   Similarobscure, arcane, abstruse, recondite, cryptic

   Oppositeaccessible, popular, mainstream

   Note

   The word began with an inner circle: Greek esōterikós meant "belonging to an inner circle," and esoteric first named the secret teachings of Greek philosophers, as against their public, or exoteric, ones. Now it covers knowledge that is merely specialized as well, such as an engineering manual few can follow. Source
