Morphology

carbonyl = carbon (semi-transparent) = carbon + yl

Formally built from 'carbon' + the chemical combining form '-yl', but the specialized meaning 'the C=O functional group' is technical and not obvious to general learners.

Etymology

Carbonyl comes from carbon, from the Latin carbo which means 'coal', and the ending -yl meaning a 'part' or 'group'. So a carbonyl group is literally a carbon 'part' of a molecule, and in chemistry this name is used for the carbon atom joined to an oxygen atom.
