foul

Definition

Covered with, or containing unclean matter; dirty.

Etymology

Inherited from Middle English foul, from Old English fūl (“foul, dirty, unclean, impure, vile, corrupt, rotten, stinking, guilty”), from Proto-West Germanic *fūl, from Proto-Germanic *fūlaz (“foul, rotten”), from Proto-Indo-European *puH- (“to rot”). Cognate with Dutch vuil (“foul, dirty, filthy, obscene, lewd”), German faul (“foul, rotten, putrid, lazy”), German Low German fuul (“foul, rotten, putrid”), Faroese fúlur (“foul”), Icelandic fúll (“foul, rotten, sullen”), Danish ful (“nasty, ugly”), Norwegian Bokmål ful (“clever, sly”), and Swedish ful (“ugly, dirty, bad”), 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.
