The Science of Swearing

Note: this post contains ~naughty~ words. If you have sensitive eyes, cover them now!

When I first started this blog (which is a university assignment), I was told “no swearing allowed.” This was deeply disappointing to me, because ya know, sometimes a swear word just fits perfectly. Take for example, the ever-non-PC Paul Henry, who recently let “clusterfuck” slip on live television:

Video via Nic Hudson on Youtube (thank you to my mother for alerting me to this incident and sending me the link)

Clearly, clusterfuck was the ~ideal~ word for this situation. It just fits so well.

So this post is all about swearing. Why do we do it and where do swear words come from?

But first…

…I’d like to clear up a common misconception. Some people disparage those who swear by claiming that cussing demonstrates a lack of intelligence and creativity.


This is quite simply a steaming rotten turd of an idea.

A recent study examined this preposterous hypothesis and found that those who know more swear words also have larger vocabularies in general.

They asked participants to rattle off as many profanities as they could in one minute. The study subjects came up with an impressive 533 “taboo” words including classics like shit and more obscure terms like cum dumpster.

Participants then listed as many animals as they could in one minute – this was used as a kinda proxy indicator of the subject’s overall verbal fluency (in addition to some standard vocab tests). A larger repertoire of curse words correlated with a generally larger vocabulary.

So there you have it. As Stephen Fry so eloquently put it,

“The sort of twee person who thinks swearing is in any way a sign of a lack of education or a lack of verbal interest is just fucking lunatic.”

Where do swear words come from?

The words we consider profane usually relate to taboo subjects: like sex (fuck) or body parts  (tits) and functions (shit). They can also include animal names, blasphemy or racial/gender slurs. To some extent, it is institutions of power or broad societal structures, like the media and religion, that define what constitutes a swear word.

“Swear words are the wild weeds of language – wiry and gleeful, flourishing on the edges of horticulture, for there, on the boundary, rejected language growls robust as weeds, like demented nettles sniggering with brambles and thistles making mischief with the grass.”

Jay Griffiths, from Wild: An Elemental Journey

But taboos change over time – which means our swear words do too. Back in the 1800s, all kinds of words we use regularly nowadays were considered scandalous. According to Bill Bryson in his book The Mother Tongue, when referring to a chicken, the words breast, thigh and leg were no-nos. Instead, you would say white meat, first joint and drumstick. Bulls weren’t bulls either – they were male animals or gentleman cows.


Gentleman cow

Luckily, those days of drastic sensitivity are behind us. Today, we have a range of swear words that vary from the mildly offensive (crap) to the extremely profane (cunt). On a side note, cunt hasn’t always been such a obscene word. It was imply a factual term for female genitalia. Hilariously, a common street name in Medieval England was Gropecunt Lane – presumably this indicated the location of the red-light district.


What about expletives in the brain? Turns out, swear words aren’t really words. They’re more like instinctive outbursts of emotion. Normal language is formed in Broca’s area and Wernicke’s area – but swearwords originate in the limbic system, the brain’s emotion centre. This leads us on to ask the question…

Why do we swear?

“Swearing is like using a horn in the car, which can be used to signify a number of emotions.”

-Timothy Jay, in The Utility and Ubiquity of Taboo Words


Swearing is beeping the car horn

We use swearwords to express anger, frustration or surprise. Take the word fuck as an example. Fuck is an underrated word in the English language – it’s incredibly versatile. I could say “fuck off” if I wish for you to leave. Or I could say “he’s just fucking around” to describe someone who is messing about in a casual manner. I could say “fuck this!” to express frustration and exasperation. Or I could say “fuck yeah!” to emphasise excitement.

Profanity can be used to insult people – and the inclusion of a swear word is especially rude and mean. (Don’t do it, guys!)

But swear words aren’t always bad. They are important for catharsis and anger management. In fact, one study found that swearing can increase pain tolerance. So the next time you stub your toe, feel free to vent with a good curse word or two.

Swearing also has positive roles in a social context. People that share a similar vocab, and who break taboos together, form bonds. Swear words can be used in storytelling, jokes or social commentary. We even use some swear words as terms of endearment in certain social situations (dickhead, bitch, good cunt).

