conlang

1. (linguistics, colloquial) Alternative form of constructed language (“a human language consciously devised by an individual or a small group, as opposed to having naturally evolved as a natural language”)Examples: "The Klingon language is a conlang created for use in the Star Trek franchise."; "You might be familiar with more a priori conlangs than you think: The Klingon language from the television series "Star Trek," the Na’vi language from the movie "Avatar," and the Dothraki language from the television series "Game of Thrones" are all examples of a priori languages. […] Others both inside and outside the academic community feel that conlanging veers too easily into the realm of cultural exploitation (viewers of “Game of Thrones” will remember how the portrayal of the Dothraki race on the show, including the conlang the Dothraki people speak, seemed to many like a portrayal of Native Americans as “barbaric” and “exotic”)."Synonyms: clong, cloŋalt-ofalternativecolloquial
