Likely a modern blend meaning 'slender' or 'crown'
Kailiyah is a modern American invention, likely created by blending the name Kaia or Kayla with the popular 'liyah' suffix. While it does not have a singular ancient root, it draws phonetic influence from the Gaelic 'caol' meaning slender and the Hebrew 'aliyah' meaning to ascend.
