Morphology

involute = volute (semi-transparent) = in + volute

Formally 'in-' (inward) + 'volute' (spiral) yields the literal meaning 'rolled inward', but 'volute' is a rare base and may be unfamiliar to many learners.

Etymology

The word involute comes from Latin parts in- 'in' and volvere 'to roll'. Think of a petal or leaf 'rolled inward' inside a bud, which is why botanists call leaves that curl in involute.
