The Elvish languages of Middle-earth, constructed by J. R. R. Tolkien, include Quenya and Sindarin. These were the various languages spoken by the Elves of Middle-earth as they developed as a society throughout the Ages. In his pursuit for realism and in his love of language, Tolkien was especially fascinated with the development and evolution of language through time. Tolkien created two almost fully developed languages and a dozen more in various beginning stages as he studied and reproduced the way that language adapts and morphs. A philologist by profession, he spent much time on his constructed languages. In the collection of letters he had written, posthumously published by his son, Christopher Tolkien, he stated that he began stories set within this secondary world, the realm of Middle-earth, not with the characters or narrative as one would assume, but with a created set of languages. The stories and characters serve as conduits to make those languages come to life. Inventing language was always a crucial piece to Tolkien's mythology and world building. As Tolkien stated:
Tolkien created scripts for his Elvish languages, of which the best known are Sarati, Tengwar, and Cirth.
J. R. R. Tolkien began to construct his first Elvin tongue c. 1910–1911 while he was at the King Edward's School, Birmingham and which he later named Quenya (c. 1915). At that time, Tolkien was already familiar with Latin, Greek, Italian, Spanish, and several ancient Germanic languages, Gothic, Old Norse and Old English. He had invented several cryptographic codes such as Animalic, and two or three constructed languages including Naffarin. He then discovered Finnish, which he described many years later as "like discovering a complete wine-cellar filled with bottles of an amazing wine of a kind and flavour never tasted before. It quite intoxicated me." He had started his study of the Finnish language to be able to read the Kalevala epic.
The ingredients in Quenya are various, but worked out into a self-consistent character not precisely like any language that I know.
