Esperanto in Sci-Fi: A Brief History
Esperanto, the constructed language designed for global communication, has found an unexpected home in science fiction. Its neutral, easy-to-learn structure makes it a natural fit for futuristic settings where humanity has moved beyond national languages. The most famous example is Star Trek, where Esperanto was briefly considered as the language of the United Federation of Planets before being replaced by English for practical reasons.
Other sci-fi works have embraced Esperanto more fully. The 1966 film Incubus was entirely shot in Esperanto, adding an eerie, otherworldly feel to its demonic storyline. More recently, the Netflix series The OA used Esperanto as a mystical language bridging dimensions.
Why Sci-Fi Loves Esperanto
Sci-fi often imagines a future where humanity is united, and Esperanto fits that vision perfectly. Its lack of native speakers means no single culture dominates it, making it an ideal candidate for a universal auxiliary language. Some key reasons sci-fi writers favour Esperanto:
- It sounds futuristic yet familiar, with roots in European languages.
- Its simplicity makes it plausible as a lingua franca for space colonies.
- It avoids political baggage tied to real-world languages.
Esperanto and Space Communication
Beyond fiction, Esperanto has been seriously proposed as a language for interstellar communication. In the 1970s, NASA included Esperanto in its Pioneer plaques and Voyager Golden Records as a potential bridge language for extraterrestrial contact. While this never materialised, the idea persists among some linguists and space enthusiasts.

Esperanto’s Future in Sci-Fi and Beyond
As space exploration advances, the question of a universal language becomes more pressing. While English dominates now, Esperanto remains a compelling alternative for fiction - and perhaps reality. Its role in sci-fi reflects humanity’s desire for unity, whether on Earth or among the stars.