This highlights how social context shapes the meaning – and offensiveness – of swearwords. If you’re at a business meeting, it’s probably not a great idea to sprinkle your speech with fucks and shits. But in less formal settings, in the company of people you’re comfortable with, you’re more likely to drop fucks like a trucker.

And we do swear quite a lot. The average person’s speech consists of 0.5-0.7% naughty words. To put this in context: we use personal pronouns (I, we, you) 1% of the time.

So now you know all about the science of swearing, and I hope I’ve convinced you that swearing isn’t all bad – in fact, sometimes it’s pretty fuckin’ good.

Distant Shores: Did Polynesians Reach the Americas?

There’s all kind of weird stories floating around about Vikings and Celts and Phoenicians sailing around the globe, reaching various distant lands. They’re mostly crackpot conspiracy theories with little supporting evidence.


Vikings meet Polynesians in the South Pacific? I don’t think so.

But recently I’ve stumbled across one tale of a voyage across vast seas that is defs mainstream-science, thanks to a comment left by the author of Librepost on my Endangered Tongues article:

“…if you really want to hear about an unknown language, try searching for MAPUNDUNGUN, which discoveries are showing may have a Polynesian connection (in South America).”

How intriguing! I had to know more about this linguistic mystery. So I had a chat with Prof. Lisa Matisoo-Smith, a professor of Biological Anthropology at the University of Otago, who studies the settlement, history and prehistory of the Pacific.

A Mapuche Connection?

The Mapuche are Indigenous people who live in Southern/Central Chile and Argentina. Their native tongue, Mapudungün, is a language isolate – that is, a language that doesn’t appear to be related to other languages. (See here for a post on language isolates).


Image via Wikipedia (CC BY-SA 3.0)

Mapudungün is considered endangered by the UNESCO Atlas of the World’s Languages in Danger. It’s thought that while there are more than 1 million people with Mapuche heritage, there are only around 200,000 speakers. And politics isn’t helping the Mapudungün survival-sitch either – it’s not an official language of either Chile or Argentina, plus there’s an ongoing debate about which alphabet to use for written Mapudungün. Let’s hope everyone sorts their shit out for the sake of this mother tongue.

But anyway, what do the Mapuche and their language have to do with Polynesia, 10,000km away? Well, there’s evidence that Mapudungün has been influenced by a few other lingos: Quechua (another Indigenous South American language), Spanish and also Polynesian languages. Ooooohh! Did the Polynesians, who were master sailors and navigators, reach the distant shores of South America?

Linguistic Links


The word toki is found in both Mapuche and Polynesian languages – it is a potential loanword. Prof Matisoo-Smith explains:

“There’s similarities linguistically related to the toki, which means adze. In Mapuche, the chiefs will often wear a stone adze necklace called a toki kura. And toki in Polynesian languages also means adze. Māori chiefs or high ranking individuals would also wear a greenstone adze or a stone adze.”


A toki is a stone adze worn by chiefs in both Mapuche and Māori cultures

Pre-European toki have been found at archaeological sites in both Chile and Polynesia, and this combination of linguistic and ethnographic evidence suggests some sort of cultural exchange.

Canoe technology

It’s not just toki either – the Mapuche also have distinctly Polynesian boat technology: the sewn plank canoe.

“Most North American – like Northwest Coast – use dugout canoes and then in South America you’ve got things like rafts and reed boats. But the actual process of creating a canoe by sewing planks onto a hull is a Polynesian design and it’s found in two places in the Americas – one right around the Channel Islands, and one down in Southern Chile in the Chiloé and Mapuche area.”


The Chiloé Islands are depicted at the top of this image. Via Wikipedia (CC BY-SA 3.0)

The presence of this canoe technology in South America is a pretty credible clue hinting that Polynesians reached the western coast of South America. A UC Berkeley linguist, Kathryn Klar, has investigated this even further, by taking a good look at the words used in Chiloé Island languages associated with canoes.

Looking at the languages in this historically linguistically diverse region is pretty tricky. Many have since gone extinct, and the data that remains is from aaages ago.

In a language from this area, recorded in 1839 as “Patagonian,” we have

tă lĭnă and tă lĭnă cărrŏ

meaning ship and boat respectively. Klar reckons tă lĭnă comes from the Central East Polynesian word for “worked wood” (tumu rakau), while cărrŏ is the native Patagonian word for boat. So, this language borrowed a Polynesian word to differentiate sewn plank canoes from other watercrafts.

