Morphology

motor + horn

The meaning is directly compositional: 'motor' (a device producing motion) + 'horn' (a warning device) clearly denotes a horn fitted to a motor/vehicle. This straightforward noun–noun compound follows common cross-linguistic patterns, so a B1 learner who knows both words will readily infer the MWE meaning.

Etymology

Motor horn comes from early motor vehicles where the horn was a real animal horn or a rubber bulb people squeezed to make a loud 'honk'. That's why motor horn means the device on a vehicle that makes a loud sound to 'warn' or 'alert' others.
