Narrow or slender
Cylan is likely a modern variant of the Welsh name Dylan or the Gaelic name Caolán. In its Gaelic roots, it stems from 'caol', meaning narrow or slender, often referring to a narrow body of water or a thin person. It has gained some traction as a unique alternative to more common 'C' names like Caleb or Colin.