In “West Patagonian,” another Indigenous language recorded in Chiloé in 1917,


means West Patagonian canoe. Klar suggests this originates from a combination of Polynesian bases: tia meaning sew and loa meaning long.

“I’ve talked with a Chilean researcher who was working on Mapuche water rights and looking at the archaeological evidence for the canoe technology. So they’re finding these sewn plank canoes and they all date to about the time we would expect Polynesian contact to occur.”


A sewn plank canoe consists of planks of wood… you guessed it… sewn together

Controversial Kumara

The humble sweet potato that accompanies your Sunday roast may just seem like a tasty vegetable, but it’s also evidence of Polynesians reaching South America, picking up this humble root, and transporting it back and distributing it throughout the islands.


Attempted kumara cartoon

“The sweet potato, the kumara, is a root crop and is a familiar looking starch for Pacific people. They’ve been growing yams and taro, so they would have an understanding  of how to plant it and how to cook it – it’s a familiar type of food. That to me suggests some kind of a selection, ‘Oh we’ll take this, and we know how to preserve it and take it back, get it back home.'”

There’s also a linguistic connection between the Pacific kumara (and its variants) and the Quechuan word cumar, which is also used by Indigenous peoples on the coast of Ecuador.

It’s not just words…

…it’s also chicken genes. A Chilean archaeologist, José Miguel Ramírez-Aliaga, uncovered some chicken bones at an archaeological site in the Mapuche area which he believed were pre-Columbian. South America didn’t have chickens until they were introduced, and if they were pre-European contact, then who did introduce them..?

Ramírez-Aliaga got in touch with Matisoo-Smith, who was working on the spread of animals like rats and chickens throughout the Pacific. She analysed these chicken bones and radio-carbon dating showed that they were introduced at the latest by 1424 – definitely pre-European! Genetic evidence suggested these weren’t just any chickens either – these were Pacific chickens. This is excellent evidence for the presence of a few Polynesian visitors (and their chooks).


Polynesian chickens made it to the New World before Christopher Columbus

A few similar words and artefacts by themselves don’t mean much. It could simply be a case of coincidence. But the big picture of archaeological, ethnographic, linguistic and genetic evidence, with a dash of commonsense, makes a pretty compelling case for pre-Columbian contact.

“Most Pacific researchers would say that it is highly likely that Polynesians made contact with the Americas, just given the sailing trajectory that they were on. Consistently moving in that direction and you know why would they stop? They didn’t have maps or anything that said they’d gotten to the last island and they couldn’t go any further…”


Many thanks to Professor Lisa Matisoo-Smith.

How Sign Languages Can Teach Us About Language Evolution

In the midst of the mass language extinction currently afflicting our ethnosphere, there are bursts of linguistic life.

Sign languages!

Despite the loss of spoken languages, sign languages are springing up all over the place.


Despite the widespread extinction of spoken languages, new sign languages are emerging.

These new visual lingos don’t make up for the destruction of irreplaceable cultural heritage in the wake of an English-tsunami. But they do offer a fascinating insight into how languages emerge and evolve.

One reason Sign Languages rule

To study the birth of new languages, linguists have often turned to pidgins and creoles. A pidgin is a super-simplified form of language used to communicate between people with different native tongues. Sometimes, a pidgin language will develop its vocabulary and grammar – when it reaches this level of complexity and is spoken as the mother tongue of a new generation, it is called a creole.

But some linguists argue that these aren’t really ~new~ languages because they are heavily influenced by the two languages of the initial pidgin-speakers.

This is where sign languages come in. When they emerge in deaf communities, sign languages are shiny and new, language-newborns just squeezed out of human brain-wombs. These lingo-babies are ripe for studying the origins and evolution of language.


Emerging sign languages are RIPE for studying the origins and evolution of language.

Nicaraguan Sign Language

Up until the late 1970s, Deaf people in this Central American nation had been mostly isolated. But in 1977, a school for Deaf children was established. Education at the school focused on lipreading and fingerspelling of spoken Spanish. Aaaand as with other places where this “spoken” education was forced on Deaf people, it failed miserably.

But in the schoolyard and on the bus, something pretty magical was happening. The children were creating their own sign language. As younger children learnt these signs, they adopted more complex grammar by changing the position or direction of their signs. Idioma de Señas de Nicaragua (ISN) was born.


