Morphology

glenoid + fossa

The phrase combines 'glenoid' (relating to a socket) and 'fossa' (a bony depression), so a learner who knows both parts can infer it denotes an anatomical hollow associated with a joint socket. However, the term is highly technical and the precise anatomical location and function (e.g. receiving the mandibular condyle in the temporal bone) are specialized and not fully predictable from the constituents, so it is only partially transparent.

Etymology

Glenoid fossa comes from old Greek and Latin words: glenoid means 'socket-like' and fossa means 'shallow hollow'. Picture a small shallow cup on the shoulder blade that holds the top of the arm bone, and that's why the name describes the shoulder socket.
