Morphology

interparietal + suture

The term is compositionally built from interparietal (inter- meaning 'between' and parietal referring to the parietal bones) plus suture (an immovable fibrous joint), so the sense 'the joint connecting the two parietal bones of the skull' is directly derivable from the parts. Medical/Latin-derived anatomical formations follow regular morphological patterns, so a learner who knows the constituents can infer the meaning.

Etymology

Interparietal suture is made of three parts: inter- meaning 'between', parietal meaning the bones at the sides and top of the skull, and suture meaning a 'seam' like stitches. So the name paints a simple picture — a seam 'between the parietal bones' — which is why it means the joint that connects those skull bones.
