UNI - UNIVERSAL AUXILIARY LANGUAGE
UNI is a simple international artificial language. It's much easier to learn and speak than any language you know. If you speak any Romance language you will understand roughly 70% of this dialogue — this is an approximate estimate and may vary by individual. Words used in the dialogue go beyond the current reference vocabulary; the vocabulary section is still being expanded and will be more complete in future versions.
There are only 21 letters in full version and 15 letters in simplified (whisper) version where voiced consonants are substituted with their voiceless equivalents.
UNI is a UNICASE language — meaning all letters have a single shared form regardless of size (no separate uppercase/lowercase shapes). Their visual form mirrors capital English alphabet letters. There are no small or lowercase letters for simplicity. Since there are yet no keyboards making capital letters small without changing their visual forms, we'll just use ALL CAPS for now.
English
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
UNI (5 Vowels and 16 Consonants)
A B — D E F G — I J K L M N O P — R S T U V — X — Z
So, as you noticed while reading the dialogue, C, H, Q, W and Y don’t exist in UNI. Not only are they not necessary, but they actually make learning to read more difficult and introduce a lot of confusion.
UNI whisper version goes even further (only 5 vowels and 10 consonants)
A — — — E F — — I — K L M N O P — R S T U — — X — —
(— means the corresponding letter doesn't exist)
UNI has a phonetic spelling system, so every letter is pronounced the same way as it's written, no matter where it appears in a word.
Vowels:
A as in English father, rather, Spanish madre, padre, Portuguese casa, barco
E as in English met, pet, Spanish sempre, cerdo, Portuguese leite, gente
I as in English machine, marine, Spanish ir, sentir, Portuguese isso, bicho
O as in English for, sport, Spanish monte, tonto, Portuguese sorte ponte
U as in English rule, bull, Spanish turno, super, Portuguese puro, duro
Consonants:
B as in big, back
D as in dig, duck
F as in find, fork
G as in god, game
J as in beige, seizure
K as in cat, cry
L as in long, leg
M as in many, men
N as in no, neck
P as in park, place
R as in rent, rock
S as in send, step
T as in train, tune
V as in very, vampire
X as in shark, shop
Z as in zombie, zero
Phonetic Difficulty of some languages
Difficulty is estimated for the average person on Earth (i.e., how common the sounds are across the world's languages). Rankings are approximate and will vary by native language. Scale: 1 = easiest, 10 = hardest.
| Language | Difficulty | Main Challenges |
| UNI | 1 | 21 letters, one sound per letter, no silent letters, no exceptions — designed to be the easiest |
| Esperanto | 1 | Extremely regular and simple |
| Latin | 2 | Clear vowels, very predictable |
| Spanish | 3 | Average European system |
| Italian | 3 | Clear and regular |
| Romanian | 4 | Slightly more complex than Spanish/Italian |
| Portuguese | 5 | Nasal vowels |
| German | 7 | Front rounded vowels, /ç/, /x/, uvular R |
| Greek | 7 | /θ/ and /ð/ |
| French | 8 | Nasal vowels + front rounded vowels + uvular R |
| English | 8 | /θ ð/, /ɹ/, many vowel contrasts, clusters |
| Arabic | 9 | Pharyngeals, emphatics, complex consonants |
| Russian | 9 | Extensive soft vs hard (palatalization) |
| Hindi | 9 | Aspirated stops + full retroflex series |
| Chinese (Mandarin) | 10 | Four tones + retroflexes + aspiration contrast |
Experimental: Even further Simplified (whisper) version would change replaceable voiced consonants to voiceless ones:
B→P, D→T, G→K, J→X, V→F, Z→S
B - P (B as in Barbara and P as in Peter)
D - T (D as in down and T as in top)
G - K (G as in green and K as in kind)
J - X (J as in measure and X as in short)
V - F (V as in very and F as in fine)
Z - S (Z as in zero and S as in smart)
Voiced letters wouldn’t change because they don’t have voiceless equivalents:
L - L (as in later)
M - M (as in meter)
N - N (as in normal)
R - R (as in robot)
KOZA BAZIKU → KOSA BASIKU
PORTUGEZA → PORTUKESA
VIDA NOVU → FITA NOFU
All Present Tense / Infinitive verbs always end in AR. The last syllable stressed in pronunciation.
Example: I pronounce - MI PRONUNSIAR
All Past Tense verbs always add O to the Present Tense / Infinitive. The last syllable is stressed in pronunciation.
Example: think - thought: PENSAR - PENSARO
In full, formal form, we add O to the infinitive form.
In simplified, informal form, the Present / Infinitive ending AR can be omitted and the verb reduced to PENSO with the last syllable stressed in pronunciation.
All Future Tense verbs always add E to the Present Tense / Infinitive. The last syllable stressed in pronunciation.
