Word History

Etymology

Middle English arterie, borrowed from Anglo-French & Latin; Anglo-French arteire, arterie, borrowed from Latin artēria "trachea, bronchial tubes (in plural artēriae), artery," borrowed from Greek artēría, from ar- (contracted from *awer-), base of aeírein "to join, attach, harness" (of uncertain origin) + -tēr, agentive suffix + -ia -ia entry 1 — more at aorta

Note: Compare, without the second suffix, Greek artḗr "something by which a burden is carried" (Septuagint). The semantic relation between the verb aeírein and the sense "trachea" parallels that between the verb and the derivative aortḗ "aorta, bronchial tubes" (see aorta). The extension of the meaning from "trachea" to "artery" is presumably because the arteries were believed to carry air to the extremities of the body as well as blood.
