Morphology

gear + wheel

The meaning 'a wheel with teeth designed to mesh with another toothed component' is directly and compositionally derived from 'gear' (a toothed mechanism) + 'wheel' (a rotating circular object). This noun–noun compounding is a straightforward, cross-linguistically common pattern, so a B1 learner who knows both constituents will readily infer the MWE's meaning.

Etymology

Gear wheel is a wheel with 'teeth' at the edge called a gear, and these 'teeth' fit into another wheel so when one turns the other turns too. That's why the name means a part that makes another wheel turn and can change speed or direction.
