Morphology

rotator = rotate (transparent) = rotate + ator

Used in anatomy to name a structure that produces or enables rotation, which is a direct extension of 'rotate' + '-ator'.

Etymology

Rotator in the body sense also comes from the Latin root rot- meaning 'turn', as in rotate, so a rotator is a part or muscle that makes the arm or another limb turn around a joint.
