aUI

aUI is a philosophical a priori language based on a set of (31) proposed universal semantic primitives, each designated with a simple ideograph, from which words from any culture can be created. Mini-definitions of a word's essential meaning, analogous to chemical formulas, are composed from these elements of meaning. aUI for the first time overcomes the arbitrary nature of existing languages and incorporates an inherently meaningful relationship between Word, Meaning, and Reality, between Sound, Symbol, and Meaning. [W. John Weilgart, Ph.D.]

Eaiea

Eaiea uses groups of notes to form words. Unlike Solresol, this language uses all twelve notes of the musical chromatic scale. [Bruce Koestner]

Ebubo

Ebubo is easy to learn because it is based on common stereotypes of modern human cultures. [Andrew Nowicki]

Eurún

It is simple and easy to learn but with a philosophical touch. [Arne Duering]

Ithkuil

Ithkuil combines an a priori philosophical language with a logical language, using a lexicon of 3600 semantic roots built on a complex, matrix-like grammar designed to achieve maximal communication of cognitive intent and meaning in a highly efficient manner. What Robert Heinlein proposed for morpho-phonology (via "Speedtalk"), Ithkuil delivers for morphology, lexico-morphology, and lexico-semantics as well. There are two parts of speech, formatives and adjuncts, with the former inflecting for 22 morphological categories. The Ithkuil script utilizes a unique "morpho-phonemic" principle to likewise "compress" the written word. The website contains numerous MP3 sound files so visitors can hear Ithkuil pronunciation. [John Quijada]

The language is an incredibly easy language to learn and is intended for use as an international auxiliary lang. [M. Martin]

Leibniz's Characteristica Universalis

Leibniz wrote, "If one could find the characters or symbols to express all our thoughts as cleanly and exactly as arithmetics expresses numbers, or as analytic geometry expresses lines, one could do the same as one can do with arithmetics and geometry, as much as they are subject to reasoning. This is because all investigations that depend on reasoning would take place through the transposition of these characters, and by a kind of calculus." [G.W. Leibniz]

Mänti

Mänti (the name refers to a type of tree) is intended to have a philosophical lexicon embodying relationships between concepts: ema, "mother", creates ela, "life"; päike, "sun", creates päive, "day". [Daniel Tammet]

Microlang 1.0

Sketch of an interspecies pidgin. [James]

Oz

Like Ro, Oz is an a priori philosophical language, with a vocabulary derived not from natural languages but from a classification structure. The vocabulary was to be based on Roget's Thesaurus, but does not seem to have been worked out in its entirety. See Roxhai for an independent attempt at this type of language design. [Charles Milton Elam]

Perio

phonetic picture-writing

The combination of sound and picture: the ideograms are formed by specially designed (few and simple) letters, so that each ideogram can be read phonetically -it's a picture writing and also a true phonetic writing! Also the grammar is basically "optical". Result: a man can speak pictures! [Leonhard Heinzmann]

Ro

Like Solresol, Ro is a pasigraphy (an a priori philosophical language), with a vocabulary derived not from natural languages but from a classification structure. You can roughly guess the sense of a word by recognizing its initial letters; for instance, in Ro, bo- is the category of "sense-affecting matter", and color words (falling under this category) begin with bofo-: bofoc means "red", bofod means "orange" and bofof means "yellow". Unfortunately, if you make a typo in Ro, you've probably just spelled another word, and your spell checker is not going to catch the mistake... [Rev. and Mrs. Edward Powell Foster]

Roxhai

Roxhai is a philosophical language, with its vocabulary automatically structured, as with Ro. For instance: r'o means "sentiment and moral power"; ro'yo, "religious affection"; roc'o, "supernatural being or region"; roca'yo, "Christian supernatural being or region"; and rocac'o, "God". The core vocabulary of Roxhai is based on nouns, with verbs, adjectives and adverbs derived from these. Roxhai was inspired by Solresol, Ro and Esperanto, and is still being refined.
