Slender or narrow
Kelin is a modern variant of the Irish name Caelan or the Gaelic CaolΓ‘n. It is derived from the word 'caol', which refers to slenderness or a narrow physical form. While historically masculine in its original forms, Kelin is used as a gender-neutral option in contemporary English-speaking contexts.
