Morphology

os + palatinum

The compound is compositionally os (bone) + palatinum (relating to the palate/palatine), so the sense 'bone of the palate' is directly derivable from the parts. However, the form is a Latinized, technical medical term and 'palatinum' is not a common English lexical item at B1, so while the logic is transparent for someone who knows the constituents, the specialized form reduces immediate recognizability for average learners.

Etymology

Os palatinum comes from Latin: os means 'bone' and palatinum means 'palate' or 'roof of the mouth'. So os palatinum literally means 'bone of the palate', which is why it means the two bones at the back of the roof of the mouth that also help form the nose and the eye socket.
