Questions and answers

topWhat is Mundeze?

Mundeze is an international auxiliary language project (IAL or auxlang or interlanguage), i.e. a language constructed with the aim to be used like lingua franca all over the world. There are thousands of dialects in the world, and this great richness unfortunately has some drawbacks: a brake on trade and knowledge sharing, high translation costs, misunderstandings, manipulations, etc. There are many different dialects in the world. An IAL would alleviate many of the problems of international communication, and it’s for this purpose that Mundeze was created, in order to make a language as easiest and instinctive as possible. Its main characteristic is to allow speakers knowing as many words as possible without ever having learned them, and to be able to guess the meaning of those they have never heard, based on the consistency of word formation and an etymology often onomatopoeic.

topWhere does the word “Mundeze” come from?

Mundeze is a word made up of roots mund– (world) and ezo (language, dialect). This term can be translated as “world language”. This name has been temporarily assigned to the language waiting to find one collectively 😉

topOne language for the world?

Mundeze does not pretend to replace other languages, quite the contrary. A neutral auxlang would also make it possible to level the other languages by eliminating domination of one language over another.

The idea is to encourage the teaching of Mundeze as a second language throughout the world, so that it serves as an easy communication tool between people who cannot communicate efficiently with natural languages.

topWhy not English?

It is true that English already serves as effective international auxiliary language in almost every country, mainly as a business language. However, despite its qualities, English is far from being an easy language, both from the point of view of pronunciation, spelling, phrases, idioms and the many exceptions. Moreover, it is a culturally very marked language, i.e. it lacks neutrality.

topMundeze is an artificial language, right?

Yes, like every other language in the world. All languages were created by men, but they evolved in a natural way, regardless of the exceptions and other difficulties added to them.

On the other hand, auxiliary languages built like Mundeze are created scientifically, not only for the purpose of communicating, but also to be easy and coherent for everyone.

topWhy not Esperanto?

Esperanto is the most successful auxiliary language, and today has hundreds of thousands of speakers worldwide. It has great characteristics, but still has aspects that discourage many learners (accusative, diacritical, gender treatment, agreements and other unnecessary or inconsistent difficulties), which is why there are so many reform proposals.

topAre there still other IAL?

In addition to Esperanto, there are many other auxlangs, such as Volapük, Ido, Nov-esperanto, Occidental, Interlingua, Novial, Glosa, Kotava, Angos, Ayola, Uropi, Sambahsa, Kah, Tceqli,Lingwa de Planeta, Atlas language… A lot of others projects are on creation or archived, like Ardano, Womese, Arlipo, Atlango, Intero, Sarata, Eselano. Others are presented via the magazine Posta Mundi, the brochure Daughters of Esperanto, or the blog Nuntios.

But the auxlangs that stand out most from the others, by their simplicity, are for us: Pandunia, Fasile21, Lingua Franca Nova, Esperanto sen fleksio and Mondlango.

topWhat are the benefits of Mundeze over the other IAL?

Mundeze is above all a systematic language, in which each characteristic, each rule, each morpheme is generalized to all aspects of the language. Anything that could be a difficulty for foreign speakers has been eliminated or made optional (case, gender and number agreement, conjugation, articles, plural, etc.).

The grammar is extremely concise and quickly assimilable, and everything is designed to make it a language that is simple, logical, consistent and instinctive.

topWould a language too simple lose linguistic wealth?

No doubt, but as an auxiliary language, Mundeze has no other ambition than to serve as a tool for understanding each other effectively.

topHow could one teach Mundeze all around the world?

There is no chance for an auxlang such as Mundeze to be taught in schools in the current context. Even Esperanto, which has a relatively rich literature and many speakers, has almost no chance of ever serving its purpose. The adoption of an auxlang depends on political will, but just as a long-term vision would have made us adopt renewable energy instead of hydrocarbons, the leaders of our society will have no interest in launching programs to establish a new auxiliary language for the future.

The success of Mundeze, or any other constructed language, therefore depends both on its popularization in the world to give it a legitimate character, and on a change of socio-economic system.

A revolution would bring all international auxiliary language projects to the same level, and the choice could then be made on an efficiency criterion that Mundeze has a good chance of winning.


  • I think Fasile21 is dead.
    It should have been open-source.

  • The entry:
    “What are the benefits of Mundeze over the other IAL?”
    does not really answer the question.

    What are the advantages over:
    Pandunia, Lingua Franca Nova, Esperanto sen fleksio, Mondlango,
    (and now Lidepla, Globasa…) ?

    All of those also claim that:
    The grammar is extremely concise and quickly assimilable, and everything is designed to make it a language that is simple, logical, consistent and instinctive.

    • That is a very good question, but it’s impossible to give “absolute” arguments as long as preferences are “relative”.

      All the languages you mentioned are great, but their strengths are not seen as such by everyone.
      For example, I find the system of grammatical endings to be extremely effective, but Globasa prefers to be as isolating as possible, and that’s a definite advantage, but… not for me.
      In my opinion, this is done at the price of many sacrifices, but this is only my opinion and I don’t pretend that mine is the best.

      According to MY OWN criteria, Mundeze is obviously much better on all the stated points: coherence, systematization, instinctiveness, objective ease…

      I find that Mundeze manages to express a lot of things without resorting to new tricks, just by making good use of existing mechanisms, and I find that it does so much better than the other auxlangs.

