Morphology

paddle + wheel

The meaning is directly and transparently derived from combining 'paddle' (a broad flat blade) with 'wheel' (a rotating round object): together they describe a wheel fitted with paddles used to move a boat. This noun–noun compound follows a straightforward compositional pattern common across languages and should be understandable to a B1 learner who knows both constituents.

Etymology

Paddle wheel names the real machine on old boats: a wheel with flat boards called paddles around its edge that spins and pushes water. So paddle wheel literally means the wheel that helps 'move a boat'.
