Teruene is an IAL (International Auxiliary Language) based in part on Esperanto grammar (with Chinese influence), but with words which originate mainly from the world's five most spoken languages: Chinese (Mandarin), English, Spanish, Hindi and Arabic. (Some lists include French before Arabic, but French is sufficiently related to Spanish and English so it doesn't make sense to include it as a major source).

Spanish, English and Hindi represent the three most spoken branches of the Indo-European language family, which itself is spoken natively by about 45% of people worldwide. Chinese is by far the most spoken language in the Sino-Tibetan language family, which is spoken by about 22% of people. Finally, Arabic is the most spoken of the Afroasiatic languages, which in turn are spoken by 6% of the population. Arabic has also had a great influence over other languages, including Swahili and other Bantu languages.

It is an a posteriori agglutinative SVO language, although much more inclined to isolating languages than most agglutinative languages, including Esperanto.


Phonology and orthography

Teruene uses letters of the basic Latin alphabet.

Letter l m n o p r s t u x
IPA Sound l m n (ŋ) o p r (ɾ) s (z) t u (w) ʃ (ʒ)

The names of the vowels are themselves (a, e, i, o, u), while the names of consonant are formed adding an -e (be, ce, se, te, xe, etc.)

The ideal pronunciation for r is the trilled r or the tap, but any similar sound that's distinguishable from the rest of the alphabet is ok.


Words can end in vowels or the following consonants: l, m, n, r, s. Words must not contain consonant clusters of more than two consonants.

If for some speakers it's difficult to pronounce consonants at the end of words, or consonant clusters, they may add a rather neutral and short u/shwa sound, but it should not change the stress of the word.

Allowed consonant clusters:



l r Between


m n s l r
f fl- fr- -nf- -sf- -lf- -rf-
p pl- pr- -mp- -sp- -lp- -rp-
k kl- kr- -nk- -sk- -lk- -rk-
t tr- -nt- -st- -lt- -rt-
b br- -mb- -sb- -lb- -rb-
d dr- -nd- -sd- -ld- -rd-
g gr- -ng- -sg- -lg- -rg-

m -nm- -sm- -lm- -rm-
n -mn- -sn- -ln- -rn-
c -nc- -sc- -lc- -rc-
l -nl- -sl-

Other consonant clusters are not allowed when creating a new root, some of them may appear in word combinations but it is advisable to add a grammatical ending in order to avoid them.


Diphthongs are not phonemic in Teruene (that means that pronouncing them as diphthongs or as separate vowels does not change the meaning). The letters i and u might be pronounced as the nucleus of their own syllables, palatalizing/labializing the previous consonant, or forming a diphthong with another vowel.

For instance something like "ilie" might be pronounced in several ways: /', /', /'i.lʲe/ (all vowels on their own, i as a consonant to e, or i palatalizing l). Similarly, "akue" would be pronounced /'a.ku.e/ or /'a.kʷe/.


Stress falls on the second to last syllable. Well.. it's a bit more complicated than that. Because u and i can be pronounced on their separate syllable or forming a diphthong with another vowel, there are sometimes two ways to select the syllable that takes the stress. In order to make stress regular among speakers regardless of how they pronounce u and i, stress falls on the second to last syllable when accounting for possible diphthongs. Let's see some examples:

  • akue: /'a.ku.e/, /'a.kʷe/
  • kaua: /'ka.u.a/, /'kaw.a/, etc.
  • kiue: in cases such as this, where one could stress either an i or a u because they can make a diphthong together but one of them could also make a diphthong with another one, interpreting that other diphthon with an a, e or o takes precedence, thus /'ki.we/, not */'kiw.e/ or */'kju.e/.

Still, while not respecting stress rules might be confusing, it's not phonemic in Teruene, so mispronouncing stress sometimes should not be a problem.



In the third person there is no distinction of gender, but there is distinction of animate and inanimate things. For thinking beings (animals, including us, imaginary characters, etc) one would use "ta", for plants and other unthinking living things one might use either "ta" or "so", depending on style; for all other things one would use "so".

Plural pronouns are created adding -su, (I decided not to use the plural marker -s because a pronoun ending in -s creates conflict with verbs starting with s-, making for example *"mis suo" (we are) sound like "mi suo" (I am)).


