Morphology

dextrorotatory = rotatory (semi-transparent) = dextro + rotate + ory

The base rotatory is directly interpretable as something that rotates, and dextro- straightforwardly adds the sense of rightward direction.

Etymology

Dextrorotatory comes from dextro- meaning 'right' and the same root as rotate, meaning 'turn'. So a dextrorotatory substance 'turns' the plane of polarized light to the right, or clockwise, when you look along the direction of the light.
