Morphology

mydriasis = mydri + asis

The term is a specialized medical formation (combining form + pathological suffix) that an average B1 learner cannot reliably interpret from familiar English vocabulary.

Etymology

The word mydriasis comes from a Greek root mydri- that means 'open wide', so it names the state when the pupil of the eye becomes very large. It is like the common word dilate because the pupil opens to let in more light.
