The "Language of Space"

By T. Peter Park (2000)

Edited, updated, and revised by Andrea Weilgart Patten (2025)

Andrea Weilgart Patten is the daughter of W. John Weilgart, creator of aUI, the Language of Space. She, along with her sister, grew up helping their father in his life-long work on aUI. Says Andrea: "Beginning in about 1968 until my father's retirement ten years later, we learned aUI along with his college students at weekly classes, at first in our home, then at an evening psychology of communication seminar at Luther College. We would participate as other students, often being called to write aUI formulations on the blackboard or read aloud from the textbook. I also typed out many of his manuscripts written in shorthand. I greatly appreciate this opportunity to correct some common inaccuracies and misunderstandings in Peter Park's original article. Though it is a long time ago, the article still shows up on some searches for aUI and is cited in other conlang sources. I have been steadily working along with a linguistic consultant to develop an authoritative source and teaching information on aUI at our website: https://aUIlanguage.space."


Probably the most bizarre artificial "universal" language of recent times is aUI (pronounced "aha-OO-ee"), the "Language of Space." aUI, meaning "space—mind/spirit—sound" or "space-language," and described as the "Pentecostal Logos of Love and Peace," was launched on Planet Earth in the 1960s by John W. Weilgart, PhD, an Austrian-born psychology professor and psychotherapist[1]. aUI, according to Weilgart, is a logical and rational language, and learning aUI can in some cases help a person become aware of irrational thinking patterns.

I first heard of John W. Weilgart, aUI, and how he allegedly received the language, in a couple of articles on UFOs published in the late 1960s by Brad Steiger, a prolific, rather sensationalistic popular writer on UFOs and other weird, para-scientific, and occult topics. Steiger apparently took Weilgart's story of an extraterrestrial source quite seriously and discussed aUI as a possibly valid, important, and worthwhile revelation from our "space brothers" (Revelation: The Divine Fire, 1973). However, his daughter "understood it to be a childhood vision that he later acted upon in 1952." A few years ago, just out of curiosity, I decided to see for myself what aUI was like, and ordered two of Weilgart's books: aUI: The Language of Space: Pentecostal Logos of Love & Peace, 4th ed. (Decorah, IA: Cosmic Communication Co.,Company, 1962, 1979) and Cosmic Elements of Meaning: Symbols of the Spirit's Life: A Cosmology for Mankind's Survival in the Atomic Age of Space (Decorah, IA: Cosmic Communication Co., 1975).

The aUI language itself strikes me as a rather interesting example of a constructed a priori "oligosynthetic" language, rather in the tradition and spirit of the 17th century pasigraphic efforts of John Wilkins, George Dalgarno, and Gottfried Wilhelm von Leibniz.

The possibility of sound-symbolism as discussed by linguists like Morris Swadesh (The Origin and Diversification of Language, 1971), Otto Jespersen (Language: Its Nature, Development and Origin, 1922), and Edward Sapir (Selected Writings of Edward Sapir in Language, Culture and Personality, ed. David G. Mandelbaum, 1949, 1963) is not part of Weilgart's design because aUI is not based on conventional languages. Rather, aUI represents a totally à priori attempt to create a logical language without dependence on 'natural' languages, except for the set of the most fundamental concepts of human thought and expression that Weilgart posited to be universal. aUI bases its sound symbolism on how these basic concepts are intuitively felt, as well as their placement and articulation in the oral cavity. For instance, a long held, back vowel 'O' /o:/ represents Feeling (O) O, which tends to be a sound expressed when we feel deeply; U /u:/ for Mind/Spirit (U) U is also a mysterious concept placed far back but higher than /o:/. Light (i) i is represented by the short, high, front vowel i /i/ which is the brightest vowel with the highest frequency. The 'b' for Together b is a bilabial stop as the lips are visibly pressed together.

A Short Course in aUI

In aUI, each element of the language consists not only of phonemes but also their meanings (sememes) as fundamental concepts, as well as their symbolic morphemes. Unfortunately, these are not easily reproduced here, but for instance, Space (a) a is represented by a circle (space is all around us) and pronounced as a short /a/; Time (A) A is depicted by an oval (measured in elliptical orbits) and is held longer /a:/, as time lasts. So, there is an inbuilt relationship between sound, symbol, and meaning. Each vowel and each consonant is a basic element signifying one basic concept, and the meaning of every word is built out of these elements. Essentially, this means that every letter stands for one particular basic idea and always stands for that idea. The aUI alphabet and sound-system consists of the short vowels (lower-case) a a, e e, i i, o o, u u, the long vowels (upper-case) A A, E E, I I, U U, O O, Ø q, Y Y, the nasalized vowels (long and short) â 1, ê 2, î 3, û 4, ô 5, Â 6, Ê 7, Î 8, Û 9, Ô 10, Ŷ 0, and the consonants r r, L L, y y, m m, n n, w w, v v, f f, h h, j j, c c, s s, z z, g g, k k, t t, d d, p p, b b.

