Morphology

corpuscular + theory

The phrase is transparently compositional: 'corpuscular' means relating to small particles and 'theory' means an explanatory framework, so a B1 learner who knows both words can infer it denotes a theory about particles (in historical physics, specifically about light). The lexical items are morphologically and semantically regular and have cross‑linguistic cognates, making the overall meaning directly derivable from the parts.

Etymology

Corpuscular theory comes from corpuscular, a word meaning 'little body', and theory, meaning an idea or explanation. It pictures light as a stream of tiny 'particles', so it now means a 'theory that light is made of particles' rather than a 'wave'.
