Caetlin

Caetlin is an English spelling variant of Caitlin, itself the Irish form of Katherine, which derives from the Greek name Aikaterine. The ultimate root of Aikaterine is debated, with proposed connections to the Greek word katharos, meaning pure, though earlier forms of the name may predate that association. Caitlin gained widespread use in the English-speaking world during the twentieth century, and variant spellings such as Caetlin, Katelyn, and Kaitlyn arose as the name spread beyond its Irish origins.
