Kathlyn

Kathlyn is an English variant spelling of Kathleen, which itself derives from the Irish name Caitlín, a Gaelic form of Catherine. Catherine traces back through Latin and Late Greek to the Greek name Aikaterine, whose precise original meaning is uncertain, though it was early associated by folk etymology with the Greek word katharos, meaning pure. The name gained widespread use in the Christian world largely through the veneration of Saint Catherine of Alexandria. Related forms include Katherine, Katelyn, Cathleen, and Kathlynn.