Example: I will think: MI PENSARE
In full, formal form, we add E to the Present / Infinitive form PENSAR. The last syllable is stressed in pronunciation.
All Conditionals always add BE to the Future Tense or EBE to Present Tense / Infinitive in full, formal form. The penultimate syllable stressed in pronunciation.
Example: I would think - MI PENSAREBE
In simplified, informal form, we can remove the Present / Infinitive ending AR and add EBE, so it becomes PENSEBE. The last but one syllable is stressed in pronunciation in that case.
All Continuous forms always end in ANDU.
Example: I am thinking - MI PENSARANDU
In full, formal form we add ANDU to the infinitive form PENSAR. The last but one syllable is stressed in pronunciation.
In simplified, informal form, we can remove the Present / Infinitive ending AR and add ANDU, so it becomes PENSANDU.
Most Nouns end in A.
Example: AMORA - love. Diminutive - AMORITA, AMORSITA.
Adjectives do not change gender.
All Active Adjectives are formed by changing the last vowel to U.
Example: Lovely - AMORU (noun describer)
AMORA becomes AMORU.
All Passive Adjectives are formed by adding suffix DU to nouns or active adjectives.
Example: Lovable - AMORADU, beloved - AMORUDU.
All Active Adverbs are formed by adding suffix RU to nouns or adjectives.
Example: Lovely - AMORARU
lovingly - AMORANDURU (verb describer).
All Passive Adverbs are formed by adding suffix DU to active adverbs.
Example: Loved - AMORARUDU, loved one - AMORURUDU
*Adverbs are not obligatory. Adjectives can be used instead. Quickly-quick.
Example: All active adverbs AMORARU / AMORURU - can just be active adjectives - AMORU and all passive adverbs AMORARUDU / AMORURUDU - can just be passive adjectives - AMORADU / AMORUDU in informal speech if it doesn’t introduce any crucial semantic ambiguity.
Active Gerund - AMORANDU - loving, lovingly, lover (active continuous verb).
Passive Gerund - AMORUNDU - being loved, the beloved one - (passive continuous verb).
*A lovely/loving mother - AMORARU / AMORANDU MAMA.
A loved mother - AMORADU / AMORUDU MAMA.
Active continuous verbs (gerunds) end in -ANDU. Articles are optional in UNI, so AMORANDU MAMA can mean "a loving mother" or "the loving mother" depending on context. Add an article (UNA / LA) if you need to distinguish "a loving mother" from "loving a mother".
Passive continuous verbs (gerunds) end in -UNDU. Being loved (by a) mother - AMORUNDU (POR) MAMA.
*Noun-to-verb conversions are possible. BONA - good thing. BONAR - to do well, to improve.

Grammar Difficulty Ranking
(Easiest → Hardest) — Rankings are approximate and will vary by native language. Scale: 1 = easiest, 10 = hardest.
| Language | Difficulty | Why |
| UNI | 1 | 3 tenses, no genders, no cases, no moods, zero irregular verbs — designed to be the simplest grammar of all |
| Chinese (Mandarin) | 1 | No conjugation, no genders, no cases, no tenses — only particles and word order |
| Esperanto | 2 | Almost perfectly regular, very few rules, almost no exceptions |
| English | 3 | Very little inflection left, but many irregular verbs and phrasal verbs |
| Spanish | 4 | Rich verb system and subjunctive, but no cases and relatively regular |
| Italian | 4 | Similar to Spanish — complex verbs but clear and consistent |
| Portuguese | 5 | Like Spanish/Italian, plus personal infinitive and more irregularities |
| French | 6 | Complex verbs, many irregulars, and frequent use of subjunctive |
| Romanian | 6 | Romance verbs + residual cases and a neuter gender |
| Greek | 7 | Residual cases, three genders, and a fairly complex verb system |
| German | 7 | Four cases, three genders, strong/weak verbs, and strict word order |
| Hindi | 8 | Gender, postpositions, aspect system, and ergativity |
| Arabic | 9 | Root-and-pattern morphology, dual number, cases (in formal), many irregular verbs |
| Russian | 9 | Six cases, three genders, aspect pairs, and heavy agreement |
| Latin | 10 | Full case system, many tenses and moods, rich morphology, and numerous irregularities |
Key takeaways:
UNI is designed to be the easiest language of all — simpler than Chinese (no tones) and simpler than Esperanto (fewer rules, no cases).
Romance languages become harder mainly because of verbs (especially the subjunctive).
German, Greek, Hindi, Arabic, Russian and Latin are harder because of cases and/or complex morphology.
Languages shown per entry vary by notable gender, phonetic, or usage patterns. Not all languages appear in every entry. Vocabulary is still being expanded — more entries will be added in future versions.