Teruene English
1st person singular mi I
2nd person singular tu you (singular)
3rd person singular animate ta he/she
3rd person singular inanimate so it
1st person plural mimen we
2nd person plural tumen you (plural)
3rd person plural animate tamen they (beings)
3rd person plural inanimate somen they (things)
impersonal pronoun somule one
reflexive pronoun os X-self, own

"Mi" comes from all the European languages where it appears, such as Spanish, English, Italian, etc.

"Tu" comes from Spanish, and it also appears in other European languages such as "du" in german.

"Ta" comes from Chinese "tā".

"So" comes from Spanish "eso".


Normal nouns end in -e in singular form, the plural is formed adding -s. Apart from that, nouns don't change, but they can be combined to form new words.

Proper names

Proper names of people, places, and other things are nouns too, but because they don't usually have adjectival or verbal counterparts, it's possible to adapt names into Teruene without having them end in -e, but important proper names should follow Teruene's phonotactics and orthography as much as possible. For instance, "Argentina, Benesia, Franse, Brasil". Many names might be shortened in order to facilitate certain combinations, "Doice" (Germany) -> "doicuene" (german language).

If one wants to make an adjective out of a proper name, or add a suffix, the ending or suffix can be attached either to the whole word, or just to the last consonant of the name. For instance:

  • Conkuo = China
    • Conka / Conkuoa = Chinese (adj.)
    • Conkuene / Conkuouene = Chinese (language)


Verbs end in -o in infinitive, which is replaced by other endings according to tense or mood. However, infinitive verbs can be used everywhere, representing any tense or mood, while other endings can be used to be more specific about time or mood if context is not clear.

Infinitive -o
Present tense -an
Past tense -el
Future tense -on
Conditional mood -ol
Past conditional mood -em
Imperative/Volitive mood -am

Verbs have five suffixes which are used to create a lot of different verbs from just a few original verbs

  • -ant- specifies a more continuous action or state
    • puo = to say/talk ➜ puanto = to talk/speak/be talking
    • ho = to have ➜ hanto = to own
    • biso = to see ➜ bisanto = to watch/be watching
  • -ek- specifies a more instantaneous action or the beginning of an action
    • rano = to run ➜ raneko = to start running
    • sio = to know ➜ sieko = to learn (to start to know)
    • fo = to do ➜ feko = to do suddenly
    • ho = to have ➜ heko = to get/obtain
    • dormo = to sleep ➜ dormeko = to fall asleep/to start sleeping
  • -end- gives it the meaning of the culmination of the action
    • lo = to go ➜ lendo = to arrive
    • dormo = to sleep ➜ dormendo = to wake up
  • -if- specifies transitive meaning
    • dormeko = to fall sleep ➜ dormekifo = to make someone sleep
    • dormendo = to wake up ➜ dormendifo = to wake someone up
    • eko = to begin ➜ ekifo = to (make something) start
    • folo = to fall ➜ folifo = to drop
  • -os- specifies intransitive or reflexive meaning
    • grabo = to hold/grab ➜ graboso = to hold on to something
    • limpio = to clean ➜ limpioso = to clan oneself
  • -ed- makes the passive voice version of the verb
    • manco = to eat ➜ mancedo = to be eaten
    • fo = to do ➜ fedo = to be done

Verbs and context

It's important to clarify that verbs can have several meanings according to context, and the previously shown suffixes simply pin down the intended meaning. Though usually -end- has a distinct enough meaning that it should not be left out.

Instant vs continuous

Most verbs fall into one of these categories, instant verbs being those that represent a change, and continuous those that represent a state (even if an active one like running).

As shown before, -ek- can be used to express change, while -ant- can be used to express a continuous state. However, when a verb is used without either of these suffixes, it can mean any of the two, allowing context to clarify which one is intended. Example:

  • dormo = to sleep / to fall asleep
    • dormeko = to fall asleep (instantaneous change)
    • dormanto = to sleep (continuous state)
Transitive vs intransitive

Similarly, verbs can be used as transitive, intransitive and reflexive, and context will usually clarify. When context isn't enough, it's possible to use -os-, -if- or the pronoun "os" to specify. This also happens in English with some verbs such as "finish" or "start".

