Morphology

rotator + cuff

The term is compositional: 'rotator' (a muscle that produces rotation) combined with 'cuff' (a band or covering) yields the sense of a band of rotator muscles/tendons around the shoulder. This matches common anatomical compounding patterns, so a B1 learner who knows the constituent meanings can reasonably infer the MWE meaning.

Etymology

Rotator cuff paints a simple picture: rotator comes from the idea of 'to turn' and cuff is like the edge of a sleeve that wraps around something, so imagine a sleeve of muscle around the shoulder. That's why the term names the muscles and tendons that wrap the shoulder and help the arm turn.
