Origin of lung

  • Middle English lunge from Old English lungen lungs legwh- in Indo-European roots

    From American Heritage Dictionary of the English Language, 5th Edition

  • From Middle English, from Old English lungen, from Proto-Germanic *lungw- (“the light organ"), from Proto-Indo-European *lengÊ·Ê°- (“not heavy, agile, nimble"); cf. *h₁lengÊ·Ê°-, whence ultimately also light. Cognate with West Frisian long, Dutch long, German Lunge, Danish lunge, Swedish lunga, Icelandic lunga, and also Russian лёгкое (lÑ‘gkoe) (lung), Ancient Greek ἐλαφρός (ἐlafrós) and perhaps Albanian lungë (“blister, bulge"). Compare Latin levis and Old English lÄ“oht (Modern English light). See also lights ("lungs").
