Note: The word appears earlier as Middle English aborchi, abhorti, adorte "aorta," comparable with Middle French aborthi and Medieval Latin adorti; these forms most likely reflect Latin translation of the Arabic versions of Greek medical texts. — The Greek medical term aortḗ belongs to a small set of forms based on aeírein that refer to both attachment and suspension, as áōrto "was hung" ("[máchaira]… pàr xípheos méga kouleón aeìn áōrto" - "[the knife]… was always hung beside the great sheath of his sword"—Iliad 3, 272), aortḗr "belt or strap for hanging a sword or satchel," and aórtēs "knapsack." Perhaps the aorta was pictured as an organ attached to and suspended from the heart in the way a scabbard is hung from a belt. Note that the verb aeírein displays two sets of meanings, that of harnessing and attachment (outside of nominal derivation almost always with the prefix syn- syn-) and of lifting or raising. Whether or not these should be regarded as two verbs of distinct origin or as semantic branches of the same verb is unclear. Though an Indo-European verb base *h₂u̯er- can be reconstructed from the Greek evidence, there appear to be no definitely comparable forms outside Greek. See also artery, meteor.
