Morphology
auxin = aux + in
Formed from the combining form 'aux-' (not a standalone English word) plus the chemical noun suffix '-in'; the components are technical/etymological and not accessible to an average B1 learner.
Etymology
The word auxin comes from the Greek auxein, which means 'to grow'. So auxin is the plant chemical that makes cells grow longer and helps roots and buds form.