  • endo = to end (something ends or someone ends something)
    • endifo = to end (something)
    • endoso = to end (something ends)
  • folo = to fall / to drop
    • folifo = to drop
    • foloso = to fall

The conditional mood

This mood has two endings: -em for the past and -ol for the rest (usually present). In English the conditional mood is expressed with "would" and with the past tense, while the "past" of the conditional mood is expressed with "would + present perfect" and with past perfect.


  • Se mi siol xenal, mi laborol = If I knew how, I would work


  • Se mi siem xenal, mi laborem = If I had known how, I would have worked

However, most of the time this "past conditional mood" in other languages is used to express something that could or should have been done, but wasn't. In this cases, Teruene can use indicative past tense instead.

  • Mi duel no manco so, tan mi fel = I shouldn't have eaten it, but I did
  • Mi pel rana, tan mi no fel = I could have run, but I didn't


The active participle is the verb root plus the -ant- suffix and an ending according to its function, and the passive participle is created adding -ed- instead:

Form of verb Translation Example sentence Translation
aio to love Mi no kuan aio tu I don't want to love you
aianto to be loving Mi aiantel tu I was loving you
aianta loving (adj) Aianta uome suo bela A loving person is nice
aiantal loving (adv) Aiantal ta, mi sieko Loving him, I learn
aiante lover Ta suel mi te aiante She was my lover
aiedo to be loved Mi aiedo per Lukas I am loved by Luke
aieda loved (adj) Ta suo aieda aite They are a loved parent
aiedal being loved Aiedal, mi suo mas bona Being loved, I'm better
aiede loved one Ta suo mi te aiede He is my loved one

All examples:

  • -ant-:
    • -an: Mi mancantan mafes = I am eating apples
    • -el: Mi manantel mafes = I was eating apples
    • -on: Mi mancanton mafes = I will be eating apples
    • -ol: Mi mancantol mafes = I would be eating apples
    • -em: Mi mancantem mafes = I would have been eating apples
    • -am usually makes no sense with -ant-
  • -ed-: this one is used to create the passive voice, the meaning can vary between present and past depending on the verb and context, for example someone "known" is someone known today, not in the past, on the other hand something "eaten" can be something already eaten (past) or something that is commonly eaten in a place (present). In order to differentiate, one can use words like "hoim" (now).
    • -a: Mafes mancedan = Apples are eaten (or were)
    • -el: Mafes mancedel = Apples were eaten (or had been)
    • -on: Mafes mancedon = Apples will be eaten (or will have been)
    • -ol: Mafes mancedol = Apples would be eaten
    • -em: Mafes mancedem = Apples would have been eaten
    • -am: Mafes mancedam = (Let) apples be eaten!

Note: to show the agent in a passive voice phrase use "per"

  • pane mancedo per uofe = the bread was eaten by the dog

Adjectives and adverbs

Adjectives end in -a. They don't agree in number with nouns (they don't add -s when plural).

Adverbs end in -al and also don't agree in number. Adverbs are optional though, if context is clear and one is not sure whether something should be an adverb or an adjective, they may use an adjective.

Note: remember that even though basically all nouns end in -e, that doesn't mean that all words that end in -e are nouns (for instance "pre" means "before" and is a preposition, not a noun). The same goes for all grammatical endings: -a, -e, -an, -al, -el, -am, etc.



Possession is shown using the te particle, which comes from the Chinese particle "de" and works pretty much like it works for possession ("de" has other uses in Chinese that Teruene's "te" doesn't, though), it's similar to 's in the English language, but also used with pronouns. For example:

  • Mi te aute = My car
  • Ta suo Lukas te penge = She/He is Lucas' friend
  • Dome suo tumen te = The house is yours
  • (Data) uomire, xenule te dome suo ega, suo mi te penge = The man, whose house is big, is my friend.

As with many things in Teruene, te is optional but only when it's preceded by a personal pronoun and context is clear, so one may say "mi penge" (my friend) but not "Lukas penge"*.


