Languages constructed by J. R. R. Tolkien
The Elvish languages or Eldarin languages are the languages of the Elves. At other times, Elvish languages were the common speech. Later the Elvish languages were also used by humans, especially by scientists and the nobility. The Eldarin languages can be divided into two groups: Quenya language and Telerin languages (which includes Telerin, Nandorin, and Sindarin).
