Origin of cool

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