The Qenya Lexicon
The Qenya Lexicon is the first Elvish dictionary written by Tolkien. He included the number '23' in the first page, suggesting it was begun between 1915 and 1916, when he had that age. Many revisions were made until 1919 or 1920. The Lexicon was written along with the Qenyaqetsa, a description of the Qenya phonology, being both works the foundation of the Qenya language, which decades later would become the Quenya.
A great part of the Lexicon was used by Christopher Tolkien in his Appendices of both books of The Book of Lost Tales. In 1998, both Qenyaqetsa and Qenya Lexicon were published in full in Parma Eldalamberon 12.