The short and long vowels, aeiuo a e i u o and AEIUO A E I U O, are pronounced as in Spanish, Italian, and German; lower case y y is pronounced as in yellow; Y Y is pronounced like German ü in Brücke, fünf or French u in lutte, duc or German über, kühl or the French u, û in pur, mur, dur, Vaucluse, s'amuse, sûr; Ŷ 0 is a nasalized version of Y Y; Ø q has the sound of German ö or French eu; c c is like English sh in ship, shoe, fish; j j has the zh sound of s in pleasure, z in azure; x has the sound of German ch in Buch, Nacht, machen, sprach, doch; g g is always "hard" or velar as in English go, get; the b,d,f,h,k,L,m,n,p,r,s,t,v,w,z have their usual English values. The short vowels a a, e e, i i, o o, u u stand respectively for "Space/place (a) a, Movement (e) e, Light (i) i, Life (o) o, Human/person (u) u.

Negation (no, not, non-, un-, anti-), which is expressed by nasal grunts in the "natural intuitive language" posited by linguists Otto Jespersen and Morris Swadesh, and by Esperanto ne, Loglan no, Lojban na, is expressed in aUI instead by y y, the sound of German ü or French u. (However, there is no relation here, these conlangs not being a priori, so it does not really make sense to judge aUI through the prism of other languages, conventional or constructed.) The long vowels A A, E E, I I, U U, O O, Ø q, Y Y respectively "Time (A) A, Matter (E) E, Sound (I) I, Mind/Spirit (U) U, Feeling (O) O, Condition (Ø) q, Negation (Y) Y." The name of the language, aUI, thus, literally means "Space (a) a-Mind (U) U-Sound (I) I," the "mind-sound of space," thus "the language of space."

Of the consonant phonemes, w w signifies "Power, strong, work." The v v represents "Action, do, make, active" and as final -v serves as the aUI verb-ending. The m m stands for "Quality," and -m serves as the aUI adjective ending, corresponding to English -ful, -ish. The n n signifies "Quantity, number, count, many," and final n serves as the optional plural sign. Neither the m m nor the n n bears any of the symbolic associations of the nasals stressed by Swadesh, such as "negation, first- or second-person pronoun, mother, woman," but again, aUI was not based on other existing languages.

The r r means "Positive, Good," while L L signifies "Round." Of the other aUI consonants: f f means "This," h h means "Question, what?", j j stands for "Equality, even, horizontal," c c means "Existence, be, is," s s denotes "Thing," z z designates "Part, divide," g g signifies "Inside, inner," and k k stands for "Above, up, top, high, upper." Finally, t t denotes "Toward, to, direction, tendency," d d means "through, by means of," b b signifies "Together," and p p represents "Before, front, in front, pre-, pro-, proto-."

From y y & Y Y, "negative, opposite, un-, anti-" and Ŷ 0 "zero," we get the derivatives Yr Yr "no!" (Opposite-Positive), Yr- Yr- "mal-, ill-, bad-, dys-" (Opposite-Good), Yc Yc "not, is not" (Not-Is), Yg Yg "out, outside, outer" (Opposite-Inside), Yk Yk "under, below," (Opposite-Above), Ŷn 0n "no, none" (Zero-Quantity), Yn- Yn- "little, micro, mini- " (Opposite-Quantity), and Yv Yv "passive, conceptive" (Opposite-Active).

Big, small, much, many, little, and few are respectively nam nam (Quantity-Space-adj.), Ynam Ynam (Opp.-Quantity-Space-Adj.), nEm nEm (Quantity-Matter-Adj.), nEn nEn (Quantity-Matter-Plural), YnEm YnEm (Opp.-much), and YnEn YnEn (Opp.-many). The color names have what I find a super-logical quality: "white" and "black" are bim bim (Together-Light-Quality) and Ybim Ybim (Opp.-white), but the other colors are simply numbered in spectral order – âim 1im "red" (First-Light-Quality), êim 2im "yellow" (Second-Light-Quality), îim 3im "green" (Third-Light-Quality), ûim 4im "blue" (Fourth-Light-Quality), and ôim 5im "violet" (Fifth-Light-Quality), a name-scheme that presupposes knowledge of the electromagnetic spectrum. They do not have the sort of resonance with natural human languages found, for instance, in Loglan & Lojban blanu "blue," Loglan & Lojban blabi "white," Loglan brona Lojban bunre "brown," or Loglan grisi Lojban grusi "gray." (Again, not related, but there is a lot of similarity with SolResol in terms of how colors and days of the week, for instance, are represented.)

