Suppose we want to translate the whole of Wikipedia from English into Lojban, what are the main known big limitations or concerns we should be aware of? In other words, does Lojban as a language have sufficient expressive power for being translated from English?

  • There is a Lojban Wikipedia. – Corbin Feb 8 '18 at 23:35
  • A considerable amount of texts (from a conlang point of view) has been translated to lojban; perhaps it doesn't answer you answer, but it's at least convincing. – mklcp Feb 9 '18 at 12:53
  • One limitation: I'm reluctant to study it because I find its words ugly. – Anton Sherwood Oct 9 '18 at 18:30


A few things. First, Lojban often needs longer sentences to express something than it does in, for example, English.


Secondly, Lojban's vocabulary isn't that big, especially in the domain of sciences. Words would have to be calqued, adapted from English, French, etc. or completely re-invented.

Loaning and naming

Thirdly, the English language (and many natural languages) loans words directly (for example, champagne could be *shampain and buoy could be *boy or *boi) without changing spelling (a slight counterexample would be German, which often changes the letter c pronounced [k] to the letter k, like Kanada and Vokabular).

Lojban doesn't. .Romas. is Rome (Italy), .xavanas. is Havanas (Cuba) and .lidz. is Leeds (UK). This makes it confusing in some cases. How would Lojban adapt Turra Coo or people like Nelson Rolihlahla Mandela? The name should stay recognisable but pronounceable.


Furthermore, many rhetorical devices such as these would be boring, simply boring. Shakespeare would be an ordinary novel writer, the Bible no longer so majestic and this sentence boring. Language would be unambiguous: literature boring. Language needs rhetoric, rhetoric needs language. Epizeuxis. Epizeuxis. Epizeuxis. Alliteration acts amazingly when all aposiopesis achieves is... Aposiopesis achieves... Aposiopesis... Rhetoric is not unlike magic. What would we have without rhetoric? We'd have a boring and a world. Rhetoric, her voice is beautiful, her heart full of peace and her prosopopoeia angel-like.

Well, to finish that rant, try to translate this to Lojban.

A shocking affair occurred last night. Sir Edward Hopeless, as a guest at Lady Panmore’s ball, complained of feeling ill, took a highball, his hat, his coat, his departure, no notice of his friends, a taxi, a pistol from his pocket, and finally his life. Nice chap. Regrets and all that.

  • And though Lojban handles such slightly modified loans (called stage-2 fu'ivla), loaning many words would be a bit lameful, since Lojban has also a system to build compound words from native root-words. – mklcp Feb 13 '18 at 21:39
  • Also, not more puns with Lojban. – Duncan Apr 23 '18 at 8:47

    I don't see how any of these are limitations with Lojban specifically. The length of a translated text is always going to vary from the source, and may often be longer because you have to include fluff to express information you naturally express in one language but not the other. Vocabulary can be built on, especially with compound words and loans. Why should loanwords be spelled the same as their source language, and trick readers into horribly mispronouncing names? I spell "karate", not 空手道. I also wish to see how you would translate that quote in any naturalistic language. – TUSF Sep 16 '18 at 20:29

One of Lojban's most famous features is, of course, its lack of syntactic ambiguity. While this is an advantage in some cases, it can also be a limitation. It wouldn't likely be an issue in something like Wikipedia, but does make certain kinds of wordplay impossible. Take for example this exchange from Lewis Carroll's Through the Looking Glass:

'Who did you pass on the road?' the King went on, holding out his hand to the Messenger for some more hay.

'Nobody,' said the Messenger.

'Quite right,' said the King: 'this young lady saw him too. So of course Nobody walks slower than you.'

'I do my best,' the Messenger said in a sulky tone. 'I'm sure nobody walks much faster than I do!'

'He can't do that,' said the King, 'or else he'd have been here first.'

In Lojban there is no way to conflate "nobody" meaning "no person" with "Nobody" meaning "someone named Nobody", because proper names are always preceded with the article "la". Other works that rely on wordplay based in syntactic ambiguity would also present major difficulties in translating to Lojban.

That said, there is a Lojban translation of Alice in Wonderland, so these difficulties aren't necessarily insurmountable.

    But some languages also are unable to translate it and would explain the English version. In that way, Lojban is like those languages and the difference is not per se constructed but natural too. – Duncan Feb 21 '18 at 19:24
