Alert, vigorous, or from the forest
Kaysi is a modern phonetic spelling of the Irish surname Casey, derived from the Gaelic 'Cathasaigh' meaning vigilant or watchful. It may also be used as a diminutive of the name Katherine or as a variation of the name Acacia, which refers to a type of tree. In recent years, it has emerged as a creative spelling choice for parents seeking a familiar sound with a unique visual flair.
