Morphology

convexo-concave = convex + concave (transparent) = convex + concave

A literal compounding of 'convex' and 'concave' (with a linking vowel), so a learner who knows those adjectives can readily infer the meaning.

Etymology

The word convexo-concave comes from the parts convex ('curved out', like the outside of a ball) and concave ('curved in', like the inside of a bowl). So, a convexo-concave surface 'bulges out' on one side and 'dips in' on the other, with the bulge stronger than the dip.
