エルフ語
Although the Elvish languages Sindarin and Quenya are the most famous and the most developed of the languages that Tolkien invented for his Secondary World, they are by no means the only ones. They belong to a family of Elvish languages, that originate in Common Eldarin, the language common to all Eldar, which in turn originates in Primitive Quendian, the common root of Eldarin and Avarin languages.
