Morphology

os + frontale

The phrase is compositionally built from 'os' (bone) + 'frontale' (frontal), so its meaning — the frontal bone of the skull — is directly derivable from the constituents. Although 'frontale' is a Latin/technical form and may be unfamiliar to typical B1 learners, if a learner knows both elements the semantic composition is transparent.

Etymology

Os frontale comes from Latin words: os meaning 'bone' and frontale meaning 'forehead' or 'front of the head'. It names the large bone at the front of the skull that makes the forehead and the top of the eye sockets, so the name directly shows its place and job.
