Caelen

Caelen is a masculine name of Gaelic origin, considered a variant spelling of Caelan or Kaelan. The name derives from Celtic roots meaning "slender" or "powerful in battle." Some sources also connect it to the Gaelic word for "companion." The spelling with 'ae' creates a distinctive look while maintaining the traditional pronunciation (KAY-len).
