The Quendian languages are a family of diachronic conlangs invented by J. R. R. Tolkien. The Quendian languages are the languages of the Elves of Middle-earth and Aman, and evolved from a common ancestor (Primitive Quendian). The most important branch (and the only branch well documented) is the Eldarin branch, to which belong Quenya, Sindarin and several other languages. The non-Eldarin languages are collectively known as Avarin, but are almost entirely undocumented.
