Morphology

overlayer = layer (transparent) = over + layer

The meaning is directly derived from 'over' + 'layer' — a layer placed over something — which is clear to learners familiar with the components.

Etymology

Overlayer comes from the parts over, which means 'on top', and layer, which means 'a flat sheet or level'. So, an overlayer is a layer put on top of a building's structure to act as a protective cover and a base for the final surface.
