Where does “Luftwaffe” come from?

I need to flag a critical issue: the etymological chain provided appears corrupted or nonsensical. It traces "Luftwaffe" (air force) back through "Luft" (air), but then jumps to Proto-Germanic *wēpną and Proto-Indo-European roots (*wēbnom, *lewp-, *lew-) that have no semantic connection to "air" or "weapon." These roots don't explain how we get from "Luft" to "Waffe" (weapon), nor do they support the meaning of either component. A legitimate chain would need to show: - Luft ← air-related roots - Waffe ← weapon-related roots Without a corrected chain, I cannot write an accurate one-sentence summary per your rules, which require naming "every language in the chain in order" and stating "only what the chain supports." **Could you

Luftwaffe (English): The German air force, especially during the Second World War
