Morphology

backwash = back + wash (transparent) = back + wash

Literal compound 'back' + 'wash' meaning water moving backward; straightforward for learners.

Etymology

Backwash comes from back ('behind') and wash ('move water'). It names the water that moves back behind a boat or wave, so backwash means the backward flow of water left behind something.
