Caitlyn

Caitlyn is an anglicized spelling variant of the Irish name Caitlín, itself the Irish form of Catherine, which traces back through Old French Katerine to the Latin Catharina and ultimately the Greek Aikaterinē. The precise root of the Greek name remains debated, with proposed connections to the Greek katharos, meaning pure, being the most widely accepted folk etymology. Caitlyn rose to popularity in English-speaking countries, particularly in the United States, during the late twentieth century as an elaborated spelling of Caitlin. Related forms include Kaitlyn, Kaitlin, Katelyn, and the traditional Catherine.
