Etymology: "Nynefold" is formed from "nyne," an Old English numeral meaning nine, and the suffix "-fold," which comes from the Old English "-feald" and means "multiplied by" or "in so many parts." Together they give a plain sense of "nine times over" or "made of nine parts." The base "nyne" is the older form of "nine," and it survived in English alongside the modern spelling for centuries, which is why this compound looks spelled-out in a way "ninefold" does not. The word is a rare, largely archaic formation, so its record is thin. Its meaning follows the pattern of similar compounds such as "twofold" and "threefold," which were regularly used to mean a number of parts or a repetition of a quantity. Most dictionaries record it as an adjective and an adverb, matching how "twofold" and "threefold" function, so a writer could describe something as nynefold or act nynefold in the same breath.
