A "conlang," short for constructed language, is a language that has been artificially created rather than having developed naturally over time. Conlangs are often designed for specific purposes, such as for use in literature, film, or as a means of communication among a particular group. Examples include Klingon from the Star Trek franchise and Dothraki from Game of Thrones. Conlangs can vary widely in complexity, from simple codes to fully developed languages with grammar and vocabulary. Some conlangs, like Esperanto, aim to facilitate international communication, while others, like Quenya from The Lord of the Rings, serve artistic or fictional purposes.
