Morphology
glenoid = glen + oid
The term is a specialized anatomical formation from a combining form 'glen-' (not the common English 'glen' meaning valley) plus the suffix '-oid', so an average learner cannot derive the medical meaning from familiar English parts.
Etymology
Glenoid comes from the Greek root glen- meaning 'socket' and the ending -oid meaning 'like', the same ending you see in humanoid or asteroid. So glenoid means 'socket-like', which is why it describes things related to the shallow shoulder socket.
