Slender or narrow; a modern invented name.
Kylinn is a modern American invention, likely created by blending the popular prefix 'Ky-' (as seen in Kyle or Kylie) with the suffix '-linn' or '-lynn'. While it lacks a singular ancient root, it is often associated with the Gaelic word 'caol', meaning slender or narrow, which is the basis for the name Kyle.
