Etymology: The superlative "abstrusest" is built on "abstruse," which was borrowed directly from Latin "abstrusus," meaning "concealed" or "hidden." That Latin adjective came from the verb "abstrudere," literally "to thrust away," combining "abs-" ("away from") with "trudere" ("to push or shove"). So the word's core idea is something pushed out of sight, placed beyond easy reach of the eye or mind. The sense has stayed close to that picture. Something abstruse is buried deep enough that ordinary understanding has to dig to find it, which is why the word now describes difficult subjects, obscure arguments, and dense technical writing. The same root sits behind a family of related words across European languages, including Italian "astruso," Spanish "abstruso," and German "abstrus," all carrying the notion of hidden depth.
