Inherited from Middle English ffoul, foul, foull, fowel, fowle, fuyle, voul, vul, 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- (“foul, rotten”). Cognates Cognate with Central Franconian fuul (“putrid, rotten; lazy, workshy”), Cimbrian baul, vaul (“putrid, rotten”), Dutch vuil (“dirty, foul; lewd, obscene; dishonorable; illegal”), German faul (“foul, putrid, rotten; lazy”), Yiddish פֿױל (foyl, “putrid; lazy”), Danish ful (“nasty, ugly”), Icelandic fúll (“foul, rotten, sullen”), Norwegian Bokmål and Norwegian Nynorsk ful (“clever, sly”), and Swedish ful (“ugly; bad, dirty”), Gothic 𐍆𐌿𐌻𐍃 (fuls, “fetid, foul, putrid”), and through Indo-European, with Latin puter (“decaying, rotten; friable, crumbling”), Greek πύο (pýo), πύον (pýon, “pus”), Albanian fëlliq (“to make dirty, sully”), Latvian pūt (“to rot”), Lithuanian pūti (“to rot”), Armenian փուտ (pʻut, “rottenness”), Persian پوده (pude, “rubbed, worn; foul, rotten; empty, hollow”), Sanskrit पूयति (pūyati, “to become foul; to stink”). 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.
Inherited from Middle English foulen, fulen, from Old English fūlian (“to become foul; rot; decay”), from Proto-West Germanic *fūlēn, from Proto-Germanic *fūlāną (“to rot; decay”).
