Arwen is a name **invented by J.R.R. Tolkien in Sindarin — the Elvish language of his Middle-earth legendarium** — from ar (noble, royal) + gwen (maiden). **Arwen Undómiel ("Evenstar") — daughter of Lord Elrond of Rivendell, granddaughter of Lady Galadriel, beloved of Aragorn, and last Queen of the Reunited Kingdom in *The Lord of the Rings***. **In a profound choice of love over immortality, she relinquished the immortality of the Elves to wed Aragorn, dying of grief at Lothlórien after his passing**. **Portrayed by Liv Tyler in Peter Jackson's film trilogy (2001-2003)**. The name's US use began modestly after the films and has grown steadily.
Featured throughout Tolkien's *The Lord of the Rings* (1954-55) and *The Silmarillion* (1977).
Arwen reduces to nine — the number of Evenstar.
