Caetlin

Caetlin is an English spelling variant of the Irish name Caitlín, itself the Irish form of Katharine, which ultimately derives from the Greek name Aikaterine. The precise root of Aikaterine is debated, but it has long been associated with the Greek word katharos, meaning pure. The name spread widely through medieval Europe largely due to the veneration of Saint Catherine of Alexandria. Related forms include Caitlin, Katelyn, Kaitlyn, and Katherine.
