Morphology

tetrachloroethylene = chloroethylene (semi-transparent) = tetra + chloro + ethylene

Formed by adding the numeric prefix 'tetra-' to 'chloroethylene'; the morphological formation is regular, but interpreting it requires chemistry knowledge beyond an average B1 learner.

Etymology

Tetrachloroethylene breaks into tetra- 'four', chloro- 'chlorine', the same 'chlorine' you know from pools, and ethylene, a very small molecule made of two carbon atoms. So the name says it is ethylene with four chlorine atoms attached, which helps explain why it is a strong solvent used for cleaning.
