Meaning & origin
Kaylinn is a modern American coinage that first appeared on the U.S. Social Security records in 1989. It belongs to the family of names ending in the popular -lyn suffix, which saw a surge in the late 20th and early 21st centuries. Its peak year was 2014, when it reached its highest rank, though it has been declining in use since 2010. As of 2025, it ranks 14,942, with a rarity of about 1 in 321,453 births. The name is constructed from Kay (often a short form of Katherine or a phonetic element) and Lynn (from Welsh 'lake'), though as a blend it carries no specific meaning. Kaylinn has not been recorded in any top state lists, indicating its use is scattered across the country. Its appeal lies in its modern, melodic sound and the familiar -lyn ending, common among names like Kaylyn and Hailey. While not historically rooted, it fits a contemporary naming pattern of inventiveness and phonetic appeal.
