Fictional languages are constructed languages created as part of a fictional setting, for example in books, movies and video games. Fictional languages are intended to be the languages of a fictional world and are often designed with the intent of giving more depth and an appearance of plausibility to the fictional worlds with which they are associated, and to have their characters communicate in a fashion which is both alien and dislocated. While most fictional languages are just gibberish, a few are fully functioning and comprehensive languages that can be learned.
