Morphology

vena + ethmoidalis

The term is compositionally built from 'vena' (vein) and 'ethmoidalis' (ethmoidal/related to the ethmoid sinus), so its meaning—a vein associated with the ethmoid sinuses—is directly derivable from the constituents. Although it is a technical Latin-based anatomical label, the morphological pattern (body-part adjective + vein) is regular and cross-linguistically consistent, making it transparent to a learner who knows the parts.

Etymology

Vena ethmoidalis comes from Latin: vena means 'vein' and ethmoidalis means 'from the ethmoid', the thin bone with many small holes behind the nose. So vena ethmoidalis is a vein that carries blood away from the ethmoid sinuses toward the vein near the eye, which is why it means 'one of the veins that drain the ethmoidal sinuses'.
