Morphology
exostosis = ostosis (semi-transparent) = ex + ost + osis
For someone who knows the medical base word 'ostosis', adding 'ex-' gives the fairly predictable sense of an outward bony growth, but the base itself is highly technical.
Etymology
The word exostosis comes from the Greek parts exo- meaning 'outside' and osteo- meaning 'bone' (as in external and osteoporosis). So an exostosis is a bony growth that sticks out from the surface of a bone.
