Morphology
ethanoyl + group
The element 'ethanoyl' is a technical chemical morpheme (ethano-/‑yl) that an average B1 learner would not be able to parse from ordinary vocabulary, while 'group' only gives a very general sense of a collection. Understanding the precise structural meaning (CH3CO– / acetyl) requires domain-specific chemistry knowledge rather than simple compositional inference, so the expression is not predictable from its parts for typical learners.
Etymology
Ethanoyl group: The name ethanoyl group comes from ethanoic acid, the main acid in vinegar often called 'acetic acid'. It is the small piece CH3CO– left when that acid loses a hydrogen and sticks to other molecules, so the name helps you remember it is the vinegar-made part that attaches to a molecule and changes how it acts.
