means The act of making something new again — restoring, refreshing, or extending it, whether a subscription, a contract, a vow, or a sense of vitality.

from From the verb "renew," itself built from the prefix "re-" ("again") plus "new" — from Old English "nīwe," a cousin of Latin "novus" and Greek "neos," all tracing back to the same ancient root for newness. The "-al" suffix turns the action into a thing, the way "arrive" becomes "arrival." So at heart the word simply means "a new-ing again" — making fresh what time had worn down.
