Morphology

ammonium + carbamate

The noun names a chemical compound made from ammonium and carbamate, so its meaning is directly compositional: an ammonium–carbamate salt. Although the term is technical, it follows regular chemical naming patterns that are cross-linguistically regular, so a learner who knows both constituents can infer the compound meaning.

Etymology

The chemical ammonium carbamate is named for its parts: the ammonium part comes from ammonia (a source of nitrogen) and the carbamate part is a carbon-based partner. Together they form a white salt used to give nitrogen to soil, so the name fits its use as a 'fertilizer'.
