While J.R.R. Tolkien is often compared to modern 'conlangers' like Mark Rosenfelder, his distinction lies in the fact that he didn't create languages to serve his stories—he created the world of Middle-earth to provide a home for his linguistic systems. Within Tolkien's archives, the vocabulary and grammatical evolution of Elvish tongues like Quenya and Sindarin are robust enough to constitute a 'real' academic study. In contrast, while contemporary creators can use AI to churn out dozens of languages rapidly, Tolkien’s profound linguistic depth, built with only pen and paper in the mid-20th century, remains the 'Everest' of both linguistics and fantasy literature.
