Morphology

ethmoid + sinus

The compound is fully compositional: 'ethmoid' names the ethmoid bone/region and 'sinus' denotes an air-filled cavity, so 'ethmoid sinus' straightforwardly means the sinus associated with the ethmoid area. This follows a common anatomical noun+noun naming pattern (type/location + organ), which a learner who knows both constituents can derive cross-linguistically.

Etymology

Ethmoid sinus comes from two old words: ethmoid from Greek meaning 'sieve' and sinus meaning 'small space' or 'cavity', so the name paints a picture of a sieve-like bone with many tiny air pockets between the nose and the eyes. That's why ethmoid sinus means 'one of the small air-filled cavities behind the bridge of the nose'.
