Kaylani is a modern American name created on the pattern of Hawaiian names such as Kalani and Kehlani; the element lani means "heavenly" or "sky", so the name is usually read as "the heavens". The Kay- opening links it to Kaylee and Kayla, which is why it feels familiar at first hearing. Kaylani is one of the fastest climbers of the last decade: it entered the US top 1000 in 2016 and rose from number 1054 in 2015 to number 185 in 2025, its best rank so far.
