Fictional Languages

In the imaginary worlds of fantasy or science fiction, fictional languages are a common way for authors to increase the complexity and realism of a created culture and people. Often, these languages serve to demonstrate an important trait of their speakers, and aspiring writers and storytellers can learn by studying the intentionality behind these fascinating creations. Below are some fictional languages alluded to or used in fictional media!

Klingon from Star Trek: Klingon is a fictional language hailing from the renowned sci-fi series Star Trek. Spoken by the Klingons, a group of warrior aliens featuring prominently in Star Trek’s many installments, this language has found a life of its own beyond the fictional confines of its origins. With over thousands of vocabulary words and its very own language institute, Klingon has become a very real linguistic presence!^{[1]

Elvish from The Lord of the Rings: The Elvish languages (there are multiple!) developed by J. R. R. Tolkien for his books have become significant in their own right. As a linguist himself, J. R. R. Tolkien in fact began his stories with the invention of these languages.^{[2]

Simlish from The Sims: Unlike Klingon and Elvish, Simlish, spoken by the virtual people populating the world of the popular video game, is not actually a language with complete vocabulary, grammar, and syntax. Instead, it is more vibes-based, drawing from different languages and the specific intonations of voice actors to bring about the familiar-sounding yet foreign language spoken in The Sims.^{[3]

Na’vi from Avatar: It is no surprise that a film which took full advantage of computer graphics and cutting-edge visual effects to render realistically a fictional world also went the extra mile to construct a language for the Na’vi, the alien species at the center of the narrative. Created by linguist Paul Frommer, the language Na’vi has an extensive vocabulary and complete grammar, with its own learning community that unites fans of the franchise!^{[5]

Kryptonian from Superman: We all know that Clark Kent is the civilian identity of legendary comics hero Superman, but did you know that Superman has another name, Kal-El? Kal-El is Superman’s name in Kryptonian, the language of his home world, Krypton. Though Kryptonian existed only in concept for most of the Superman comics, it has since been standardized into a written alphabet and developed further.^{[6]
