Quenya is the fictional language J.R.R. Tolkien developed with strong inspiration from Finnish for his Middle-earth mythology.
Tolkien studied Finnish and admired its structure and sound, using it as one influence on Quenya. He created the language as part of a much larger project involving the histories, peoples, and languages of Middle-earth. Quenya is associated especially with the High Elves and is often described within the fiction as an ancient or formal language.
Quenya is not simply a code used to translate English names. Tolkien built vocabulary, grammar, sound patterns, and historical development for it, and he revised these elements throughout his life. The language appears in names, poems, greetings, and ceremonial phrases in his writings.
Sindarin is the major Elvish language most commonly spoken in the later Third Age, while Khuzdul is associated with the Dwarves and Adûnaic with the Númenóreans. These languages can be connected in Tolkien’s linguistic history, but they are distinct from Quenya.
