Where does “mealy” come from?

I need to work through this etymology chain carefully, but I notice there's a significant problem: the chain provided (meal, mole, moll, Moll, Mary, Latin -ia, PIE -kos, PIE -kos) doesn't logically lead to "mealy."

Given the instruction to "state only what the chain supports" and not invent steps, I cannot construct an accurate one-sentence etymology from this chain as presented. The chain itself seems corrupted or mislabeled for the headword "mealy." I should note: **I cannot responsibly write the summary sentence because the etymology chain provided does not support a coherent deriv
