Katelin

Katelin is a modern English spelling variant of Katelyn, itself an anglicized form of the Irish name Caitlín, which derives from Catherine. Catherine ultimately traces back to the Greek name Aikaterinē, whose precise root is debated but has long been associated with the Greek word katharos, meaning pure. The name gained widespread use in the English-speaking world through medieval veneration of Saint Catherine of Alexandria. Related forms include Caitlin, Kaitlyn, Katelyn, and Kathleen.
