grist

From Middle English grist, gryst, from Old English grist, gyrst (“the action of grinding, corn for grinding, gnashing”), of obscure origin: possibly from a pre-Germanic substrate language, or from a derivative of Proto-Germanic *gredaną (“to crunch”), possibly from Proto-Indo-European *gʰer- (“to rub, grind”). Cognate with Old Saxon gristgrimmo (“gnashing of the teeth”), German Griesgram (“a grumbler, a grouch, peevishness, misery”), Old English gristel (“gristle”).
