Morphology

planoconcave = concave (semi-transparent) = plano + concave

Meaning composes 'plano-' (flat) with 'concave' (curved inward), but 'plano' is a bound combining form rather than a common standalone word, so learners may need prior exposure.

Etymology

The word planoconcave combines plano- meaning 'flat', like a plane surface, and concave meaning 'hollow', like a cave, so it describes a lens that is flat on one side and hollow on the other.