Yes/No questions (or questions that give you a definite amount of answers) are created adding the particle ma at the end of the sentence.

  • Tu suo bona = You are good
  • Tu suo bona ma? = Are you good?

Ma can also be used in negative sentences.

  • Tu no suo aitire ma? = You're not a father, are you?

Questions that give you the possible answer usually use the "xor" connector which is basically an "exclusive or" from binary logic (one can use regular "or" instead if one wants to). Examples:

  • Tu kuo kafe xor cate ma? = Do you want coffee, or tea?

In that sentence it is explicitly stated that you can choose either coffee or tea, but not both. Possible answers:

  • (Ia,) kafe. = (Yes,) coffee.
  • (Ia,) cate. = (Yes,) tea.
  • Nula, xiexe. = None, thanks.

Instead, if the speaker wants to give the option of choosing more than one thing, the speaker shall use "or" which is an "inclusive or". For instance:

  • Tu kuo late, sukre or otre en tu te kafe ma? = Do you want milk, sugar or something else in your coffee?
    • Ia, late. = Yes. milk.
    • No, nule. = No, nothing.
    • Ia, (data) dos = Yes, both.

Other questions are made with xen- correlatives, unlike many languages but like Chinese, the order of the sentence does not change (although it is allowed) when asking questions, the xen- word​ is in the place where the answer will be. For example:

  • Tu manco xene? = What are you eating? (You eat what?)
  • Tu suo xenule te aitise? = Whose mother are you? (You are whose mother?)

Word order

Basic word order

Teruene follows the order SVO, but it is also allowed to use OSV (Yoda's order) and VSO. These three orders are allowed because out of the six possible orders one can only choose three and still be able to differentiate subject from object. The one-phrase rule is "the nearer to the left of the verb, is the subject", in SVO and OSV the subject is already to the left of the verb, and in VSO the subject is closer to the left of the verb than the object.

SVO was chosen because it's the most widespread order in the world, which includes English, Spanish and Chinese, the three most spoken languages. It's also useful to have the verb separating subject from object, that allows free order for adjectives.

Apart from order, there is nothing differentiating subject from object, so even pronouns stay the same when they are the object of the sentence:

  • Mi aio tu = I love you
  • Ta aio ta = She/He loves him/her
  • Mimen bisel tamen = We saw them
Adjectives and other modifiers

Adjectives are usually placed before the noun they modify, but if it doesn't create misunderstanding, it is allowed to put them after the noun. When there are two adjectives for one noun, they can be placed together before or after the noun, they can be separated by the noun, by the word for and: "he" or by nothing at all.

  • Bela fasta womise / Womise bela fasta / Bela womise fasta / Bela he fasta womise / Womise bela he fasta = The/a beautiful, fast woman

In general modifiers are written before what they modify.


There is no specific definite (the) or indefinite article (a, an) but the number "uan" (one) can be used if necessary as singular indefinite article, for example there are words which can be either countable or uncountable, adding "uan" states that it is being used as countable:

  • Mi manco mafe = I eat (the) apple (maybe one, maybe a slices, maybe mashed)
  • Mi manco uan mafe = I eat an apple
  • Mi manco mafes = I eat (the) apples

Instead there are words that can't be either countable or uncountable, in those cases "uan" should be avoided:

  • Mi suo uome = I am a/the person

The definite article does not exist because its usage would vary depending on the speaker's mother tongue, it doesn't exist in very important languages such as Chinese and Russian, so for the sake of simplicity Teruene doesn't have it either.


0 1 2 3 4 5 6 7 8 9 10 100 1000
nul uan dos san ion kuin lou ci co nau ten pai mil

Numbers are combined just like in Chinese:

  • 10: ten
  • 20: dosten
  • 30: santen
  • 400: ionpai
  • 800: copai
  • 9 000: nau mil
  • 323 456: sanpai dosten san mil ionpai kuinten lou

After 999 999 there are words created in a similar way to "million", "billion", "trillion" but more regularly: number + ilie. Teruene follows the same scale English does, each new word adds 3 zeros. Unlike English, the word "uan" can be omitted just like it is done for "ten", "pai" and "mil".

