Morphology

acetic + acid

The meaning is directly derivable from the constituents: 'acetic' (= relating to vinegar) + 'acid' yields a vinegar-related acid, so the compound is compositional and predictable. This ADJ+NOUN chemical naming pattern is cross-linguistically common (e.g., Spanish/French equivalents), so a learner who knows both words can infer the MWE's meaning.

Etymology

The name acetic acid comes from an old word for 'vinegar'. This acid is the part that makes 'vinegar' taste sour, so the name helps you remember that it is the chemical found in vinegar.
