Morphology

layer = lay (transparent) = lay + er

The word is built from 'lay' + '-er', with the sense of something laid down being fairly direct.

Etymology

Layer comes from the simple verb lay, which means 'to put down'. A layer is something that has been laid down — like a sheet of paint, a cake tier, or a cover on the skin — so this image explains the word's physical meaning.