Nicaraguan Sign Language first emerged only a few decades ago in the late 1970s.

This got linguists pretty excited – and sparked some hefty arguments. Some linguists see the ISN case as confirmation of the idea that we are innately hardwired for language – that we have a “language acquisition device” in our brain. But others disagree – it could be just a general problem solving strategy that allows us to create languages for communication. There’s also a lot of debate about when exactly ISN became a fully fledged language.

Sign Languages in the lab

Earlier this year, researchers presented a study detailing how gestures become systematised into an artificial sign language over successive generations.

Volunteers made up manual gestures for 24 different concepts, like “photographer.” They then taught the sign to a partner. The partner then gestured the sign and other volunteers had to guess its meaning. If they got it right, the guessers taught that sign to a new generation. And so this iterative learning process continued. After a few successive rounds, the signs became more systematic and efficient, and more language-like, rather than simply acting out.

Check out the video below to see how pantomime evolved into a consistent sign:

An evolutionary model for language?

Nicaraguan Sign Language is just one of many emerging sign languages around the world – you could also check out Israeli Sign Language (ISL) and Al-Sayyid Bedouin Sign Language (ABSL).

Linguists studying these budding communication systems noticed that all these young sign languages, despite being found in opposite corners of the globe, evolved in predictable ways.

With each generation, signers recruited more parts of their body to communicate: from their dominant hand, to their head and facial expression, to upper body position and their non-dominant hand. This pattern was consistent across disparate languages.

These similarities hint at the tantalising possibility of a general model for language evolution. Perhaps this systematic evolution reflects some language brain software common to all of us? There’s still many questions to answer (and find), but baby sign languages offer us a promising approach to solving these evolutionary riddles.

This is Your Brain on Language

We all know it’s important to exercise regularly for optimal physical health. Similarly, our brains need a good workout to stay in tip-top shape. But forget that Lumosity brain-training crap.

Learning a language is a much more effective way to beef up your brainpower.

Buckle in for a whirlwind overview: This is Your Brain on Language.

Cerebral challenges

First of all, what exactly does your brain get up to when you’re imbibing a new language? It all starts in the ear, which transforms sounds waves into neural impulses. These are basically your brain’s way of encoding information electrically, kinda like an brain-radio.


This info is conveyed to the first pitstop for processing sound: the auditory cortex. This region figures out when and where the sound originated from.

Next up is Wernicke’s area, which turns random sounds into meaningful words and phrases. You understand what is being said, nice work brain.

If you then wanna reply, Broca’s area of your brain starts formulating your response.

Finally, you need to physically move your lips and mouth to make sounds. This is where your motor cortex comes in – it controls voluntary movements. Now we’re talking!

It’s pretty mind-blowing to think that your brain does all this lightning-fast. Thank you, brain.


Your brain does all this SUPER QUICK

So when you’re learning a new language, your brain has to learn how to distinguish which language a sound is coming from, so it can process it correctly. This requires a whole lotta memory. You have to use your declarative memory system – which deals with facts – to remember all those new words and grammar. Then there’s the procedural memory system – your lips and mouth have to remember which shapes to physically make. For tip-of-the-tongue fluency, you’ll have to subconsciously recall all this,  meaning it has to be part of your implicit memory.

Phew! No wonder languages are the ultimate workout. So why go through all this effort? Here’s a few rad results of language learning.

It can make your brain bigger

Yep, learning a language is literally the brain equivalent of bodybuilding.


A 2014 study used magnetic resonance imaging (MRI) to observe the effects of language learning on the physical structure of the brain. They compared the brain scans of language students before and after three months of intense study. For comparison, they included a control group of medical science students.

Med sci brains remained unchanged, whereas those grappling with a new lingo exhibited growth in specific areas.

Hold up! A bigger brain doesn’t necessarily mean a smarter brain. So you might not be more intelligent.

But you may be healthier, since brain size may indicate brain health. As you age, your brain shrinks, leading to cognitive decline and diseases like dementia. In fact, research has shown that being bilingual delays the onset of dementia and can protect against Alzheimers disease. Maybe bigger is better?

It can also change the structure of your brain

Your brain is plastic. I don’t mean like a barbie doll – this is a good kind of plastic. Neuroplasticity is the brain’s ability to reorganise itself, forming new neural connections.


