An artistic language, or artlang, is a constructed language designed for aesthetic and phonetic pleasure. Constructed languages can be artistic to the extent that artists use it as a source of creativity in art, poetry, calligraphy or as a metaphor to address themes such as cultural diversity and the vulnerability of the individual in a globalizing world. They can also be used to test linguistical theories, such as Linguistic relativity.
Unlike engineered languages or auxiliary languages, artistic languages often have irregular grammar systems, much like natural languages. Many are designed within the context of fictional worlds, such as J. R. R. Tolkien's Middle-earth. Others can represent fictional languages in a world not patently different from the real world, or have no particular fictional background attached.
