Kailey

Kailey is an English name that arose as a phonetic respelling of Kaylee or Kayleigh, which themselves derive from the Irish and Scottish Gaelic name Caol, meaning slender, or from the Old English elements cœg, meaning key, combined with leah, meaning woodland clearing. The name gained widespread use in the United States during the late twentieth century as part of a broader trend of elaborated feminine names ending in the -lee sound. It shares the same essential roots and meaning with the spelling variants Kaylee, Kayleigh, Kaylie, and Kailee.
