Everything You Know About “How Many Languages Can a Human Learn and Maintain?” is WRONG. Here’s Why…

Possibly one of the emotionally charged topics in the language learning world (and one that no one has good answers to, myself included) is the topic about how many languages a human being can learn.

We will never know the answer to that questions for way too many reasons. Here are some of them:

  • While most language enthusiasts haven’t thought about it (or have been put in a position to think about it), the language vs. dialect debate is getting increasingly muddy. Should the Caribbean English Creoles count as separate languages? The ISO 639-3 codes seem to think so. But would governments think so? How about universities? And obviously different areas where this question is more relevant will approach it differently (such as Jamaica and Italy, two completely different countries).


  • There is no definite way to quantify or even qualify proficiencies (except for, maybe, extended interviews on tape or eyewitness accounts of polyglots at conferences or gatherings). Even test results aren’t safe, given how many people may pass them and proceed to forget everything. (And if people can forget their native language, this is certainly also a possibility).


  • Human history and, by extension, history of human languages, is too long and too varied to take all the variables into account. I may have said this before in another one of my articles, but in some places like Western Africa or Melanesia, speaking ten languages is seen as normal. In many areas of the west, especially former British colonies, ten languages is seen as nearly superhuman if not in fact outright disbelieved by some people. This is despite the fact that there is no dearth of polyglot videos on the internet.


  • In addition to that, different areas of the world and different time periods would measure fluency differently. Mezzofanti, considered by some the greatest polyglot of all time, obviously had no usage for words pertaining to computers in any of his languages given as they did not exist when he was alive. He probably didn’t need to discuss complicated matters of science, either. Also (and this is another thing a lot of languages gurus don’t even realize because the languages they tend to choose) not all languages on the planet have that vocabulary. (In the event that you would talk about it, you would possibly use loanwords, primarily from a colonial language, or even switch into English or another colonial language periodically. However yes, there are some languages that have that vocabulary even though you think they might actually not.)


We will never know the answer to how many languages a human being can possibly know, and I highly encourage you to distrust ANYONE who tries to come up with an answer to the question. Because in attacking the question, they get the methodology wrong for all sorts of reasons.


Here are some of them:


  • Only taking into account their language experiences and those of their friend circle, which tend to be overwhelmingly skewed mostly towards politically powerful languages of Europe and sometimes Asia. Dialect continuums are not accounted for. If you think that Italian and Spanish are the equivalent of closest languages there are, give it some more thought. The Persian Languages are even closer, as are the “BCS” languages (Bosnian, Croatian and Serbia) not also to mention my own pet languages, the Melanesian Creoles (of Tok Pisin, Pijin and Bislama). Not all language counts are created equal, and this point alone would be capable of disqualifying the question altogether, but I’ll go on.


  • Not realizing that technology has changed and will continue to change. Mezzofanti didn’t have Memrise and many of the memory tools that I use on a daily basis. Technology has the capability of turning us into superhuman versions of our ancestors. An average person who has trained with contemporary first-person shooter games (which I never play, by the way) would have significantly better reflexes and hand-eye coordination than pretty much ANY soldier that fought in the Second World War. They would be considered SUPER SOLDIERS back then (this was a factoid I picked up from the 2016 Games for Change Conference). But for some reason almost no one considers that a similar thing is also happening for language learning and skill acquisition.


  • Using Ziad Fazah’s “Viva el Lunes” performance in order to automatically disqualify anyone who claims to speak 50+ languages. For those unaware, I’ll summarize it in one sentence. Liberian/Lebanese Polyglot who won Guinness Book of World Record’s title for most multilingual person goes on Chilean television, is tested and struggles even with basic sentences in most of his languages. But to dismiss any claims of that nature just because of ONE incident is a logical fallacy, and while I haven’t met anyone who has significantly pulled off that number, I wouldn’t automatically revert to skepticism. Just because of one person who may have likely overestimated his abilities doesn’t mean that we as a species should hold ourselves back. Who knows? There may be someone who may actually speak 59+ languages and who actually CAN show the skills. You never know!


I get it. A lot of people have deep insecurities, including many in the polyglot community. The temptation to knock others down or be dismissive only shows defensiveness and maybe a poor attempt to hide your own imposter syndrome. This is why I’m willing to consider anyone’s language proficiency based on claims alone (note I said “CONSIDER” not “definitively judge”, because there is no way to really do that.)


  • Using data about famous polyglots that have been dead for centuries (or even those that are STILL ALIVE) in order to draw conclusions as to what human beings in the 21st century can do. Really? In the case of the ones that have been dead for hundreds of years, they’re not relevant to our brains and our technology and our learning abilities NOW. Maybe they could be used in order to speculate about limits before the technological revolutions that happened during my lifetime, but we’re changing now and most people who answer the “how many languages is it possible to know?” question don’t acknowledge how contemporary technology sets our time period apart.


  • Different vocabulary thresholds for different languages. One person whose opinion I very much value said that a vocabulary of about 16000 words were required to reach a C2 level (the highest possible level, considered equivalent to a highly educated native speaker) in a language. But here’s the thing: in Bislama (an English Creole that is the primary language of Vanuatu), there are literally about 4,000 words (excluding proper nouns, which would bring the count up to 7,000) IN THE ENTIRE LANGUAGE. So if you speak with one-quarter of that amount with some languages, you get a near-native vocabulary, an advantage not afforded to languages like French and Swedish with significantly larger vocabulary lists (Swedish’s list of loan words from English ALONE is likely larger than the comprehensive vocabularies of the Melanesian Creoles COMBINED). And before you say “well, that’s just concerning Creole languages”, the same variety of comprehensive word counts can also be found the further away you get from the developed world AND the further you delve into languages without as much political support.


If there is a definitive limit for amount of languages learned, even to a high level, we will never know what it is, in part because of all of the factors that I lay out here.


It’s an interesting mental exercise that, let’s be honest, is usually used to discourage people and create skepticism so that some people can have their egos buttressed, but it’s one with no definitive answer (in the Talmud, we end such debates with the word “teyku”, meaning “let it remain unresolved”. And that’s what we’re going to have to go with this debate as well.)


What do I intend to do? Well, for one, I’m going to try my best and learn many languages, some to fluency, others to degrees of curiosity, and I fulfill MY vision. Because if you constantly live in the fear of judgment of others, you’ll never live your full life.


And that’s something you deserve to do! Don’t let ANY discouragement get you down!

come back when you can put up a fight

I really need to start using new pictures of myself.
