Meaning and origin of Caelan
Caelan is an Irish name that is usually said to mean “variant of Caolán, slender”.
Caelan is an anglicized spelling of the Irish name Caolán, from caol, meaning slender, with a diminutive ending, so it is usually translated as "slender" or "slim lad." Several early Irish saints bore the name Caolán. The spelling Caelan also recalls the Latin caelum, sky, though that is a coincidence of spelling rather than a shared origin. It is usually pronounced KAY-luhn, though some say KEE-lan, closer to the Irish. It fits the family of modern-sounding Irish names like Keelan, Kellan and Callan, and it is sometimes chosen as a less common alternative to Kellan.
