Morphology
The meaning is directly composed from 'cotyloid' (cup-shaped joint cavity) and 'joint' (a point where bones articulate), so a learner who knows both constituents can infer a joint with a cup-like socket. This is a transparent, straightforward anatomical composition and corresponds to a common cross-linguistic concept (ball-and-socket type), making it comprehensible to a B1 learner.
Etymology
Cotyloid joint pictures a 'cup-and-ball' fit: the round head of one bone sits inside a cup-like socket. The word cotyloid may come from an old Greek word for 'cup', so the name helps you remember that this joint lets a bone move in many directions.
