Morphology

opacity = opaque (transparent) = opaque + ity

Standard noun formation from the adjective 'opaque' indicating the state or quality of being not transparent; learners who know 'opaque' can infer this meaning.

Etymology

Opacity comes from the Latin opacus, meaning 'dark' or 'shaded', and shares the same root as opaque. So, think of a window that blocks light — its opacity is how much it stops light from passing through.
