Morphology

rotary = rotate (transparent) = rotate + ary

The adjective is a straightforward derivation from the verb 'rotate' with the productive suffix '-ary' meaning 'relating to rotation'.

Etymology

Rotary comes from the Latin root rota 'wheel' and is the same root as rotate, so picture a wheel turning — that is why rotary describes something that moves in a circle or around an axis.
