Morphology

arteria + lumbalis

Although the item is a Latin anatomical label, its meaning is compositionally transparent: 'arteria' corresponds to 'artery' and 'lumbalis' to 'lumbar'/'of the lower back', so the phrase literally denotes an artery supplying the lumbar region. This morphological composition is regular and mirrors equivalents in other languages (e.g., Spanish 'arteria lumbar'), making the sense predictable for a learner who knows the constituent roots.

Etymology

Arteria lumbalis comes from old Latin words, with arteria meaning 'artery', a blood vessel, and lumbalis meaning 'lower back'. So the name paints the image of a blood vessel that goes to the lower back, which is why it means the artery that supplies that area.
