Morphology

ramjet = ram + jet (semi-transparent) = ram + jet

The parts 'ram' and 'jet' are visible and compositional, but the specialized technical meaning (air compression by forward motion, no moving parts) is not directly predictable for an average B1 learner.

Etymology

The word ramjet comes from two simple parts: ram ('to push') and jet ('a fast stream of air'). So it literally names an engine that uses its own forward movement to 'push' air into a jet, which is why it has no moving parts and only works at high speed.
