Etymology

The word "unanswered" combines the negative prefix "un-" (from Old English "un-," meaning "not") with the root "answer" (from Old English "andswaru," meaning "a reply") and the suffix "-ed" (indicating a past participle). The logical progression reflects something that has "not been replied to" or "not received a response." Over time, it also gained the figurative sense of being ignored or left unresolved.
