Eiden

Eiden is a modern spelling in the Aidan family, ultimately connected with Irish Aodhán. The older name combines a fire-related element with a diminutive ending, giving the familiar interpretation “little fire.” The E spelling changes the appearance without supplying a new meaning separate from that name family.

Aidan and Aiden are the closest familiar alternatives, while Aodhán preserves the Irish written form. Parents may choose Eiden to follow an initial-letter pattern or to distinguish an honor name visually. It should not be confused with Eden, which has a different history and usually a different first vowel in English. Saying both names aloud makes that distinction clearer.
