighteenth," derived from Old English "eahtatēoþa" (eight + ten + ordinal suffix), and "century," from Latin "centuria" (a group of 100, later a period of 100 years). The hyphenated form emerged in the 18th century itself to describe objects, events, or styles characteristic of that era. The morpheme "cent" preserves its Latin root meaning "hundred," while "ury" evolved as a noun-forming suffix.
