Morphology
auxetic = auxesis (opaque) = aux + etic
Formed from the specialized combining form 'aux-' plus the adjectival suffix '-etic'; the root is not a productive or familiar standalone English word, so learners cannot deduce the meaning from components.
Etymology
Auxetic comes from the Greek root auxein, meaning 'to increase' or 'grow'. So an auxetic material gets wider or increases in size when you stretch it, not thinner.
