What is the meaning of the name Kassadie ?

Kassadie is English in Origin.

Kassadie is a modern American respelling of Cassidy, itself from the Irish surname Ó Caiside. The Gaelic personal name Caiside likely derives from cas, meaning “curly(-haired),” yielding the sense “descendant of the curly‑haired one.” Pronounced KASS-uh-dee, the K-initial and -ie ending reflect contemporary preferences for phonetic, approachable spellings while preserving the name’s Celtic roots.

Adopted as a given name in the late 20th century, Cassidy gained broad recognition across the English-speaking world and skews feminine in the U.S., though it remains unisex. Kassadie is a rare, stylized offshoot alongside Kassidy, Kasidy, Cassadee, and Kassidee. The -adie finish, echoing names like Sadie, softens the rhythm while keeping the Irish lineage intact. Though seldom appearing in national rankings, Kassadie belongs to the wider Cassidy/Kassidy cluster that peaked in the 1990s–2000s and continues in light contemporary use.
