Slender, pure, or keeper of the keys
Caylan is a modern phonetic variant likely derived from the Irish name Caelan, meaning slender, or influenced by the Greek name Catherine, meaning pure. It is often used as a contemporary blend of the popular 'Cay' prefix and 'lan' suffix. In some contexts, it is also associated with the Welsh name Cai, meaning keeper of the keys.
