Morphology

amaurosis = amauro + osis

The root 'amauro-' is a Greek medical combining form (not a standalone English word) and the suffix '-osis' produces a specialized clinical term, so an average B1 learner cannot derive the meaning from the parts.

Etymology

The word amaurosis comes from the Greek amauros, which means 'dim' or 'dark'. That's why amaurosis describes a loss or 'darkening' of vision, like a curtain or shadow hiding what you see.