Here’s an interesting tidbit: if you have grown up bilingual, then both the languages you speak are processed in the same part of the Broca’s area. But if you learn a language later in life, a new region develops in the Broca’s area, separate but close to your mother tongue.

But no matter your age, simply participating in language learning increases the density of your grey matter – the brain-stuff that incorporates everything from muscle control to decision making to sensory perception. Meanwhile, your white matter is strengthened. White matter is the tissue that connects different parts of your brain – kinda like a subway system for navigating the mind.

Essentially, the networks in your brain become more closely integrated. Consequently, you can learn more quickly and efficiently. Hell yeah!

How you learn a language – whether in a traditional classroom or by immersion – can affect how your brain is rewired, too.

You’ll be better at concentrating…

…and other things. A lot of other things. Seriously.

Researchers have found that bilingual people have enhanced attention – they’re better at shutting out irrelevant stuff and focusing on what’s important. What’s more, it doesn’t matter whether you learnt the language in childhood or as an adult, the benefit is the same. Similarly, being bi- or multilingual can make you a better listener.


Being multilingual can help you block out the haters

Learning a language can help you develop qualities that underpin creativity. You’ll also be better at multitasking – perhaps the result of having to seamlessly switch between two or more languages.

You will think more analytically and be more considered in your decision-making, as well as being less susceptible to persuasive language (the sort you might find in political campaigns).

Some people even reckon that different languages change the way you perceive the world.

So what now?

If this is your brain on drugs…

…then this is your brain on language.

It doesn’t matter how old you are or how fluent you become – just try to learn a language and you’ll reap the cognitive benefits. Yeeww!


How has learning a second language affected you? Let me know in the comments!




How many languages can a person learn?

If you’re reading this, you can speak English. Wicked.

Maybe you can speak another language too – perhaps your original mother tongue, or one that you learnt at school. Even better.

Maybe, just maybe, you have mastered a third or even fourth language – if yes, I am in awe of you.

Bu there are some scary-special souls out there whose minds soak up languages like a brain-sponge. They have an insatiable appetite for more, plus, lebih!

If a person can speak six or more languages, we call them a polyglot (meaning “many-tongued”).

If they’ve got 12 or more languages under their linguistic belt, we call them a hyperpolyglot.


A polyglot can speak at least six languages, while a hyperpolyglot can speak at least 12.

This post, we’re gonna meet a few of these mad-awesome mofos, explore the science of polyglotism and answer the question: who is the greatest polyglot of them all?

The polyglot-est of the polyglots

To answer this question, I consulted the trusty Guinness Book of World Records, home of all feats weird and wacky. I typed “language” into the search bar on their website, returning 106 results.

I scrolled through record after record, past the longest alphabet (Khmer/Cambodian) and the loudest click of the tongue, all the way to the end. And there was no record listed for “the most languages known.”

Wat. Why?

Turns out, this whole kerfuffle is pretty controversial.

First we’ve got the problem of what the heck defines a language? That is, what’s the difference between a language and a dialect? Sometimes the distinction between the two can be blurry…

But even more difficult to pin down is what it means to know a language. Obviously, rattling off a few bonjours and je m’appelles doesn’t mean you can really speak French. So at what point do you become fluent?

Perhaps we could get a native speaker to judge how well you can hold a conversation – but this is subjective. Maybe we could define fluency by comparing vocabulary size to native speakers – but it turns out you can converse at a high level of perceived fluency with a much smaller vocab than native speakers.

And what about reading vs. writing vs. speaking? How do we compare someone who can read and write in 20 languages, to someone who can converse simply in 40?

So. The lack of objectivity in defining polyglotism means we can’t really crown the polyglot-est person on the planet. Still, anyone who can speak multiple languages is frickin’ amazing in my book.

Meet the polyglots

Guiseppe Caspar Mezzofanti

This Italian Cardinal was legendary for his language prowess. It’s reported he could speak 39 languages “with rare excellence” but some sources claim he could understand a whopping 72. Either stat is impressive considering he never even left Italy…

Mezzofanti had a super-charged memory when it came to words, but he complemented his natural aptitude with long hours studying. Lesson learnt: you gotta work yo ass off if you wanna become a language expert! Read more.


