Kaitlyn is a girl's name of English origin, traditionally used in Christian families. The name means "Pure, an English respelling of the Irish Caitlin, which descends through Old French Cateline from Greek katharos (clean, unblemished). The phonetic K-spelling arose as English-speaking parents reshaped the Gaelic original, and its bright two-syllable rhythm made it emblematic of a wave of similarly invented forms." and belongs to the Light cluster — names meaning radiance, illumination, and hope.
