gearwheel singular

Morphology

gearwheel = gear + wheel (transparent) = gear + wheel

The meaning is directly the combination of 'gear' + 'wheel' (a toothed wheel), which is obvious to learners who know both components.

Etymology

Gearwheel is made from two simple words, gear and wheel. A gear is a toothed part used to 'turn' or 'move' other parts and a wheel is a round object, so a gearwheel is literally a round toothed wheel that fits with other wheels to pass on motion.
