aUI () is a philosophical and ideographic a priori language created in the 1950s by W. John Weilgart, Ph.D. (March 9, 1913 â January 26, 1981; born Johann Wolfgang Weixlgärtner, and also known as John W. Weilgart), a philosopher and psychoanalyst originally from Vienna, Austria. He described it as "the Language of Space", connoting universal communication, and published the fourth edition of the textbook in 1979; a philosophic description of each semantic element of the language was published in 1975.
In his psychotherapy work, Weilgart sometimes used client-created aUI formulations to reveal possible subconscious associations to problematic concepts. aUI can also be considered an experiment in applied cognitive lexical semantics, and Weilgart originally envisioned it serving as an international language for "Peace through Understanding".
aUI has 31 morpheme-phonemes each with an associated meaning. That is, each morpheme corresponds to exactly one phoneme and exactly one sememe.
Additionally, nasal vowels used for numerals are transcribed with carets:
aUI is currently included in the unofficial ConScript Unicode Registry (CSUR), which assigns code points in the Private Use Area. aUI code points are mapped to the range U+E270 to U+E28F.
The eight âÂÂAuxâ variant fonts of Kurinto (Kurinto Text Aux, Book Aux, Sans Aux, etc.) support aUI.
