Morphology

frontal + suture

The meaning is directly compositional: 'frontal' (relating to the front/forehead) + 'suture' (a cranial joint) yields the suture located at the frontal bone, so a learner who knows both constituents can infer its meaning. This follows a regular adjective+noun anatomical naming pattern common across languages, making it immediately understandable rather than idiomatic.

Etymology

Frontal suture names the 'seam' between the two halves of the forehead bone. frontal means forehead and suture is like a stitched 'seam' that joins two pieces, so the phrase refers to the visible line where the skull's frontal bone meets and usually closes by age six.
