What does the name Cailey mean?

Cailey is a spelling of Kaylee, pronounced the same way, so it shares Kaylee's meaning and origin.

Kaylee is a late-20th-century coinage. Wiktionary gives two explanations: a combination of Kay and Lee, or a variant of the surnames Cayley or Keeley. Wikipedia describes it as a modern English blend of Kay and Lee. It became popular in the US in the 1990s and 2000s, with many spellings such as Kailey and Kayleigh. Because it was made for its sound, it has no single meaning.

How sure is this? Not documented. A modern blend (Kay + Lee) or a surname variant; no meaning of its own.

Related names: Kayleigh, Kailey, Kaylie, Caylee, Kylie.
