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, linguistic experimentation, or as part of fictional worlds, such as those found in literature and film. Some well-known examples of conlangs 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.
