Morphology

vena + iliolumbalis

Although 'vena' corresponds to 'vein', the second constituent 'iliolumbalis' is a Latinized anatomical compound not listed in the dictionary and requires knowledge of medical roots (ilio- = ilium/iliac region, lumbal = lumbar). A B1 learner who knows everyday English words would not be able to compose the technical meaning from these parts, so the term is not transparently derivable.

Etymology

Vena iliolumbalis comes from old Latin parts: vena means 'vein', ilio points to the 'hip bone', and lumbalis means the 'lower back'. So the name literally describes a 'vein' near the hip and lower back, which explains why it drains blood from those areas.
