What does the name Kaytlin mean?
Kaytlin is a spelling of Kaitlyn, pronounced the same way, so it shares Kaitlyn's meaning and origin.
Kaitlyn is one of the modern American spellings of Caitlin, which Wiktionary describes as the Irish equivalent of Catherine. Irish Caitlín came from Old French Cateline, reshaped with the Irish diminutive ending -ín. Catherine itself goes back to Greek Aikaterine, which DMNES calls of uncertain origin; the link with Greek katharos, pure, is a later association that DMNES rejects. US records show Kaitlyn from the early 1970s, with its peak around 2000.
Caitlín (Irish, “Catherine”)Αἰκατερίνη (Ancient Greek, “Katherine (origin uncertain)”)
How sure is this? Uncertain. Meaning only through Catherine, whose origin DMNES calls uncertain.
Other explanations you may read: Means 'pure' (Greek katharos). DMNES says Katherine is unrelated to that word..
Related names: Caitlin, Katelyn, Catherine, Kate, Katie.
