Quenya was J.R.R. Tolkien’s private language created from Finnish and other influences.
Tolkien developed Quenya as one of the principal languages of the Elves. Its sound and grammar were influenced especially by Finnish, as well as by other languages Tolkien knew or studied. In the fiction, Quenya is associated with the High Elves and has an elevated, literary status comparable to a classical language.
Quenya is often confused with Sindarin, another major Elvish language. Sindarin was the everyday language of many Elves in Middle-earth during the later histories, while Quenya retained a more formal and ancient role. Tolkien continued refining his invented languages throughout his life, so published forms sometimes reflect different stages of his evolving ideas rather than a single fixed project.
