1520s, "render as good as new (materially), restore to a good condition," a back-formation from renovation or else from Latin renovatus, past participle of renovare "renew, restore." Related: Renovated; renovating.
Earlier verbs were renovelen "renew, repair, rebuild" (early 14c., from Old French renoveler); renoven "become renewed; renew," early 15c., from Old French renover from Latin renovare). Later, renovize was tried as a contraction of renovate and modernize (1933).
