Morphology

coronoid = corona (semi-transparent) = corono + oid

The suffix -oid clearly signals resemblance, but the corono- element is a learned anatomical form and the specific bone sense is specialized rather than fully predictable.

Etymology

Coronoid comes from an old Greek word corona meaning 'crown'. In some fish and reptiles a separate bone in the lower jaw looks like a small crown, so that bone is called the coronoid.
