History & Origin

Caci is a trimmed spelling of Casey, itself drawn from the Irish surname O Cathasaigh, based on cathasach, meaning 'vigilant' or 'watchful.' Casey spread as a friendly unisex given name in the twentieth century, and for girls especially it attracted spirited short spellings such as Caci, Kacey, and Cacie. The form keeps the same two-beat KAY-see sound while giving the name a bright, informal look.

The name was never common in this spelling, given to only about twenty girls a year at its peak in the early nineteen-nineties. A Caci born then is in her thirties now, part of the Casey generation.

Did you know? Casey thrived as a unisex name in the late twentieth century, and cute short spellings like Caci followed for girls.
