Etymology: < classical Latin abstrūsus concealed, hidden, secret, recondite, use as adjective of past participle of abstrūdere abstrude v. Compare Middle French, French abstruse (1531), Catalan abstrús (1696), Spanish abstruso (1726), Italian astruso (1623).In his 1656 commentary on H. L'Estrange's Reign King Charles (1655), P.
