Morphology

2-methylpropenoic + acid

This is a technical systematic chemical name (methacrylic acid) that requires specialist knowledge of organic nomenclature to interpret; a B1 learner who only knows the common word 'acid' (and not the morphemes like '2‑methyl' or 'propenoic') will not be able to derive the meaning. The first constituent is not a normal lexical item in general English and the overall referent and properties are not predictable from everyday vocabulary, so it is not transparent to learners.

Etymology

2-Methylpropenoic acid describes the molecule's shape: propenoic means a 'three-carbon chain' with a double bond and 2-methyl shows a small 'methyl' branch on the second carbon, while acid tells you it behaves like an acid. That's why this small, double-bonded acid is used 'to make resins and plastics'.
