Morphology

electret = electric (opaque) = electr + et

The form seems to be built on the electric/electr- element, but the technical meaning 'a material with a permanent electric charge' is not predictable from the parts for an average learner.

Etymology

Electret as an adjective comes from the same idea: from electric and shaped like magnet, meaning 'holding' an electric charge. That's why something described as electret is made of material that keeps a lasting electric charge.
