Surface Forms

Morphology

phenylenediamine = phenylene + diamine (semi-transparent) = phenylene + diamine

The word is transparently built from chemical combining forms ('phenylene' + 'diamine'), but these are technical morphemes that an average B1 learner without chemistry knowledge will not readily interpret.

Etymology

Phenylenediamine is a chemical name made of three parts: phenyl, a ring shape found in many molecules, di-, which means 'two', and amine, a group with nitrogen, like the amino in amino acids. So, phenylenediamine is a molecule with two amine groups on a phenyl ring, which helps explain why it is used in dyes and hair color.
