Morphology

radiopaque = opaque (semi-transparent) = radio + opaque

Meaning is directly built as 'radio(radiation) + opaque', but the combining form 'radio-' is technical and may be unfamiliar or confusable with the noun 'radio' for many learners.

Etymology

The word radiopaque comes from radi- meaning 'ray', the same root in radio and radiant, and opaque meaning 'not see-through'. So a radiopaque object does not let X-rays pass and appears white on an X-ray.
