Slender or fair
Kahlen is a modern phonetic variation of the Irish surname Caelan, which is derived from the Gaelic word 'caol' meaning slender. It gained some visibility in the early 2000s due to its use in fantasy literature and reality television. While it has a traditional Celtic root, its current form is largely considered a contemporary American invention.
