Morphology

polyethylene = ethylene (semi-transparent) = poly + ethylene

The word is transparently built from the combining form poly- plus ethylene, but the specialized chemical meaning is not fully obvious to an average learner.

Etymology

Polyethylene starts with poly- meaning 'many', like in polygon, and ends with ethylene, the name for the small chemical 'part' used in plastics. So polyethylene means 'many ethylene parts', which helps you remember it is a plastic made of long chains of the same parts, giving it lightness, flexibility, and strength.
