Where does “po” come from?

I need to work through this carefully, as the chain seems problematic. Looking at the chain provided: - English pot | Middle English pot | Latin pavo | Latin pavo | Ancient Greek ταώς | Latin potens | Latin potens | Latin possum This chain has issues: 1. It jumps from Latin pavo (peacock) to Ancient Greek ταώς (peacock) - these are related but the chain doesn't show clear directionality 2. Then it inexplicably jumps to Latin potens/possum (powerful/able) - which are completely unrelated to pavo/peacock 3. The headword is "po" but the chain starts with "English pot" The chain as given is incoherent and contradictory. I cannot write an accurate etymology sentence from this data because: - The chain conflates two unrelated etymological paths (pavo/peacock

po (English): A peacock; A chamberpot
