What is the meaning of the name Kaci ?

The baby name Kaci is a Female name , 2 syllables long and is pronounced KAY-see (IPA: /ˈkeɪsi/).

Kaci is Irish in Origin.

Kaci (pronounced KAY-see) is a modern spelling of Casey, ultimately rooted in the Irish Gaelic surname Ó Cathasaigh, meaning “descendant of Cathasach.” The personal name Cathasach derives from cath (“battle”) with the adjectival suffix -asach, yielding the sense “vigilant, watchful” and by extension “battle-ready.” As with Casey, Kaci functions as a unisex given name, though the K- spellings skew feminine in contemporary usage.

Used as a given name in the English-speaking world since the late 19th century, Casey gained wide currency in America, and creative respellings surged in the late 20th century amid phonetic and initial-K trends. Kaci rose in that period and remains a modern alternative. Close variants include Casey, Kasey, Kacey, Kacie, and Kaycee; initials-styled KC also appears. The name’s meaning centers on alertness and readiness, with connotations of courage from its battle-root. While Kaci is modern in look, it carries the heritage of its parent name.
