Etymology: "Ineffaceably" is simply the adverb of "ineffaceable," meaning "not able to be effaced or erased." It is built by attaching the adverbial suffix "-ly" to that adjective, so the word describes an action done in a way that cannot be rubbed out or undone. The adjective itself is formed from the verb "efface," which comes from French "effacer," meaning "to rub out" or "to wipe out," and ultimately from Latin "ex-" ("out") and "facies" ("face" or "surface"). Adding the prefix "in-" ("not") and the suffix "-able" ("capable of") gives the sense of something that cannot be wiped from a surface.
