Arwen

Arwen is best known through J. R. R. Tolkien's The Lord of the Rings. In his constructed Elvish language Sindarin, the name is understood as “noble maiden.” Its Welsh-like sound reflects the linguistic influences behind Tolkien's work, but a fictional-language meaning should be distinguished from a direct translation in everyday Welsh.

Arwen's two syllables make it concise despite its substantial literary background. Arwyn and Arianwen have similar Welsh-looking forms, yet they should not simply be treated as interchangeable spellings of Tolkien's character. The name can carry a clear connection with the books while remaining easy to use in full, without depending on a nickname or an elaborate formal version.
