Where it comes from
From Middle English lunge, longe, from Old English lungen, from Proto-Germanic *lunganjō, an enlargement of *lungô (“the light organ, lung”), from Proto-Indo-European *h₁lengʷʰ-, whence ultimately also light. Cognate with West Frisian long, Dutch long, German Lunge, Danish, Norwegian Bokmål, and Norwegian Nynorsk lunge, Swedish lunga, Icelandic lunga, and also Russian лёгкое (ljóxkoje) (lung), Ancient Greek ἐλαφρός (elaphrós, “light in weight”) and perhaps Albanian lungë (“blister, bulge”). Compare Latin levis and Old English lēoht (Modern English light). See also lights (“lungs”). Superseded non-native Middle English pomoun (“lung”), borrowed from Old French poumon, pomon (“lung”).
