World-building languages are constructed languages created for fictional settings, often used in literature, film, and games. These languages enhance the depth of a fictional universe, allowing for richer storytelling and character development. Examples include Klingon from Star Trek and Dothraki from Game of Thrones. These languages often have their own grammar, vocabulary, and pronunciation rules, making them distinct from natural languages. They can reflect the culture and history of the fictional world, providing fans with a more immersive experience. Language creators, or conlangers, often develop detailed linguistic structures to support their worlds.
