A priori (languages)

:"This is the article about constructed languages. For other uses of the term "a priori", see 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 those of fictional Middle-earth. 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 (e.g., Interlingua).

Some "a priori" languages are designed to be international auxiliary languages that remove what could be considered an unfair learning advantage for native speakers of a source language that would otherwise exist for "a posteriori" languages. Some "a priori" languages try to categorize their vocabulary, either to express an underlying philosophy or to make it easier to recognize new vocabulary. These are also known as philosophical or taxonomic languages.