Mezzofanti is reported to have known Algonquin – a language spoken by First Nations people in Ontario and Quebec. “Kwey” means “hello.” 

Emil Krebs

This German chap was passionate about languages. By the time he left high school, he could speak 12 of them. Throughout his life, he accumulated an astounding total of 65 languages – and he could tell you to “kiss my ass” in 40 of them.

After his death, Krebs’ “elite brain” was preserved and resides to this day at the C. & O. Vogt Institute for Brain Research in Germany. In 2003, neuroscientists examined his brain, and found it was wired very differently to monolingual people. But it’s unclear whether he was born with this set-up, or whether constant language learning changed the neural connections in his brain. Read more.


Emil Krebs could say “kiss my ass” in 40 languages. Go here if you’d like to emulate Mr Krebs.

Alexander Argüelles

During his childhood, Argüelles had an innate interest in language. But apart from high school French, he didn’t explore this interest to any depth. At university, however, the ability to read his favourite German novelists in their native tongue led him down the rabbit-hole of language learning. He spent 16 hours a day filling his brain with words and grammar, and now he can speak around 36 different tongues but has studied many more. Read more.

“I’m increasingly drawn to dead and endangered languages… I do think the loss of so many quirks and colours would leave the world a less intriguing place. It would be like visiting a botanic garden where there was only one type of plant – that thought horrifies me.”

-Alexander Argüelles, linguist

Powell Janulus

This Canadian fellow was in the Guinness Book of World Records in 1985 for “knowing more languages than any other human.” To earn this entry, he passed two-hour long conversational fluency tests with native speakers in 42 different languages. However at his peak, he claims to have known 64 languages. In 2006, Janulus suffered a stroke but has since resumed learning new lingos. Read more.

Dr Carlos do Amaral Freire

This Brazilian boss is considered perhaps the greatest modern linguistic scholar. He systematically studies two new languages every year, and has done so for the past 40 years. Consequently he has mastered 60 of them.

“I became captivated by the fascination of studying and discovering, through languages, so many other worlds, cultures and different ways of thinking.”

-Dr Carlos do Amaral Freire, linguist

Swami Rambhadracharya

Rambhadracharya is the ultimate slashie: a Hindu religious leader, philosopher, poet, educator… as my friend would say, he’s DA MAN. He can speak 22 languages and is considered a scholar in 14 of them. He writes poems and plays in a variety of lingos – but he can’t physically read or write. Rambhadracharya’s been blind since the age of 2 months, so he learns by listening and composes by dictation. Read more.


Rhambhadracharya is an accomplished polyglot (among many other things).

Sir John Bowring

A former Governor of Hong Kong and a political economist, this high-powered Englishman had a penchant for literature and language. It’s reported that he knew 200 (!) languages and could speak 100 of them. Whether these numbers are accurate, it’s difficult to say. But even if they are exaggerated, he clearly had an extraordinary talent and passion for language. Read more.

I’ve just picked a few polyglots so this is by no means an exhaustive list. Check out good ol’ Wikipedia for more multilingual masterminds.

Where da ladies at?

You’ve probably noticed that the above list is a real sausage fest. It’s true: lady lingo-lovers are relatively hard to come by. Others have noted this gender-skewing in the polyglotism world, but they haven’t found a good reason for it yet.

I had a good dig around and unearthed a couple of female polyglots:

Susanna Zaraysky

Zaraysky has studied 11 languages and can speak 8 of them fluently, and she is a great believer in the power of music to teach language. She’s written a few books and travelled the world, plus she’s passionate about inspiring more women to become multilingual. Read more.

Lomb Kató (or the westernised version, Kató Lomb)

Leaving behind her physics/chemistry background, Lomb took up languages and learned at least 16 (and maybe as many as 28). Lomb’s love of languages took her around the world as an interpreter and she also churned out a few books. She was one of the first simultaneous interpreters. Her drive to learn was characterised by unwavering determination and self-motivation. Read more.


Lomb Kató dedicated her life to languages and was one of the first simultaneous interpreters.

Savant or simply obsessive?

So what’s the deal with these tongue-twisting individuals? Are they wired differently from the rest of us?

Some have suggested that hyperpolyglotism is in some way linked to autism and/or savant syndrome.

But others believe that it’s simply a matter of hard work. Anyone can become a polyglot. (But certain personality traits and conducive life circumstances can help.)

