köken: From Proto-Turkic *čẹr (“rotten, foul; to rot; illness; dirt; to be sick, ill; rot; glue; anguish, sorrow”) whence also Azerbaijani çürümək (“to rot”); alternatively from Persian چرک (čerk). However, it has been proposed that the latter Persian term is a Turkic borrowing itself (ibid.).
köken: From Middle Dutch vuul, from Old Dutch *fūl. The adjective is from Proto-West Germanic *fūl, from Proto-Germanic *fūlaz, the noun from Proto-Germanic *fūlą. Ultimately from Proto-Indo-European *pū-, *pew-. Akin to English foul, German faul, Danish and Swedish ful.
