Where does “pothole” come from?

I need to work through this chain carefully, but I notice there are some issues with it that make me unable to write an accurate sentence. The chain provided has logical problems: - "hole" and "pot" are listed as separate Middle English entries, but the chain doesn't explain how they combine into "pothole" - "Latin oleum" appears twice - The sequence jumps between languages inconsistently (English → Middle English → Old English → Middle Dutch → Latin → Ancient Greek → Latin → Proto-Indo-European) - The Proto-Indo-European entry "-kos" doesn't clearly connect to the preceding Latin oleum - The meaning chain (relating to oil) doesn't obviously lead to "pothole" (a hole in a road) Given the instruction to "state only what the chain supports" and not to invent steps, I cannot reliably construct an accurate etymology sentence from this chain. The chain itself appears corrupted
