Etymology: The root of this word is Latin "durus," meaning "hard," and the Latin verb "durare," "to last," grew from it. Latin speakers built "perdurare" by adding "per-," meaning "through" or "thoroughly," so the sense was lasting right through to the end. English took the idea from Old French "perdurable," and the noun form ends in the suffix "-ness," which turns an adjective into a noun meaning "the quality of." Its close relative is the common word "durable," which came into English through the same Latin family. Where "durable" is an ordinary adjective, this noun names the abstract quality of going on forever, and it appears in Middle English writing.
