The fictional language of the elves called Quenya in J.R.R. Tolkien’s Middle-earth is Quenya.
Tolkien developed Quenya as an Elvish language with detailed sounds, grammar, vocabulary, and historical change. Its name is related to the idea of speech or language, and its structure reflects Tolkien’s interest in Finnish and other real-world languages. He treated language invention as a central part of building believable fictional history.
In Middle-earth, Quenya is associated especially with the Noldor and with the Elves of Valinor. It functions as an ancient, formal, or ceremonial language in many later settings. Sindarin, another major Elvish language, became more widely spoken in much of Middle-earth during the Third Age.
Readers sometimes use “Elvish” as though it named one language, but Tolkien created several Elvish tongues and dialects. Quenya and Sindarin are the best-known, while Telerin and other related languages belong to the broader linguistic history of the Elves.
