Quenya is a fictional language devised by J. R. R. Tolkien, and used in his fictional universe, Middle-earth. Here is presented a resume of the grammatical rules of late Quenya as established from Tolkien's writings c. 1951–1973. It is almost impossible to extrapolate the morphological rules of the Quenya tongue from published data because Quenya is a fictional and irregular language that was heavily influenced by natural languages, such as Finnish and Latin, not an international auxiliary language with a regular morphology.
