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 Superseded non-native Middle English pomoun (“lung”), borrowed from Old French poumon, pomon (“lung”).

Where this record stops

This page does not supply an independently verified sound-change sequence, first-use manuscript or complete family tree unless a cited analysis explicitly establishes one. Missing detail here is a limit of this record—not a claim that humanity knows nothing more.

An older meaning does not determine what a word must mean today. Follow the sources, preserve disagreements, and keep ancestry separate from interpretation.