  • pai = one hundred
  • mil = one thousand
  • (uan) uanilie = one million
  • dos uanilies = two million
  • ci dosilies = seven billion

It's also allowed to simply read the numbers, like Chinese speakers do for years and phone numbers. This is only when context allows it. For instance:

  • 1998 = uan nau nau co
  • 2000 = dos nul nul nul
  • 233445 = dos san san ion ion kuin

Ordinal numbers are created adding -a like adjectives. Other endings give other useful meanings:

  • uana = first
  • pai dosten coa = one hundred twenty eighth
  • uanal = firstly / in the first place
  • dosogal = in pair/s
  • tenogal = in groups of ten
  • uanilia = one millionth

The reflexive pronoun

Teruene has the reflexive pronoun "os" which is used as such for all other grammatical persons. These are its uses:

  • To make the sentence reflexive for any subject (although it's also possible to use the corresponding pronoun to make it reflexive, for example "mi limpian mi" or "uome mancifan ta"):
    • Mi limpio os = I wash/bath myself
    • Tu mancifo os = You feed yourself
    • Miaue limpian os = The cat cleans itself
  • To specify or emphasize who is the owner of something:
    • Ta bisel (ta te) os te dome = He saw his own house
    • Mi aio (mi te) os te ermise = I love my own sister
  • As the suffix -os- that makes verbs intransitive/reflexive (which is presented above).
  • As a root for word building:
    • osaxe = property


  • Comparative:
    • Ta suo mas bona ke tu = He is better than you
    • Ta suo kimas tala ke tu = He is less tall than you
    • Tu suo mas teliga ke mi suo kiteliga = You are more intelligent than I am dumb
  • Superlative:
    • Ta suo mos bona inter tutules/fro Argentine/de data oge = She is the best one among everyone/from Argentina/of that group
    • Ta suo kimos tala = She is the least tall
  • Equals: Ta suo (datal) bela xenal tu = She is beautiful like you
    • Or: Ta suo bela mesmal tu (suo) = She is beautiful same as you

Subordinate sentences

Subordinate sentences use either xen- correlatvies, or if no xen- correlative works, they use the particle ke:

  • The xen- correlative has to respect word order. When possible, it's usually at the beginning, but when it's the object of the word, one has to be careful.
    • Mi no sio(,) xener ta suo = I don't know where he is
    • Mi tafahan kos xene ta fel date = I understand why he did that
    • Ta suo uome xenule te dome suo kunara = She is the person whose house is red
    • Mi bisel aute xene tu maiel = I saw the car you bought
      • Also: Mi bisel aute, tu maiel xene
  • To connect sentences that can't be connected by a xen- word, the particle "ke" is used
    • Mi sio ke ta suo en os te dome = I know he's in his own house
    • Mi tafaho ke date no suo ipla = I understand that's not possible
  • To connect sentences when the subordinate sentence represents a "ma" question (in English one would use "if" or "whether"), the particle "ma" is used
    • Mi no siel ma ta suel en os te dome = I didn't know whether she was in her house
    • Mi kuesto ma ta puo Teruene = I ask whether she speaks Teruene


Passing from one word type to another

Changing the ending of a word can change its meaning from verb to noun, noun to adjective/adverb, and so on. Let's look what usually happens to the meaning:

  • Adj to verb: the verb usually becomes the transitive verb "to make something Xadj"
    • gara = warm ➜ garo = to heat
  • Verb to adj: adjective for things that are used or necessary to do or related to the action of the verb
    • manco = to eat ➜ manca = for eating/related to eating
  • Verb to noun: this noun usually is the name of the action of the verb, but can also be the process of the verb:
    • manco = to eat ➜ mance = a meal
    • dormo = to sleep ➜ dorme = sleep (noun)
  • Noun to verb: this verb is usually the action that is done with the noun:
    • martile = hammer ➜ martilo = to (use a) hammer
    • aute = car ➜ auto = to drive (a car)
  • Adj to noun: the name of the quality of the adjective most probably
    • bela = beautiful ➜ bele = beauty
    • kibela = ugly ➜ kibele = ugliness
    • fasta = fast ➜ faste = velocity
    • ega = big ➜ ege = size
    • tala = tall ➜ tale = height
  • Noun to adj: usually "related to noun" or "for noun"
    • cate = tea ➜ cata = for tea
      • cata peie = a cup for tea
    • miaue = cat ➜ miaua = for cats

