From Middle English colen, from Old English cōlian (“to cool, grow cold, be cold”), from Proto-West Germanic *kōlēn (“to become cold”), from Proto-Indo-European *gel- (“to freeze”). Cognate with Dutch koelen (“to cool”), German kühlen (“to cool”), Swedish kyla (“to cool, refrigerate”). Also partially from Middle English kelen, from Old English cēlan (“to cool, be cold, become cold”), from Proto-West Germanic *kōlijan, from Proto-Germanic *kōlijaną (“to cool”), altered to resemble the adjective cool. See keel.
