Morphology

acetic + anhydride

The compound name is fully compositional: 'acetic' signals it is derived from acetic acid and 'anhydride' denotes a dehydration-derived chemical, so the basic identity of the substance is directly inferable from the parts. This follows standard chemical naming conventions (common across many languages), so a B1 learner who knows the constituent meanings would grasp the general meaning even if they lack technical details about uses.

Etymology

Acetic anhydride comes from two words: acetic, linked to 'vinegar' because acetic acid smells like vinegar, and anhydride, which means 'without water' because the compound forms when water is removed from acid molecules. So the name tells you it is a chemical made from acetic acid by removing water and explains why it is used in labs to add parts of that acid to other substances.