One syllable verbs

All verbs are regular in Teruene, just like in Esperanto. What that means for Esperanto is that every conjugated verb contains at least two syllables, such as "esti, pensas, diris, venu", etc. because every root contains at least one vowel, and every verb ending contains another one, so no one syllable verbs exist. In Teruene, I decided to have a limited amount of one syllable verbs (12 more or less), which are the most commonly used, their roots contain either no vowel, u, or i (ex. su-, h-, si-, etc.). This way speech can be a bit faster.

The verbs are:

  • suo = to be
  • ho = to have
  • puo = to say
  • do = to give
  • sio = to know
  • fo = to do/make
  • kuo = to want
  • lo = to go
  • xo = to like
  • nio = to need
  • po = can / be able to
  • duo = must / should / to have to

When using these verbs for word combination, it will usually be better to use the full infinitive (-o) or the noun (-e) rather than the bare root:

  • nie + rume (need + room) = nierume (room for needs / bathroom).

Also when using the root in other ways, such as using the noun derived from the verb, it's technically possible to just add the -e ending to the root (nio -> nie = to need -> a need), but sometimes it might be necessary to leave the -o ending and add -e after it (do -> doe).

Having these short verbs will surely create some ambiguities, "holo" means "to come", formed with ho- + l-, but maybe at some point there will be an independent word "holo" whose root is hol-, and has a different meaning, that's ok, and though it should be avoided, it usually makes for good jokes.


Correlatives are special words which consist of certain beginnings and endings and are ordered in a table.

"kos -e" and "-a leie" are in the table to explain how they are formed and used because they are common correlatives, but they are not technically their own correlatives, but derived from other correlatives. This system can be used to create new ones too.

The specific words for some of the horizontal meanings are:

  • ime = moment (this is also a suffix)
  • ere = place (this is also a suffix)
  • kose = reason
  • ale = way
  • une = quantity/amount
  • ule = individual (used like "person", "dude" or "guy")
  • leie = type/kind/class

Examples of correlatives in use

  • -a
    • Tu lego xena kitabe? = Which book are you reading?
    • Data dome suan mi te = That house is mine
    • Tu legel hoa kitabe ma? = Have you read this book?

The useful word "ke"

"Ke" has many uses, most of them are designed to make our lives easier, sometimes by replacing longer or more specific words when they are not really necessary.

"Ke" for comparisons

First, "ke" is used as the word "than" for comparisons:

  • Ta suo mas bona ke tu = He is better than you
  • Ta suo kimas tala ke tu = He is less tall than you

"Ke" in subordinate sentences

As seen previously, "ke" can be used to connect sentences when they can't be connected with xen- correlatives:

  • Mi sio ke ta suo en os te dome = I know he's in his own house
  • Mi tafaho ke date no suo ipla = I understand that's not possible
  • Mi no siel ke ta suel en os te dome = I didn't know that she was in her house

"Ke" replacing xen- words

When context allows and xen- words are either long, obvious, or simply make a sentence ugly, they can be replaced with "ke":

  • Ta suo uome ke dormo hoer (instead of "xenule") = He is the person who sleeps here
  • Data uomire, ke te dome suo ega, suo mi te penge (instead of "xenule") = That man, whose house is big, is my friend
  • Tu suo ke te aitise? (instead of "xenule") = Whose mother are you?
  • Tu lego ke kitabe? (instead of "xeni") = What book are you reading?
  • Date suo ke? (instead of "xene") = What is that?
  • Mi te aute suo ke? (instead of "xener") = Where is my car?
  • Kos ke tumen fo date? (instead of "xene") = Why did you do that?

Days, months and years

The names of the days is created in a similar way to Chinese and Portuguese, with numbers. Months too. Monday is considered the first day of the week. The system is really simple: number + ote. There are two words for "day" in Teruene, one with the meaning of "rotation" for the 24 h day (ote), and one which represents the hours of light of one day (solime), which means "sun time".

