Morphology

carinate = carina (semi-transparent) = carina + ate

Formally built from 'carina' + '-ate' yielding 'keel-shaped', but both the root and the resulting adjective are technical and likely unfamiliar to B1 learners.

Etymology

Carinate comes from the Latin carina, meaning 'keel', the long ridge under a boat. So a carinate leaf, bone, or shell has a raised ridge like a boat's keel, which helps explain the word's modern use.
