Morphology

hydraulic + motor

The meaning is directly compositional: 'hydraulic' = relating to liquid pressure and 'motor' = a device producing motion, so a learner who knows both constituents can infer it is a motor powered by hydraulic pressure. Although technical, the structure follows regular noun‑noun composition and similar terms exist across languages, making the sense predictable to a B1 learner familiar with the component words.

Etymology

Hydraulic motor comes from the simple picture of a motor turned by hydraulic liquid: when oil or water is pushed into the machine, the moving liquid makes parts inside spin like a small wheel. So, the name means a machine that uses the push of liquid to 'turn' and 'move' things.
