Morphology
ethanedioic + acid
The constituent 'ethanedioic' is a technical systematic chemical term (oxalic acid) that a B1 learner would not be able to parse from general vocabulary; even knowing 'acid', the specialized morphology (ethane + dioic) and the specific properties (toxic, crystalline, uses) are not inferable from ordinary word knowledge. Because this is domain-specific nomenclature rather than a transparent compositional phrase, the overall meaning cannot be derived by an average B1 learner.
Etymology
Ethanedioic acid gets its name from simple parts used by chemists: ethane means 'two carbon atoms' and dioic acid means 'two acid groups'. So the name literally says a two-carbon acid with two acidic parts, and it is the formal name for common oxalic acid, a plant acid that can be 'toxic'.
