A "conlang," short for constructed language, is a language that has been artificially created rather than having developed naturally over time. Conlangs can be designed for various purposes, including artistic expression, communication in fictional worlds, or linguistic experimentation. Examples include Esperanto, which aims to facilitate international communication, and Klingon, created for the Star Trek franchise. Conlangs often have their own grammar, vocabulary, and phonetics, making them unique systems of communication. Some conlangs, like Dothraki and High Valyrian, were developed for popular media, while others, like Lojban, focus on logical structure. These languages can foster creativity and community among their speakers.
