Morphology

parietomastoid + suture

The term names an anatomical joint formed by combining the location element (parieto‑/mastoid, i.e. parietal + mastoid parts of the skull) with 'suture' (an immovable cranial joint), so the meaning is directly compositional: the suture between the parietal and mastoid regions. This kind of anatomical compound is predictable and follows transparent naming patterns found across languages, so a learner who knows the constituent parts would be able to derive the meaning.

Etymology

Parietomastoid suture names the seam, a suture, where two skull parts meet: the parietal bone at the top-side of the head and the mastoid part just behind the ear. So, the term means the 'join' or 'seam' between those two bones.
