Etymology
From Middle English cheterlingis, chitterling, chitterlynge, chytyrlynge, ultimately from Proto-Germanic *kūtiz, *kut-, from Proto-Indo-European *gud-, *gewd- (“intestine, gut”), from *gʷu-, *gū- (“to bend, curve, bow, camber, vault, distend”). Compare Middle Low German kǖtel (“entrails, tripe”), German Kutteln (“tripe”) and Scots kyte (“belly, stomach”). Compare also Icelandic kviður (“stomach”).
