Surface Forms

diphenylamine singular
diphenylamines plural

Morphology

diphenylamine = phenylamine (opaque) = di + phenyl + amine

The formation uses technical chemical combining forms ('di-' + 'phenyl' + 'amine') that are only clear to learners with chemistry knowledge, so the structure is not derivable by an average B1 learner.

Etymology

Diphenylamine breaks into di- ('two'), phenyl (a common chemical 'ring' seen in many chemicals), and amine ('a nitrogen group' like in 'ammonia'), so the name means 'an amine with two phenyl rings' and explains why it is a specific chemical used in lab tests and industry.
