Morphology

dextrorotary = rotary (semi-transparent) = dextro + rotary

The composition 'dextro-' (right) + 'rotary' yields 'right-turning', but 'dextro-' is a technical combining form unfamiliar to average learners.

Etymology

The word dextrorotary comes from the Latin root dexter meaning 'right' and the root rotate meaning 'turn', as in ambidextrous. So a dextrorotary substance 'turns' light to the 'right', or clockwise.
