Slender or narrow; a modern variant of Kyle or Cillian.
Kylyn is a contemporary American invention, likely created by blending the phonetic elements of the Scottish name Kyle with the popular 'lyn' suffix. It may also be viewed as a creative spelling of the Irish name Cillian, which means 'slender' or 'little church'. As a modern coinage, its specific meaning is often tied to these traditional roots.
