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 aUI, Ro, Solresol, Mirad, Klingon, Ithkuil, Na'vi, and High Valyrian. By contrast, a posteriori languages are ones whose vocabulary is based on existing languages, either as a variation of one language or as a mixture of various languages.
