Kaitlin

Kaitlin is an English spelling variant of Caitlín, the Irish form of Cathleen, which itself derives from Katharine. That name traces back through Latin and Greek to an uncertain ancient root, possibly related to the Greek katharos, meaning pure. The name gained widespread popularity in English-speaking countries during the late twentieth century alongside other phonetic spellings such as Katelyn and Katelynn. Caitlin, Kaitlyn, and Kathleen are among the many related forms sharing the same ultimate origin.
