Terwene 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.

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


Terwene uses letters of the basic Latin alphabet.

The stress is always on the syllable before the last one.

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

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

The semivowels w and y can be pronounced labializing/palatalizing the previous consonant, as forming a diphthong with a vowel, or, if that is too difficult, as separate vowels (trying to make them as short as possible and never being stressed).


Words can end in vowels, semivowels, or the following consonants: l, m, n, r, s, x. Words must not contain consonant clusters of more than two consonants (not counting semi-vowels). Each vowel can be assigned one semi-vowel when pronouncing a word, not two, for example "yawa" should be pronounced "ya-wa" not "yaw-a".

If for some speakers it's difficult to pronounce consonants at the end of words, they may add an u sound after it, but it should not change the stress of the word.

Allowed consonant clusters:



l r w y Cross

c cwo cyo amce ance asce alce arce awce ayce
l lwo lyo asle awle ayle
r rwo ryo awre ayre

Other consonant clusters are not allowed when creating a new root, though some of them may appear in word combinations when it's not possible to add an ending in between them.

Allowed diphthongs:

vowel+w w+vowel vowel+y y+vowel
a aw wa ay ya
e ew we ey ye
o ow wo oy yo
i wi
u uy yu

If someone find a diphthong too difficult to pronounce, they may pronounce them as separate vowels (w as u, y as i), as long as they are not stressed.



In the third person there is no distinction of gender, but there is distinction of animate and inanimate things. This can be interpreted in many ways. Usually, one would use "ta" for people (or beings that are considered to have personhood) and "so" for any other thing. More generally "ta" can be used for anything that is capable of communicating, however it can be used for animals, plants or inanimate things for stylistic reasons, such as speaking to or about pets.

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 swa" (we are) sound like "mi swa" (I am)).


Terwene English
1st person singular mi I
2nd person singular tu you (singular)
3rd person singular (human) ta he/she
3rd person singular (not human) so it
1st person plural misu we
2nd person plural tusu you (plural)
3rd person plural (human) tasu they (beings)
3rd person plural (not human) sosu 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 the general form, but unlike many languages, Terwene's general form for nouns is not exactly the singular, instead, it could be said this is the "number neutral" form,which can be interpreted as either plural or singular. The plural is formed can be specified adding -s.

What does that mean? Let's look at some examples:

  • bisile = (the) eye/eyes
    • bisiles = (the) eyes
  • awte = (the) car/cars
    • awtes = (the) cars

When a noun is used with words that clarify an amount, it is not necessary to use the -s ending:

  • One apple: wan mafe = wan mafe
  • Many people: bahi wome = bahi womes

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 Terwene without having them end in -e, but important proper names should follow Terwene's phonotactics and orthography as much as possible. For instances, "Argentina, Benesya, Franse, Brasil". Many names might be shortened in order to facilitate certain combinations, "Doyce" (Germany) -> "doycwene" (german language).


Verbs end in -a in infinitive, which is replaced by other endings according to tense or mood. However, similar to how nouns in basic form can be used, 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 -a
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

  • -ad- gives the verb more duration, if the verb means an instant action, then adding this suffix usually makes it mean the result of that action. Examples:
    • pwa = to say ➜ pwada = to talk/speak
    • ha = to have ➜ hada = to own
    • bisa = to see ➜ bisada = to watch/look at
  • -ek- gives the verb a more instantaneous meaning or the beginning of the action
    • rana = to run ➜ raneka = to start running
    • sia = to know ➜ sieka = to learn (to start to know)
    • fa = to do ➜ feka = to do suddenly
    • ha = to have ➜ heka = to get/obtain
    • dorma = to sleep ➜ dormeka = to fall asleep/to start sleeping
  • -end- gives it the meaning of the culmination of the action
    • la = to go ➜ lenda = to arrive
    • dorma = to sleep ➜ dormenda = to wake up
  • -if- makes the verb transitive if it wasn't, else it makes it "to cause someone do X-action"
    • dormeka = to fall sleep ➜ dormekifa = to make someone sleep
    • dormenda = to wake up ➜ dormendifa = to wake someone up
    • eka = to begin ➜ ekifa = to (make something) start
    • fola = to fall ➜ folifa = to drop
  • -os- is only used on transitive verbs to make them intransitive or reflexive.
    • graba = to hold ➜ grabosa = to hold on to something
    • grabeka = to grab ➜ grabekosa = to grab on to something (to start to be holding on to something)

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.

