### Etymology

From Middle English crome, cromme, crumme, crume, from Old English cruma (“crumb, fragment”), from Proto-Germanic *krumô, *krūmô (“fragment, crumb”), from Proto-Indo-European *grū-mo- (“something scraped together, lumber, junk; to claw, scratch”), from *ger- (“to turn, bend, twist, wind”). The b is unetymological, as in limb, appearing in the mid-15th century to match crumble and words like dumb, numb, thumb. Cognate with Dutch kruim (“crumb”), Low German Krome, Krume (“crumb”), German Krume (“crumb”), Danish krumme (“crumb”), Swedish dialectal krumma (“crumb”), Swedish inkråm (“crumbs, giblets”), Icelandic krumur (“crumb”), Latin grūmus (“a little heap”).
