Category:A priori

An a priori language is any constructed language whose vocabulary is not based on existing languages, unlike a posteriori constructed languages. Examples of a priori languages include Ro, Solresol, Mirad, Klingon, and Na'vi. By contrast, a posteriori languages are ones whose vocabulary is based on existing languages, either as a variation of one language (e.g., Latino sine flexione) or as a mixture of various languages.
