Morphology

porous = pore (transparent) = pore + ous

The adjective is a regular formation from the noun 'pore' with the productive suffix '-ous', so its meaning is directly predictable from 'pore'.

Etymology

Porous comes from an old Greek word poros meaning 'passage' or 'pore', the same root you see in the English word pore. So something porous is full of tiny holes or spaces that let air, water, or other things pass through.
