Morphology

acetylation = acetylate (opaque) = acetyl + ation

The derivation from 'acetylate' to 'acetylation' is regular, but the biochemical meaning is specialized and not readily recoverable for most learners.

Etymology

Acetylation comes from acetyl, which traces back to Latin acetum meaning 'vinegar', and the ending -ation meaning 'the action of'. So, acetylation is the action of adding an 'acetyl' (a small part related to 'acetic acid', the acid in 'vinegar') to a molecule, which helps explain why this change can change a protein's or enzyme's function.
