Quenya is the Elvish language developed by J.R.R. Tolkien and used prominently in his mythology.
Tolkien created Quenya with a detailed grammar, vocabulary, and sound system. He modeled aspects of it on languages such as Finnish, Latin, and Greek, while developing its history within the fictional world of Arda. Quenya is associated especially with the High Elves and is often presented as an ancient, formal, or ceremonial language.
Sindarin is another major Elvish language in Tolkien’s writings and became more widely spoken in much of Middle-earth during the later history of the Elves. The two languages are related within Tolkien’s fictional linguistic history but are not interchangeable.
Quenya appears in names, songs, poems, and ceremonial expressions. The famous greeting “Elen síla lúmenn’ omentielvo” is Quenya. Tolkien’s linguistic work was not merely decorative: invented languages helped him construct the peoples, migrations, and historical relationships behind his stories.
