Morphology
sphenoid = spheno + oid
The element 'spheno-' is a Greek combining form ('wedge') not a standalone English word and the term is specialized anatomical vocabulary, so learners cannot reliably derive the meaning from its parts.
Etymology
The word sphenoid comes from Greek parts sphen 'wedge' and -oid 'like' or 'shape', so it means 'wedge-shaped'. That's why the sphenoid bone is a wedge-shaped, butterfly-like bone at the base of the skull that helps form the eye socket and holds the pituitary gland.
