Morphology

carrier + wave

The compound is directly compositional: 'carrier' (one that carries) + 'wave' (a wave) yields a 'wave that carries' information, so the technical meaning is a straightforward extension of the parts. This follows a standard noun‑noun compounding pattern found across languages, so a B1 learner who knows both constituents can reasonably infer the MWE's meaning despite its technical register.

Etymology

Carrier wave comes from the picture of a carrier (like a small boat) on a wave: imagine the wave carrying a boat that holds a message. So a carrier wave is a radio wave that 'carries' information by small changes, and a radio reads those changes as sound or data.
