History & Origin

Kaci comes from Berber, the language family of North Africa, with the meaning 'vigilant' or 'watchful'. The streamlined spelling reads as contemporary while resting on that older root. American pop singer Kaci Battaglia and nurse Kaci Hickox both carry the name in the United States.

In English the name overlaps in sound with Casey and Kacey, names of separate origin that land on the same pronunciation. That convergence gives Kaci a familiar ring even where its Berber source is less known.

Did you know? Kaci is a spelling variant of Casey, so it keeps the same core meaning of 'vigilant' while changing the visual style.
