Morphology

glycol = glyco + ol

Formed from the specialized combining form 'glyco-' and the chemical suffix '-ol', which are technical morphemes unfamiliar to average B1 learners, so the meaning is not derivable from common English vocabulary.

Etymology

The word glycol comes from the Greek root glyk- meaning 'sweet' and the chemical ending -ol meaning 'alcohol', like the root in glucose, which is a sugar, and the ending in ethanol. So a glycol is literally a 'sweet alcohol', a kind of alcohol used as antifreeze or a solvent, which explains its modern meaning.
