Surface Forms

Morphology

trichloroethylene = ethylene (opaque) = trichloro + ethylene

The formation follows specialized chemical nomenclature (addition of chlorine atoms to an ethylene base) and is not guessable by an average B1 learner.

Etymology

Trichloroethylene is made of three parts: tri- meaning 'three', chloro- from 'chlorine', and ethylene, a name for a simple two-carbon chemical. So the name tells you it is an ethylene with three chlorine atoms attached, which is why it acts as a strong solvent and is very toxic.
