Artistic language
An artistic language or "artlang" is a constructed language whose primary purpose is to satisfy its maker's creative impulses and, possibly, evoke an emotional response in those who use it. There are no limitations on the form of an artlang; it may be simple or complex, naturalistic or engineered, a priori or a posteriori. The only limitation is that the creative purpose not be subordinated to any practical function (such as creating a language for international communication) or philosophical or experimental purpose (such as creating a maximally simple language, or proving that one can create a language with some specific characteristic).
