Morphology

oxalacetic + acid

Although the headword contains the transparent noun 'acid', the modifier 'oxalacetic' is a specialized biochemical term that a B1 learner who only knows ordinary constituent meanings would not be able to parse or derive the specific metabolic meaning. The compound follows a scientific naming pattern, but its internal morphology and referent are technical and unpredictable for general learners, so the overall meaning is not recoverable from the parts.

Etymology

Oxalacetic acid comes from joining two older acid names: oxalic (from a sour plant called oxalis) and acetic (from 'vinegar'). This name shows the chemical is related to both oxalic and acetic acids, so its name tells scientists about its structure and its role in the body's energy processes.
