Etymologies (5)

Toggle American Heritage etymologies American Heritage Dictionary (1)

  1. Middle English, from Old English lifer; see leip- in Indo-European roots.

Toggle Century etymologies Century Dictionary (4)

  1. from live + -er.
  2. from Middle English liver, from Anglo-Saxon lifer = Dutch lever = Middle Low German lever = Old High German libara, lebara, lebera, lepera, Middle High German lebere, German leber = Icelandic lifr = Danish lever = Swedish lefver, liver. Cf. Russian liverŭ, the pluck of animals. Attempts have been made to identify liver, through the assumed earlier stems *lik, *lyēk, with L. jecur = Greek ἠπαρ (ἡπατ-) = Sanskrit yakrit, liver, the medial Tent, labial (v), in this view, having been developed from an orig. guttural (h). A similar change appears in the history of four, five, and prob. eleven and twelve, as well as in wolf.
  3. from Middle English liveren, leveren, from Old French livrer, French livrer = Spanish Portuguese librar = Italian liberare, liverare, livrare = Dutch leveren = German liefern = Danish levere = Swedish levera, deliver, give up, from Latin liberare, set free, liberate, deliver, Middle Latin also (with other forms librare, livrare, after Roman) give up: see liberate and deliver. Hence livery.
  4. apparently from live, or live, + -er; but perhaps, by apheresis, from deliver, adjective