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 -ad- 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:

  • doma = to sleep / to fall asleep
    • dormeka = to fall asleep
    • dormada = to sleep
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".

  • enda = to end (something ends or someone ends something)
    • endifa = to end (something)
    • endosa = to end (something ends)
  • fola = to fall / to drop
    • folifa = to drop
    • folosa = 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.


  • Si mi siol xeno, mi laborol = If I knew how, I would work


  • Si mi siem xeno, 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, bat wasn't. In this cases, Terwene can use indicative past tense instead.

  • Mi dwel no manca so, tan mi fel = I shouldn't have eaten it, but I did
  • Mi cel 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
aya to love Mi no kyan aya tu I don't want to love you
ayanti loving (adj) Mi swel ayanti tu

Ayanti wome swa beli

I was loving you

A loving person is nice

ayanto loving (adv) Ayanto ta, mi sieka Loving him, I learn
ayante lover Ta swel mi te ayante She was my lover
ayedi loved (adj) Mi swan ayedi per Luke I am loved by Luke
ayedo being loved ayedo, mi swa mas boni Being loved, I'm better
ayede loved one ta swa mi te ayede He is my loved one

All examples:

  • -ant-:
    • -an: Mi swan mancanti mafes = I am eating apples
    • -el: Mi swel mancanti mafes = I was eating apples
    • -on: Mi swon mancanti mafes = I will be eating apples
    • -ol: Mi swol mancanti mafes = I would be eating apples
    • -em: Mi swem mancanti 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).
    • -am: Mafes swan mancedi = Apples are eaten (or were)
    • -el: Mafes swel mancedi = Apples were eaten (or had been)
    • -on: Mafes swon mancedi = Apples will be eaten (or will have been)
    • -ol: Mafes swol mancedi = Apples would be eaten
    • -em: Mafes swem mancedi = Apples would have been eaten
    • -am: Mafes swam mancedi = (Let) apples be eaten!

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

  • pane swa mancedi per wofe = the bread was eaten by the dog

Adjectives and adverbs

Adjectives end in -i or -al. Yes, there are two endings. They don't agree in number with nouns.

There are two endings because -i is a more appropriate ending for most cases, but some roots end in -i or -y and would have been uncomfortable with another -i on top of it, so I decided that the -al ending will be used in those cases.

  • boni = good
  • nayal = young
  • nyal = in need
  • nyedi = necessary
  • lial = strong
  • beli = beautiful
  • kawai = cute

Adverbs end in -o 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), or that "anti" is an adjective (it's a preposition too, the ajdective "antial" means "opposed"). The same goes for all grammatical endings: -a, -e, -an, -o, -i, -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 Terwene's "te" doesn't, though), it's similar to 's in the English language, but also used with pronouns. For example:

  • Mi te awte = My car
  • Ta swa Lukas te penge = She/He is Lucas' friend
  • Dome swa tusu te = The house is yours
  • (Dati) womire, xenule te dome swa egi, swa mi te penge = The man, whose house is big, is my friend.

As with many things in Terwene, 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 swa boni = You are good
  • Tu swa boni ma? = Are you good?

Ma can also be used in negative sentences.

  • Tu no swa aytire 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 kya 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:

  • (Ya,) kafe. = (Yes,) coffee.
  • (Ya,) cate. = (Yes,) tea.
  • Nuli, xyexe. = 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 kya late, sukre or otre en tu te kafe ma? = Do you want milk, sugar or something else in your coffee?
    • Ya, late. = Yes. milk.
    • No, nule. = No, nothing.
    • Ya, ambi = 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 manca xene? = What are you eating? (You eat what?)
  • Tu swa xenule te aytise? = Whose mother are you? (You are whose mother?)

Word order

Basic word order

Terwene 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.

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 aya tu = I love you
  • Ta aya ta = She/He loves him/her
  • Misu bisel tasu = 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.

