Morphology

nonporous = porous (transparent) = non + porous

Meaning is directly derived from the adjective 'porous' with the negative prefix 'non-', i.e., 'not porous'.

Etymology

Nonporous comes from non- meaning 'not' and porous from pore meaning 'small hole', like the holes in a sponge. So something nonporous has no small holes and does not let water or air pass through.
