Morphology

sphenoid + fontanelle

This is a compositional compound where 'sphenoid' specifies which 'fontanelle' is meant—the soft spot associated with the sphenoid bone. A learner who knows both constituent meanings can reasonably infer it refers to the soft area of an infant's skull related to the sphenoid bone, so the meaning is transparent.

Etymology

Sphenoid fontanelle is a small, soft area on a baby's skull where the bones fit together like puzzle pieces; sphenoid is the nearby bone and fontanelle means a 'soft spot'. When this area hardens and the bones join, it becomes the adult 'pterion', so the name points to that exact meeting place on the head.
