cassidi is a modern phonetic respelling of Cassidy, used as a unisex given name. It comes from the Irish surname Ó Caiside (“descendant of Caiside”), the personal name Caiside likely deriving from Old Irish cas, “curly” or “twisted,” hence “curly‑haired.” The Ó Caiside were a notable learned family in medieval Fermanagh, serving as poets and physicians.

Pronounced KASS‑ih‑dee, cassidi preserves the name’s Celtic flair while offering a contemporary twist. The core meaning centers on “curly‑haired,” with a broader sense of spirited individuality and family heritage.
