Science fiction languages are constructed languages, or "conlangs," created for fictional worlds in literature, film, and television. These languages often enhance the depth of the story and provide a sense of realism to alien cultures or futuristic societies. Examples include Klingon from the Star Trek franchise and Dothraki from Game of Thrones. These languages can vary in complexity, with some featuring extensive grammar and vocabulary, while others may be simpler. They often reflect the culture and values of their speakers, making them an integral part of world-building. Fans sometimes learn these languages, contributing to their popularity and longevity.