And then of course, there’s those who reckon it’s a bit of both.

If there’s one thing you can take from these stories of polyglots, I reckon that it’s never too late to start. Wanna learn a language? Just do it!

Here’s an idea…

Here at Mother Tongues you’ll know we’re particularly interested in endangered languages. So ya know what’d be wicked? If polyglots could dedicate some of their burly brainpower to learning these disappearing tongues. What do you reckon?


Can you speak multiple languages? Let me know which ones in the comments!

Hotspots: Species Meet Languages in a Burst of Diversity

Scattered across the Earth, there are biodiversity hotspots – areas where Mother Nature flaunts her outrageous imagination like a peacock flaunts its magnificent tail. These places are hotbeds of evolution – not just for biological species, it turns out, but for languages too.


We’ve had an inkling of this language-species affair for a while. But it’s only in the last decade or so that we’ve quantified this connection.

Researchers collated information on where species live, and then mapped this against where languages are spoken. Using statistics, they found that high biodiversity does indeed correlate with high linguistic diversity.

F1.large (1)

(A) displays biodiversity hotspots around the world. (B) shows the geographic distribution of Indigenous languages. Reproduced from this paper.

They churned out some numbers for us to get a deeper sense of this link:

  • There are 35 biodiversity hotspots and five high biodiversity wilderness areas on Planet Earth – places like Amazonia, the island of New Guinea and the forests of Central Africa
  • These hotspots are home to 67% of all plants and 50% of all vertebrate animals (that’s A LOT)
  • They’re also home to 70% of the 6,900 languages spoken on Earth (whoa)
  • They used to cover around a quarter of all land on Earth – but this has dwindled down to just 8% (crap…)

Here are those numbers again, in visual form, if that’s more your thang:


But why?

Why should language richness and species diversity mirror each other like this?

As we’ve explored in previous posts, language and ecosystems are both complex adaptive systems. So it makes some kind of intuitive sense that they should behave similarly.

But let’s dig a lil deeper. What’s going on here?

Generally, tropical regions are both more biodiverse and linguistically diverse than desert and tundra areas. Perhaps, both types of diversity depend on similar environmental factors – like temperature and rainfall.

One possibility is that the abundance of natural resources in tropical environments reduces the need for groups to share and communicate with one another. So they don’t need a common language and the local lingos diversify as a result.

Maybe landscape barriers prevent communities from interacting and so different languages develop. After all, if a rugged mountain range separates you and your neighbours, you’re unlikely to pop over to say hello that often. Similarly, it is well-understood in biology that topographic barriers enable the evolution of species richness (this is a discipline called insular biogeography).


Topographic barriers may facilitate the diversification of both language and species.

It’s also possible that biodiversity sustains cultural diversity in a symbiotic relationship – the richness of one supports the other, and vice versa.

One kinda crazy-cool idea is that biodiversity provides a greater range of natural reservoirs for our imagination. We draw on our surrounding environment to construct metaphors that form the basis of our language. This enables different languages based on different metaphor-concepts to evolve. Language is infused with nature. Our culture is not purely a product of who we are – it’s also deeply rooted in our physical environment.

In turn, the metaphors used by many Indigenous cultures in biodiverse regions remind people that they cannot exploit their natural resources carelessly and endlessly. This allows high biodiversity to persist. What a beautiful cycle!

“For the forest people, nature is defended by culture. Many rules concerning hunting and the non-exploitative use of resources – blunt ecological truths – are encoded in myths and magic, tales and enchantments that make up a society’s culture.”

-Jay Griffiths, writer

It’s not simple…

It’s probably not just one of these explanations, but rather, some combination of them.

Take, for example, the rugged tropical jungles of New Guinea – home to a vast array of species, from birds of paradise to tree kangaroos. This island is also the habitat for nearly 1,000 distinct languages.


The island of New Guinea is home to some crazy animals – like tree kangaroos and birds of paradise. It’s also home to nearly 1,000 languages: “wiyo” means “hello” in Melpa and “wa” means “hello” in Dani.

Researchers zoomed in on this mother-tongue-menagerie to examine the language-species connection on a finer scale. Like previous global studies, they found a link. But the strength of this relationship depended on the scale you chose – the closer you zoomed in, the weaker the correlation.