      My preferred auxlang is Pandunia. I think it’s great, so I’ll limit the comparison to this one so I don’t write a book hahaha.

      – In Pandunia, pronouns all use the same vowel, which can cause confusion in a noisy environment.
      – The endings are not systematic, which can be confusing… If I know the adjective “suyi” (watery) (hard to pronounce), I would infer that “water” would be “suye”, whereas it’s better to say “suy”. How could I know? And if I can say “suy”, what rule would prevent me from saying “kek” instead of “keke”, when so many other nouns end with another letter, especially since there are such suffixes as -er or -ia. I think they are excellent suffixes, which sound very natural, but I personally give priority to systematism rather than naturalism.
      – Moreover, I think it’s a pity that suffixes only make sense when they are attached to a radical.
      – Speaking of suffixes, I regret that there are two reversive affixes, depending on whether it’s a verb or an adjective…
      – There is no way to differentiate whether a derived adjective is static or dynamic (fobi hewane = scary animal & scared animal). You must use other formulations (with the particles “da” and “du”: “foba du hewane” & “fobu du hewane”)
      – The -a and -u endings are ingenious, but very confusing.
      – Besides, the ending -u expresses both the passive and the stative. Example: me fuku = I am dressed / I’m getting dressed
      – The reflexive pronoun is interesting, but it doesn’t hold up in complex sentences. Once I asked Risto for more details, and he told me that the reflexive particle “ze” always relates to the subject. However… if I say “Me pliza mame waxa ze” = “I ask mummy to wash me”? No… it relates to mummy, the object of “pliza”.
      – Many words are borrowed from tonal languages while maintaining Latin spelling, making them incomprehensible to a speaker of the source language.
      I find that drawing vocabulary from many languages has the merit of making the language more neutral, but less recognizable internationally. I also find that Pandunia creates too many new roots when it’s possible to create many new roots from the existing ones.
      – etc.

      Ok, Mundeze also has flaws. Derivatives aren’t always reversible like in Ido, but it’s a choice I made to gain instinctivity. For example, blood is “sange”, but bleeding is “sangi” instead of “sangsenisi” (losing blood).
      I think it’s more instinctive.
      Everything is a matter of choice, and these choices are made according to subjective criteri and, according to my criteria, Mundeze deserves to have its place among the others, because for me it’s much better.
      I repeat, I love Pandunia. I would have much more to say about other auxlangs, even though I love them in some aspects as well.

  • I miss a section about the birth of Mundeze.
    Why, by whom?

    Esperanto’s birth is famous.

    Lidepla was made by a group of linguistsin Russia, having studied all other previous IAL and finding problems x y z in them.

    Globasa by a linguist and language teacher having spent years on the development of the language.

    What about Mendeze?

    (Mandatory reference: )

    • yeah I knew this comic, it’s so true hahahaha. But imo, the multiplicity of projects is not a weakness, but a strength. Many people think that there is a fixed number of people who are interested in auxlangs, as if everyone would turn to Esperanto if there was only Esperanto. That’s not true. Some people are interested in auxlangs precisely because there are different projects.

      I speak 7 languages, and initially I became interested in vehicular languages when I realized that language conflicts don’t exist in Congo (where I grew up) whereas they are very present in Belgium (where I currently live). Yet there are 100 times as many languages in Congo, but the difference is that there is a “neutral” official administrative language (French). I thought about what language could be used as a lingua franca in Belgium, and that’s where I became interested in Esperanto.

      I (Djuna de Lannoy) made Mundeze in 2012 after learning Esperanto, and after becoming interested in other auxlangs (Ido, Novial, Uropi, Mondlango…) but there were still too many aspects I didn’t like. If I had known Pandunia or Elefen at that time, I probably wouldn’t have created Mundeze… but now I don’t regret it.

    • Very nice story about Congo and Belgium! You should definitely use it more on this site!
      People might discover and get interested in auxlang because of how varied they are, that’s true.

      But I can’t help thinking that for a language to be used, people have to first learn it, and learning a language is hard (well, not for you apparently, 7!).
      So hard that, I would want to learn one language to communicate with everyone. And I think having many similar auxlangs makes it much harder to pick one, so people pick the one with actual speakers, Esperanto. It’s “good enough”. I did.

      Also, if there were 4 neutral languages in Congo, would French work as a vehicular language, do you think, or would there be languages conflicts?

      • When you talk about neutral language, are you talking about non-native language? If so, I don’t think it’s possible.
        Different regions could have different lingua franca, but the same region cannot have several lingua franca. One of them would very quickly end up imposing itself on the others. However, if you were to hypothesize that different regions of the same country have different neutral languages, I think that could indeed generate conflicts, but I think they would be less passionate as long as they are not mother tongues, since it doesn’t directly affect your community. A few rare countries are experiencing this situation, such as Cameroon, which, in addition to the local languages, has French and English as administrative languages.

        Regarding the motivation to learn a language, you must have realized (in the last question of the FAQ) that I have a strong opinion on the subject, which differs greatly from that of most auxlang creators.
        I don’t think it’s enough for a lot of people to learn an auxlang for it to become the new IAL. Its learning must be included in the school curriculum, as is the case with English currently, so it must come from political will.
