Kaitlyn

Kaitlyn is a modern English spelling variant of Caitlin, which is the Irish form of Catherine. Catherine itself derives from the Greek name Aikaterine, whose meaning is debated but has long been associated with the Greek word katharos, meaning pure. The name became widespread in Ireland through medieval devotion to Saint Catherine of Alexandria and later gained broad popularity across the English-speaking world in various spellings. Related forms include Katelyn, Caitlyn, Katelynn, and Kathleen.
