Quenya is the high-elven language developed by J.R.R. Tolkien and associated especially with the Noldor.
Tolkien constructed Quenya as part of the linguistic history of Middle-earth. It is descended from Valarin-influenced early Elvish and was shaped by the Eldar who traveled to Aman. The Noldor preserved and used it as a language of lore and ceremony, while Sindarin became more widely spoken among many Elves in Middle-earth.
The language’s name is often translated as “speech” or connected with the idea of speaking. Tolkien designed its sound and structure with inspiration from languages including Finnish, but Quenya is not Finnish and has its own grammar, vocabulary and fictional history.
Sindarin is another major Elvish language and is more prominent in many spoken conversations in The Lord of the Rings. Khuzdul is the secret language of the Dwarves, while the Black Speech was created for servants of Sauron. Those languages are therefore distinct from Quenya.
