Morphology

conspiracy + theory

The meaning is compositionally built from 'conspiracy' (a secretive plot) + 'theory' (an explanatory belief) — essentially 'a theory about a conspiracy' — so a B1 learner who knows both constituents can infer the basic sense. The N+N compound pattern is cross-linguistically common; only pragmatic nuances (e.g. often implying unsupported belief) go beyond simple compositional meaning but do not block transparency.

Etymology

The noun conspiracy theory comes from conspiracy (a secret plan by a group) and theory (an idea that explains something). Imagine a small group meeting in secret and someone offering the idea that they control events; that's why the phrase means believing events are secretly controlled by a group, often 'without proof'.