  • Beli fasti womise / Womise beli fasti / Beli womise fasti / Beli he fasti womise / Womise beli he fasti = 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 "wan" (one) can be used if necessary as indefinite article, for example there are words which can be either countable or uncountable, adding "wan" states that it is being used as countable:

  • Mi manca mafe = I eat (the) apple (maybe one, maybe a slices, maybe mashed, maybe many)
  • Mi manca wan mafe = I eat an apple
  • Mi manca mafes = I eat (the) apples

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

  • Mi swa wome = 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 Terwene doesn't have it either. For example let's look at comparisons. The words for comparative and superlative are "mas" (more) and "mos" (most), and the word for "than" is "ke":

  • Mi swa mas boni ke tu = I'm better than you
  • Mi swa mas tali ke tu = I'm taller than you
  • Ta swa mas beli ke tu = She's more beautiful than you
  • Ta swa mos beli = He is the most beautiful

But there is other way to say the superlative:

  • Ta swa mas beli ke tutules = He is more beautiful than everyone


0 1 2 3 4 5 6 7 8 9 10 100 1000
nul wan dos san kwar kwin low ci co naw ten pay mil

Numbers are combined just like in Chinese:

  • 10: ten
  • 20: dosten
  • 30: santen
  • 400: kwarpay
  • 800: copay
  • 9 000: naw mil
  • 323 456: sanpay dosten san mil kwarpay kwinten low

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

  • pay = one hundred
  • mil = one thousand
  • (wan) wanilye(n) = one million
  • dos wanilye(s) = two million
  • ci dosilye(s) = 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 = wan naw naw co
  • 2000 = dos nul nul nul
  • 233445 = dos san san kwar kwar kwin

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

  • wani = first
  • pay dosten coi = one hundred twenty eighth
  • wanio = firstly / in the first place
  • doso = in pair/s
  • teno = in groups of ten
  • ...

The reflexive pronoun

Terwene has the reflexive pronoun "os" which is used 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 same subject twice in the sentence to make it reflexive, for example "mi limpan mi" or "wome mancifan ta"):
    • Mi limpa os = I wash/bath myself
    • Tu mancifa os = You feed yourself
    • Myawe limpan 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 aya (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
    • morta = to die; morti = dead; morte = death; mortifa = to kill; mortife = an assassination; ➜ osmortifa = to suicide; osmortife = a suicide


  • Comparative:
    • Ta swa mas boni ke tu = He is better than you
    • Ta swa kimas tali ke tu = He is less tall than you
    • Tu swa mas teligi ke mi swa kiteligi = You are more intelligent than I am dumb
  • Superlative:
    • Ta swa mos boni inter tutules/fro Argentine/de data oge = She is the best one among everyone/from Argentina/of that group
    • Ta swa kimos tali = She is the least tall
  • Equals: Ta swa (dato) beli xeno tu = She is beautiful like 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 sia(,) xener ta swa = I don't know where he is
    • Mi tafahan kos xene ta fel date = I understand why he did that
    • Ta swa wome xenule te dome swa kunari = She is the person whose house is red
    • Mi bisel awte xene tu mayel = I saw the car you bought
      • Also: Mi bisel awte, tu mayel xene
  • To connect sentences that can't be connected by a xen- word, the particle "ke" is used
    • Mi sia ke ta swa en os te dome = I know he's in his own house
    • Mi tafaha ke date no swa ipli = 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 swel en os te dome = I didn't know whether she was in her house
    • Mi kwesta ma ta pwada Terwene = I ask whether she speaks Terwene


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"
    • gari = warm ➜ gara = to heat
  • Verb to adj: adjective for things that are used or necessary to do or related to the action of the verb
    • manca = to eat ➜ manci = 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:
    • manca = to eat ➜ mance = a meal
    • dorma = to sleep ➜ dorme = sleep (noun)
  • Noun to verb: this verb is usually the action that is done with the noun:
    • martile = hammer ➜ martila = to (use a) hammer
  • Adj to noun: the name of the quality of the adjective most probably
    • beli = beautiful ➜ bele = beauty
    • kibeli = ugly ➜ kibele = ugliness
    • fasti = fast ➜ faste = velocity
    • egi = big ➜ ege = size
    • tali = tall ➜ tale = height
  • Noun to adj: usually "related to noun" or "for noun"
    • cate = tea ➜ cati = for tea
      • cati peye = a cup for tea
    • myawe = cat ➜ myawi = for cats