The demonstrative is f f, "this," from which we get fu fu "I, me" (literally This-Person), fnu fnu "we" (literally, This-Many-Persons), fa fa "here" (literally This-Place, from f f + a a "Space"), and Yfa Yfa "there" (literally, Opposite-here"). The demonstratives can also be expressed as fE fE "this" (literally, This-Matter) and pfE pfE "there" (literally, Before-This). The other personal pronouns are bu bu "you" (Together-Person), bnu bnu "you, plural" (Together-Many-Humans), and "he/she" cu cu (pronounced 'shu', literally Existing-Human).

As with personal pronouns, sex and gender terms in aUI all end in Human. Basic biological differences have been used to base sex terms on, but are, by necessity, generalizations since sexual identity is not necessarily based on biological characteristics and there exist genetic variations as well as other health conditions that affect fertility. Therefore, Weilgart's daughter has concluded that differentiating sex and gender is not necessarily where aUI's focus lies, but instead "on our essential common humanity and spirituality: umU umU (Human-Quality-Spirit)."

Still, these terms are possible in aUI (if taken with a bit of humor): LoYtmu LoYtmu for "female" ('egg-Quality-Human', referring to the ovum) and tonvu tonvu for "male" ('seed-Active/Make-Human', referring to active sperm). So, the gendered pronouns are vu vu "he" (Active-Person, male-person), and mu mu "she" (Quality*-Person, female-person). "Father" and "mother" then are respectively Ytvu Ytvu and mYtLu mYtLu, literally "from-male" and "from-female," that is, "originating-active-person" and "originating-quality-person," or "active progenitor" and "vessel progenitor."

*[Note from aUI Webonary: The open vessel shape of m m, Quality, is an ancient symbol for female; further biologically based characteristics are having the Quality of Rounded Life suggesting both the ovum as well as other curvaceous features! https://www.webonary.org/aUI/.*]

Compare aUI "LoYtmu LoYtmu" for female (and "Lomu Lomu" for woman) with Loglan "fumna," Lojban "ninmu," or aUI "nYtvu nYtvu" and "mYtLu mYtLu" for "father, mother" with Loglan "farfu, matma" or Lojban "patfu, mamta": the aUI "mother" contains the m m-sound in common with such human "mother"-words as English "mother, ma, mom, mommy," French "mère," Spanish "madre," German "Mutter," Russian "matj," Hindi "mâtâ," Estonian "ema," Hungarian "anya," Turkish "anne," Arabic "umm," Hebrew "em," Swahili "mama," Zulu "umame," Chinese "mû," Korean "mo," Thai "mää," Vietnamese "me," Tagalog "iná," Tamil "ammaa," Eskimo "anaanak," Lakota "ena," Nahuatl (Aztec) "naan, naantli," Yucatec (Mayan) "nan," Tarascan "naná," Cuna (San Blas) "nan," Mosetene "ñoño," etc., that have so impressed linguists like Otto Jespersen and Morris Swadesh with their strong suggestion of a probable natural psychological sound-symbolism linking the nasals "m m, n n" with "mother, breast, suck," etc.

On the other hand, aUI does strike me as producing something inadvertently "Gemütlich," "homey," and "warm-fuzzy" in its word for "friend," bru bru, "Together-Good-Person," which suggests the purring of a contented cat, as well as English "brother" and German "Bruder"! The same is true for the very similar aUI word for "peace," brU brU, literally "Together-Good-Spirit" or "Together-Positive-Mind." However, "beauty" and "beautiful" are expressed as riO riO, "Good--Light-Feeling (sight)" and riOm riOm, "Good-sight-Quality", i.e. "good-to one's sight" which perhaps do not seem to sound quite as "beautiful" by human natural-language standards as Esperanto "bela," Loglan "bilti," Lojban "melbi", with their echoes of French "belle," Spanish & Italian "bella," and Chinese "mêili." Lojban "melbi nixli," Loglan "bilti nirli," and (despite the awkwardness and sexism of "knabino" with its kn- beginning and derivative feminine ending) Esperanto "bela knabino" seem far more intuitively plausible as "beautiful girl" to me than does aUI "riOm riOm Yn-mu Yn-mu" – or maybe that simply proves that I myself happen to be more accustomed to admiring pretty girls from Earth than from Zeta Reticuli or Epsilon Eridani?

Weilgart's daughter marks the aUI nasalized vowels with carets though he himself had used underlining in his books for the nasal vowels, but underlining is not easily supported on the net. However, the change is really not important, because Weilgart also gave the hieroglyphics (ideographs) in which our "Space Brothers" themselves write aUI and used his Romanized transliteration mainly as a pedagogic aid for beginning learners.
