Caitlyn

Caitlyn is an anglicized spelling variant of the Irish name Caitlín, itself the Irish form of Katherine, which derives from the Greek name Aikaterine, whose meaning is debated but is often linked to the Greek word katharos, meaning pure. The name entered Ireland through medieval French influence, carried by the form Cateline. Caitlyn became particularly popular in the late twentieth and early twenty-first centuries in English-speaking countries as a fashionable respelling. Related forms include Caitlin, Katelyn, Kaitlyn, and Katherine.