One syllable verbs

All verbs are regular in Terwene, 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 very root contains at least one vowel, and every verb ending contains another one, so no one syllable verbs exist. In Terwene, I decided to have a limited amount of one syllable verbs (11 to be precise), which are the most commonly used, their roots contain no vowel (ex. sw-, h-, ky-, etc.). This way speech can be a bit faster.

The verbs are:

  • swa = to be
  • ha = to have
  • pwa = to say
  • da = to give
  • fa = to do/make
  • kya = to want
  • la = to go
  • xa = to like
  • nya = to need
  • ca = can / be able to
  • dwa = must / should / to have to

When using these verbs for word combination, it will usually be better to use the full infinitive (-a) or the noun (-e) rather than the bare root: nye + rume (need + room) = nyerume (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 (nya -> nye = to need -> a need), but sometimes it might be necessary to leave the -a ending and add -e after it (nya -> nyae).

Having these short verbs will surely create some ambiguities, "hola" means "to come", formed with ho- + l-, but maybe at some point there will be an independent word "hola" 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 "-i leye" 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
  • oe = way

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

As seen previously, "ke" is used as the word "than" for comparisons:

  • Ta swa mas boni ke tu = He is better than you
  • Ta swa kimas tali 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 sia ke ta swa en os te dome = I know he's in his own house
  • Mi tafaha ke date no swa ipli = I understand that's not possible
  • Mi no sia ke ta swel 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 swa wome ke dorma hoer (instead of "xenule") = He is the person who sleeps here
  • Data womire, ke te dome swa egi, swa mi te penge (instead of "xenule") = That man, whose house is big, is my friend
  • Tu swa ke te aytise? (instead of "xenule") = Whose mother are you?
  • Tu lega ke kitabe? (instead of "xeni") = What book are you reading?
  • Date swa ke? (instead of "xene") = What is that?
  • Mi te awte swa ke? (instead of "xener") = Where is my car?
  • Kos ke tusu fa 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 Terwene, 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
Wanote Dosote Sanote Kwarote Kwinote Lowote 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
Wanlune Doslune Sanlune Kwarlune Kwinlune Lowlune
July August September October November December
Cilune Colune Nawlune Tenlune Tenwanlune Tendoslune

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

  • Mi naska ces sani hore he dosabe dosarote tenwani (rote) de kwarlune wan naw naw co
    • I was born at 3:30 Tuesday the 20th of April 1998
  • Mi dormel dur lunabe = I slept during one week

Common phrases

  • Haye = Hi/Hello
  • Boni rote = Good day (at any time)
  • Boni solime = Good day (during daytime)
  • Boni kisolime = Good night
  • Boni morne = Good morning

Addressing Esperanto's inconsistensies

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:

  • ayte = 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:

  • aytayte = grandparent
  • aytiraytise = the mother of my father
  • ermihe = nephew/niece
  • ayterme = uncle/aunt
  • aytermespe = uncle's/aunt's spouse
  • aytermihe = cousin
  • ihihe = grandson/granddaughter
  • ermisite = younger sister
  • ermirege = older brother
  • ermespire = a sibling's husband
  • and many many more...

Short words not worthy of being classified

Some words and phrases in many languages like "very", "too", "and", "but", "at least", "still" and so on, are difficult to classify and usually don't follow the same rules. In Terwene that means that these words don't take any ending in their usual form. Here is a list:

  • He and

Person, human, man and woman

The word for human, man and woman is "wome" 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 Terwene numbers as prefixes.

Number of carbons 1 2 3 4 5 6 7 8 9 10 11 12 20
Prefix wan dos san kwar kwin low ci co naw ten tenwan tendos dosten


  • Wanalkane = methane
  • Dosalkene = ethene
  • Tenwanalkine = undecyne

This is just an example. Similar prefixes and suffixes can be created from Terwene'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.
