Morphology

choroidal = choroid (semi-transparent) = choroid + al

The adjective is transparently formed from the anatomical noun 'choroid' plus the common suffix '-al', but the base word is a specialized technical term.

Etymology

The word choroidal comes from the Greek root chorion, which means 'membrane'. The choroid is the thin layer of blood vessels under the retina in the eye, so choroidal means 'relating to that layer'.
