Morphology

acetaldehyde = aldehyde (semi-transparent) = acet + aldehyde

The name is transparently acet- + aldehyde within chemical nomenclature, but the combining form 'acet-' and the term 'aldehyde' are technical and unfamiliar to average learners.

Etymology

Acetaldehyde is made of acet-, from 'acetic' meaning 'vinegar', and -aldehyde, a word formed from 'alcohol' with the idea of 'hydrogen removed'. So acetaldehyde names a small chemical that comes from the breakdown of alcohol and is closely related to acetic acid 'vinegar', which explains its role in fermented foods and in making acetic acid and perfumes.
