Origin: Irish

Meaning: Slender; Mighty warrior

Kael is an Irish boy’s name most commonly derived from the Irish word coal, meaning “slender.” While this meaning might not evoke images of a fearsome warrior, Kael is actually the modern, Anglicized spelling of the ancient Irish name Cáel, a mythological figure who was a member of Fionn mac Cumhaill’s warrior band, the Fianna. Cáel was the son of a King and was said to have drowned during a seventeen-day battle to defend Ireland from European invaders. Kael is also linked to the Irish name Kellen, meaning “might warrior.” It is a great choice if you have Irish ancestry or if you want to give baby a name he’ll be proud of. While it might make some think of the green leafy vegetable, you’ll know that baby Kael is really the name for a legendary soldier.
