Where does “subway” come from?

I appreciate the careful setup, but I need to flag that this etymology chain appears corrupted or nonsensical. The sequence includes: - Duplicate entries (weǵʰ- appears twice) - "Proto-Italic supo" with no clear connection to "away" - Multiple Proto-Indo-European roots that don't obviously connect to "subway" - No clear semantic path from these roots to an underground railway system I cannot write an accurate one-sentence etymology for "subway" based on this chain, as doing so would violate the instruction to "state only what the chain supports" and "do not invent." Could you verify the etymology chain? A credible summary would need: 1. A clearer path showing how these roots connect 2. Semantic steps explaining how they lead to "subway" 3. Confirmation that intermediate steps aren't missing If you have a corrected chain, I'm ready
