In the module Tolkien’s Invented Languages in The Lord of the Rings, we exclusively looked at Tolkien's language invention from the perspective of how the languages were used in The Lord of the Rings. In this follow-on module, we will explore the linguistic information in The Road Goes Ever On, The Silmarillion, The History of Middle-earth, the Letters, as well as publications such as Parma Eldalamberon and Vinyar Tengwar. If you've ever wanted to get a handle on the primary sources for information about Tolkien's invented languages beyond The Lord of the Rings, this is the module for you!
