Morphology

common + cardinal + vein

The phrase is compositionally built from 'common' (shared), 'cardinal' (primary/main) and 'vein' (blood vessel), so a learner who knows the constituents can infer it denotes a main/shared vein. However, this is a technical embryological term and 'cardinal' as an anatomical label may be unfamiliar, so the precise embryonic/junctional sense is not fully predictable to a B1 learner.

Etymology

Common cardinal vein comes from simple parts: cardinal once meant 'main', common means 'shared', and vein is a blood vessel. Think of small streams joining a larger river that flows to the heart in the early embryo; that's why the name means the main shared vein that returns blood to the heart.
