prop wash singular

Morphology

prop + wash

The meaning is compositionally derived from 'prop' (propeller blade assembly) + 'wash' (turbulent airflow), so 'prop wash' straightforwardly denotes the disturbed airflow produced by a propeller. This follows a common, cross-linguistic compound pattern (similar to 'jet wash' or 'wake') and would be understandable to a B1 learner who knows both constituent senses.

Etymology

Prop wash comes from the simple image of a spinning propeller pushing air backward: the rotating prop blades create a strong moving wash of air that can blow or shake things nearby. So, prop wash means the strong, disturbed air behind a propeller.
