Meaning & origin
Kaily first entered U.S. records in 1983, a relatively late debut compared to many traditional names. Its peak year was 2010, after which it has been on a declining trajectory, falling since 2011. The name is most commonly found in California, the top state for births. While never among the most popular names, it reflects the naming trend of creating unique spellings of established names like Kaylee.
Kaily is a contemporary spelling variant of Kaylee, which itself emerged in the late 20th century as a feminization of the Irish surname Caollaidhe. The name may also be influenced by the Gaelic word 'caol', meaning 'slender' or 'narrow'. Its popularity rose sharply in the United States during the 1990s and 2000s.