Monday Tuesday Wednesday Thursday Friday Saturday Sunday
Uanote Dosote Sanote Ionote Kuinote Louote Ciote

Months are created the same way but with the word "lune" which means both "moon" and "month". And weeks are lun+ab+e, meaning "a fraction of moon".

January February March April May June
Uanlune Doslune Sanlune Ionlune Kuinlune Loulune
July August September October November December
Cilune Colune Naulune Tenlune Tenuanlune Tendoslune

The word for year is "iare". The order of dates is dd/mm/yyyy, let's see some examples:

  • Mi biteko ces sana hore he dosabe dosarote tenuana (rote) de ionlune uan nau nau co
    • I was born at 3:30 Tuesday the 20th of April 1998
  • Mi dormel dur lunabe = I slept during one week

Common phrases

  • Haie = Hi/Hello
  • Bona rote = Good day (at any time)
  • Bona solime = Good day (during daitime)
  • Bona kisolime = Good night
  • Bona morne = Good morning
  • Bona kimorne = Good afternoon
  • Til sun = See you soon
  • Til posote = See you tomorrow

  • Bona mance! = Bon appetit!
  • Bona boie! = Bon voyage! (Good trip!)
  • Helse! = Health!


Important note: when prepositions are used alone (they are not working as prepositions but rather as adverbs), it is recommended to place them at the end of the sentence or in the place where they create the least misunderstandings, or a comma is placed after them to represent a silence.

To “to” direction

Ki- and no-

The word no can be used in a similar way to ki- but they are not the same, the first one is the negation of the meaning, while the second one is the opposite meaning. Sometimes both arrive at the same meaning, in those cases ki should be used, but no may be used when ki does not create the correct meaning or doesn't make sense at all.

There are words that could have been created through ki, but two separate roots have been chosen because either a shorter word was needed (such as for prepositions), a root that started in a vowel was needed (for suffixes such as eg and it), or the two words should be different for better understanding (such as pre and pos).

Family words

There are four main family words:

  • aite = parent
  • ihe = offspring (son/daughter)
  • erme = sibling
  • espe = spouse

With those, the -is-/-ir-/-ip- suffixes for gender, and the -it-/-eg- suffixes for age, we can create most of the family words that a culture may need. For example:

  • aitaite = grandparent
  • aitiraitise = the mother of my father
  • ermihe = nephew/niece
  • aiterme = uncle/aunt
  • aitermespe = uncle's/aunt's spouse
  • aitermihe = cousin
  • ihihe = grandson/granddaughter
  • ermisite = younger sister
  • ermirege = older brother
  • ermespire = a sibling's husband
  • and many many more...

Person, human, man and woman

The word for human, man and woman is "uome" which may take a suffix to specify gender. However, even though some languages, like Chinese, have only one word for person/human, I decided to have a separate word for person, since humans are a species, while person is more like an intelligent being. Think about it, would you rather call an Artificial Intelligence which is as smart and concious as us a human or a person? Would you rather call an intelligent alien a human or a person? Also the word "person" is used for other meanings, such as "juridical person". So, the word for person is "persone".

IUPAC nomenclature

Alkanes (alkanes), alkenes (alkenes) and alcynes (alkines) use Teruene numbers as prefixes.

Number of carbons 1 2 3 4 5 6 7 8 9 10 11 12 20
Prefix uan dos san ion kuin lou ci co nau ten tenuan tendos dosten


  • Uanalkane = methane
  • Dosalkene = ethene
  • Tenuanalkine = undecyne

This is just an example. Similar prefixes and suffixes can be created from Teruene's own words to create a scientific vocabulary much more comprehensible to common people, not just scientists who studied for years.

Example text

The North Wind and the Sun

The North Wind and the Sun were disputing which was the stronger, when a traveler came along wrapped in a warm cloak. They agreed that the one who first succeeded in making the traveler take his cloak off should be considered stronger than the other. Then the North Wind blew as hard as he could, but the more he blew the more closely did the traveler fold his cloak around him; and at last the North Wind gave up the attempt. Then the Sun shined out warmly, and immediately the traveler took off his cloak. And so the North Wind was obliged to confess that the Sun was the stronger of the two.
