Kaeli is a modern American spelling of Kaylee, a name that was built in the 20th century from the sounds of Kay and Lee and is best read as "a blend of Kay and Lee"; some parents also connect it to the Irish Keeley, meaning "slender". The ae spelling gives the familiar name a Hawaiian look. Kaeli was a rarity for years, then jumped from number 2327 in 2022 straight into the top 1000 at number 679 in 2023; it ranks number 756 in 2025.
