Where does “gunpowder” come from?

I need to flag a significant issue with this chain: it doesn't support the word "gunpowder" etymologically. The chain provided traces: English gunpowder → English gunna → English gonna → Latin pulvis (powder) → Proto-Indo-European pel- However, this chain is problematic because: 1. "Gunna" and "gonna" are not established etymological steps for "gunpowder" 2. The connection between "gun" and "gunna/gonna" is unclear 3. The chain appears corrupted or fictional I cannot write an accurate one-sentence origin summary for "gunpowder" using this chain, as doing so would violate the rule to "state only what the chain supports" and would require me to invent or validate a connection that doesn't reflect genuine etymology. **Could you verify the chain?** The actual etymology of "gunpowder" involves:

gunpowder (English): An explosive mixture of saltpetre (potassium nitrate), charcoal and sulfur; formerly used in gunnery but now mostly used in fireworks
