Morphology

supraorbital + torus

The element 'supraorbital' clearly signals location above the eye socket, so the locative component is transparent. However, 'torus' is a technical term whose everyday/geometric sense (a rotated circle) does not transparently map to 'a bony ridge' without anatomical knowledge, so the overall meaning is only partially predictable to a B1 learner.

Etymology

Supraorbital torus is a name that literally shows a bony 'ridge' 'above' the 'eye sockets'. The parts supra ('above'), orbital ('eye socket') and torus ('ridge') give the image of a thick brow shelf, so the term refers to the strong ridge seen on some early human skulls and in a few people today.
