Arwen

Arwen means "Noble Maiden" in Sindarin (from ara- = "noble" and gwenn = "maiden"). The Quenya form of her name is not entirely certain, but as just a name, it is grammatically possible to calque Arwen to Quenya as Aranwen (pron. [aˈranwen] using aran- and wendë, stem Aranwend-; compare masculine Aranwë), but Arwen itself is also coincidentally a valid Quenya synthesis (using ar-, stem Arwend-), meaning the possibility that Arwen's name is the same in Sindarin and Quenya. Her epessë, Undómiel, means "Evenstar", from Undómë "evening twilight" and el "star".
