Morphology

subclavian + vein

The phrase denotes a vein located beneath the clavicle and this meaning is compositionally derived from 'subclavian' (below the clavicle) + 'vein' (blood vessel). This follows standard anatomical naming patterns that are cross-linguistically common, so a learner who knows both constituents can readily infer the MWE meaning.

Etymology

Subclavian vein comes from word parts that mean 'under' and 'collarbone': sub means 'under' and clavian refers to the collarbone, so the name tells you this large vein runs just under the collarbone.
