History

Etymology

From Middle English kele, from Old Norse kjǫlr, itself from Proto-Germanic *keluz, of uncertain origin. Displaced Old English ċēol from a related root. Distantly related to kile.

From Middle English kelen, from Old English cēlan (“to cool, to make or become cool”), from Proto-West Germanic *kōlijan, from Proto-Germanic *kōlijaną (“to cool”). Cognate with Saterland Frisian käile, köile (“to cool”), Dutch koelen (“to cool”), German Low German köhlen (“to cool”), German kühlen (“to cool”), Danish køle (“to cool”), Icelandic kæla (“to cool”).

Probably from Scottish Gaelic cìl (“ruddle”).

Compare Scots kele, keil, keill (“to put to death, kill”).
