abstruse

/æbˈstruːs/
IELTSAcademic
adjective

Difficult to understand; known only to a few because it is complex or specialized.

  • The professor's **abstruse** lecture confused most students.
  • It is **abstruse** philosophy.
  • They published an **abstruse** paper.

Adinary Nuance

Near-neighbors: Unlike difficult (general challenge) or complex (organized intricacy), abstruse suggests specialized knowledge that intentionally eludes most people. It often implies the obscurity is unnecessary or pretentious. Choose abstruse when you want to stress exclusivity of understanding rather than plain hard work.
