Morphology
cyclohexylamine = cyclohexyl (opaque) = cyclohexyl + amine
The form is systematic chemical nomenclature ('cyclohexyl' + '-amine'), but the term denotes a specialized organic compound and its meaning is not derivable by an average B1 learner.
Etymology
Cyclohexylamine is made of simple parts you can remember: cyclo- means 'circle', hexyl means 'six', and amine comes from 'ammonia'. So the name describes a chemical with a six‑carbon ring attached to an ammonia-like group, which fits its modern use as a colorless liquid in industry.
