Meaning & Origin
shovel (for embers), spade
Kaci is a girl's and boy's baby name of Irish origin, a variant spelling of Cassie or Casey, from the Irish Gaelic Cathasaigh, meaning 'vigilant, watchful.' The phonetic K-spelling emerged in the late 20th century as parents sought distinctive variations of this cheerful Irish name.
With nearly 10,000 U.S. births, Kaci has a bright, energetic quality — it captures all the warmth of Casey and Cassie in a spelling that feels distinctly modern and immediately memorable.
