Fictional languages are languages that have been created for use in fictional works, such as books, movies, and video games. These languages often serve to enhance the world-building of a story, providing depth and authenticity to the cultures and characters within it. Notable examples include Klingon from Star Trek and Dothraki from Game of Thrones. These languages can vary in complexity, from simple phrases to fully developed grammatical systems. They often reflect the unique characteristics of the fictional societies they belong to, making them an intriguing aspect of storytelling and a fascinating subject for linguists and fans alike.
