Vigilant or watchful
Kacey is a modern phonetic spelling of the Irish surname Casey, which is derived from the Gaelic 'O Cathasaigh' meaning 'descendant of Cathasach'. The root word 'cathasach' translates to vigilant or watchful. While historically a surname, it gained popularity as a given name in the late 20th century for both boys and girls.
