Quenya is the fictional language created by J.R.R. Tolkien that was strongly influenced by Finnish.
Tolkien developed Quenya as a language of the Elves, especially the High Elves of Valinor. Its sound patterns and grammatical structure reflect his admiration for Finnish, while its vocabulary and history belong to his invented mythology rather than to Finland itself.
Quenya is often called High-elven or Eldarin in Tolkien's writings. Sindarin, another major Elvish language, was influenced more strongly by Welsh. Tolkien treated his languages historically, giving them related forms, sound changes, and stages of development. This linguistic depth helped make Middle-earth feel like a world with its own long cultural history.
