acetal singular

Morphology

acetal = acetic + alcohol (opaque) = acet + al

Although historically coined as a blend of 'acetic' and 'alcohol', that relationship does not help an average learner infer the modern chemical meaning.

Etymology

Acetal comes from the same root acet- as acetic and acid, from an old word meaning 'vinegar'. Chemists used that root for compounds related to acetic acid, so acetal now names the kind of chemical made when a certain 'aldehyde' reacts with alcohols.
