Did You Know?Tolkien had created the Middle-earth languages a few years before he had even started working on 'The Hobbit' or 'The Lord of the Rings', the books in which he has abundantly used these constructed languages.
Many have later worked for creating the rules of usage and grammar of these languages. Even after his death, Tolkien continues to contribute in this process. Many of the writer's works that have been published posthumously have helped all those who are interested in understanding these languages better.
For the enthusiasts of Middle-earth languages, given below is a list of websites that provide tools that will assist in online elvish translations.
