<P> While the Elvish languages remained at the center of Tolkien's attention, the requirements of the narratives associated with Middle - earth also necessitated the development at least superficially of the languages of other races, especially of Dwarves and Men, but also the Black Speech designed by Sauron, the main antagonist in The Lord of the Rings . This latter language was designed to be the ostensible antithesis of the ideal of an artistic language pursued with the development of Quenya, the Black Speech representing a dystopian parody of an international auxiliary language just as Sauron's rule over the Orcs is a dystopian parody of a totalitarian state . </P> <P> The Elvish language family is a group of languages related by descent from a common ancestor, called the proto - language . The family was constructed from c. 1910 . Tolkien worked on it up to his death in 1973 . He constructed the grammar and vocabulary of at least fifteen languages and dialects in roughly periods: </P> <Ul> <Li> 1910--c. 1930: Primitive Quendian the proto - language, Common Eldarin, Quenya and Goldogrin . </Li> <Li> c. 1935--1955: Goldogrin had significantly changed and was now Noldorin, joined by Telerin, Ilkorin, Doriathrin and the Avarin . </Li> <Li> The late and mature stage dispensed with Ilkorin and Doriathrin . Noldorin matured into Sindarin . </Li> </Ul> <Li> 1910--c. 1930: Primitive Quendian the proto - language, Common Eldarin, Quenya and Goldogrin . </Li>
