Morphology

vena + vertebralis + accessoria

The term is fully compositional: vena = vein, vertebralis = vertebral (related to the vertebra), and accessoria = accessory, so the phrase literally reads 'accessory vertebral vein' and the anatomical role is directly derived from these parts. Although vertebralis and accessoria are technical/Latin forms not listed here, their meanings map transparently to common English morphemes, so a learner who knows the constituent meanings would infer the MWE's meaning.

Etymology

Vena vertebralis accessoria comes from Latin words: vena meaning 'vein', vertebralis meaning 'of the spine', and accessoria meaning 'extra'. The name paints a simple picture of an 'extra' small vein running next to the main vein along the spine in the neck, so it refers to an additional vein that helps drain blood from that area.
