Morphology

cavernous + sinus

The compound is a straightforward adjective+noun composition: 'cavernous' describes having blood-filled cavities and 'sinus' denotes a venous channel, so the phrase literally denotes a venous channel with cavernous spaces. This type of modifier–noun naming pattern is regular and cross-linguistically common, so a B1 learner who knows both constituents can infer the general meaning even if they lack detailed anatomical knowledge.

Etymology

The name cavernous sinus comes from its look: cavernous means 'like a cave' and sinus means 'a hollow or channel'. These are large hollow channels inside the skull that collect and carry blood, so the name explains their job.
