Morphology

occipitomastoid + suture

The phrase denotes a specific anatomical joint using technical morphemes (occipito-, mastoid) that are not part of general B1 vocabulary; knowing only the common word 'suture' would not let a learner identify which bones are joined. Because the crucial constituent is specialized and domain-specific rather than a transparent everyday combination, the meaning is not derivable for an average B1 learner.

Etymology

Occipitomastoid suture names the seam where the bone at the back of the head (occipito) meets the bone behind the ear (mastoid). So, the term refers to 'the joint between these two bones'.
