giblets (n.)

"edible entrails of a fowl, parts removed or trimmed from a fowl when it is prepared for roasting," mid-15c. (in singular, gybelet), earlier "unnecessary appendage" (c. 1300), from Old French gibelet "game stew," a cookery word of uncertain origin; perhaps from Frankish *gabaiti "hunting with falcons," related to Old High German beizan "to fly a falcon," literally "to cause to bite," from bizzan "to bite," from PIE root *bheid- "to split," with derivatives in Germanic referring to biting.
