Meaning and origin of Kaylin
Kaylin is an American (modern coinage) name that is usually said to mean “modern coinage; blend of Kay and Lynn”.
Kaylin is a modern American name, generally seen as a blend of Kay and Lynn or as a variant of Kaylee and Caitlin. Caitlin itself is the Irish form of Catherine, but Kaylin is usually chosen for its sound rather than its roots. It became popular in the late twentieth century, when names with the Kay- beginning were widely used. The name is bright, friendly and easy to say, with two simple syllables. Spellings such as Kaylyn, Kailyn and Kaelyn are also common. Kay is a natural nickname.
