J.R.R. Tolkien created Quenya as an Elvish language associated with the elves of Valinor.
Quenya is one of Tolkien’s most developed constructed languages. Within his mythology, it was spoken by the Ñoldor and the Vanyar, two Elvish groups connected with Valinor. Tolkien based much of its sound and structure on Finnish, while also shaping it according to his own historical and aesthetic principles.
The language’s fictional history is important. Quenya was brought back to Middle-earth by exiled Ñoldorin elves, but its use later became formal and literary rather than an everyday vernacular in many regions. This helps explain why it appears in ceremonial names, poetry, titles, and inscriptions.
Quenya is often confused with Sindarin, another major Elvish language. Sindarin became the commonly spoken Elvish language of much of Beleriand and later Middle-earth. Khuzdul is the secret language of the dwarves, while Adûnaic is associated with Númenor. These languages belong to different peoples and linguistic traditions.
