Morphology

sacral + vein

The meaning 'a vein located in the sacral region' is directly and literally derived from combining 'sacral' (pertaining to the sacrum) with 'vein' (a blood vessel). This anatomical noun-noun composition follows regular, compositional patterns common across languages, so a learner who knows both constituents can predict the MWE meaning.

Etymology

The medical name sacral vein combines sacral, meaning the area at the base of the spine, and vein, meaning a 'blood vessel'. It simply names the vein that runs near the lower spine, so that is why doctors use it to refer to that specific blood vessel.
