Caetlin

Caetlin is an anglicized spelling variant of the Irish name Caitlín, itself the Hiberno-Norman adaptation of the Old French Cateline, which derived from the Latin Katerina and ultimately from the Greek Aikaterine, a name whose precise root remains debated but is often associated with the Greek katharos, meaning pure. It entered Ireland through Anglo-Norman influence in the medieval period and became deeply naturalized in Irish culture. The name belongs to the same broad family as Katherine, Catherine, Caitlin, Katelyn, and Kaitlyn, all of which trace the same linguistic chain across different languages and eras.
