From Middle English foul, from Old English fūl (“foul, unclean, impure, vile, corrupt, rotten, guilty”), from Proto-West Germanic *fūl, from Proto-Germanic *fūlaz (“foul, rotten”), from Proto-Indo-European *puH- (“to rot”).

Cognate with Dutch vuil (“foul”), German faul (“rotten, putrid”), Danish and Swedish ful (“foul”), and through Indo-European, with Albanian fëlliq (“to make dirty”), Latin puter (“rotten”). More at putrid.

Ancient Greek φαῦλος (phaûlos, “bad”) is a false cognate inasmuch as it is not from the same etymon, instead being cognate to few.
