Half-elven

In the fiction of J. R. R. Tolkien, the Half-elven (Elvish sing. Peredhel plur. Peredhil), are the children of the union of Elves and Men.

Although there may have been many such, only three are named as "Half-elven":

• Eärendil, son of the Man Tuor[?] and Elf Idril
• Elrond, son of Eärendil and Elwing
• Elros, also son of Eärendil and Elwing

Around the end of the First Age, each was given the choice of kindred to which they wished to belong; Eärendil and Elrond chose the Eldar, and Elros chose to be human.

(Oddly, although Elwing's father was the Man Dior and her mother the Elf Nimloth of Doriath, and the Valar gave her free choice of kindred, she is never called Half-elven.)