This suggests that the link is multi-faceted – a complex brew of sociocultural and biogeographical factors.

In the case of New Guinea, the authors noted that the isolated, rugged highlands supported high biodiversity but low linguistic diversity, while the coastal lowlands were the opposite.

They suggested that lower malaria incidence in the inland regions allowed larger societies to form and language to diffuse among them. Meanwhile, elevated biodiversity was a result of the harsh terrain.

Madagascar is another interesting example. Its geographic isolation means it has a large proportion of endemic species (like lemurs and frogs). However it was only settled by humans around 2,000 years ago, meaning languages haven’t had much time to diversify.


Even though Madagascar is a biodiversity hotspot, it was only colonised by humans relatively recently, resulting in low linguistic diversity. The lemur says “how are you?” and the frog replies in Malagasy.

What this means for conservation

There are sad but thought-provoking parallels between species extinction and language loss. They are driven by similar phenomena: expanding human population, migration and globalisation. Some researchers have suggested that linguistic and biological conservationists should team up for even greater impact.

But the New Guinea study suggested that on a local level, threatened species and endangered languages do not necessarily overlap.

Nonetheless, conserving cultures is integral to saving nature. Indigenous people look after the land and so provide all of us with essential ecosystem services – clean air, pollination and fresh water. Their participation in conservation is vital – diversity ensures the future of humanity.

“When wild lands are lost, so is metaphor, allusion and the poetry that arises in the interplay of mind and nature.”

The Evolution of Language: Three Things We’ve Learnt

A coupla hundred years ago, our good ol’ mate Darwin thought up this totally radical idea called evolution. This had two noticeable results:

  • the church got their knickers in a twist,
  • and it revolutionised our understanding – of biology, humanity, pretty much EVERYTHING-y.

Cheeky Darwin and his pesky evolution theory got the Church’s knickers in a twist.

Since then, all manner of disciplines have co-opted the evolution concept: stellar evolution! Directed evolution! Music evolution!

Linguistics is no different. In my last post, I briefly compared biological evolution to language evolution. We also touched on this topic in our foray into the origins of language.

This time round, we’re gonna get fully sucked into the mind-bending twister of language evolution. Here’s three wicked things we’ve learnt from investigating how our mother tongues have transformed.



1. What Ancient People Were Like

By tracing the evolution of languages back in time, we’re essentially creating a knowledge-wormhole to ancient societies and their cultures.

Take the Proto-Indo-Europeans, for example. We talked a lot about their zombie PIE language in the previous post – but what I didn’t mention is that we can learn a lot about PIE society based on this reconstructed vocabulary. The words used by people are a mirror to their culture – in the PIE case, a ~~time travel mirror~~.

We know that the PIEs lived in a location with snow because they (and all their daughter languages) used the word sneigwh-. Similarly, we reckon they lived inland, because they didn’t have a general word for sea. We even know they worshipped a sky god and had domesticated both horses and cattle. You can read more about PIE society here.


Proto-Indo-European society didn’t have a specific word for “sea” so they probably lived inland.

2. How Humans Populated the Corners of the Earth

By examining how languages have evolved and diversified, we can also map out migration patterns across the globe.

For example, researchers built a phylogenetic tree of around 40 indigenous languages from North America and Central Siberia. This allowed them to construct a model of how the languages diffused across the two continents.

The results suggest that dispersal first occurred down the western coast of North America, followed by a “back-migration” into Siberia and then further diffusion throughout inland North America.

That is, there wasn’t a one-way migration from Asia to the New World via the Bering Land Bridge – human migration is more complex than we first thought. This lends support to the “Out of Beringia” theory.

Another migration-mystery that has bewildered researchers for aaaages is the “Austronesian Expansion” – or how the heck the Polynesians made it to all those tiny Pacific islands.

There are two main theories: a gradual settlement over 30,000 years (the “slow boat”) and a more recent “pulse-pause” scenario with ancestors migrating from Taiwan some 5,000 years ago.

To test these hypotheses, linguists constructed an evolutionary tree of Pacific languages. But they weren’t the only ones investigating this conundrum: biologists constructed a classic phylogenetic tree of a species of gut bacteria. By combining the evidence from both approaches, the scientists were able to discern the probable migratory routes – and they matched pretty well with the Taiwan-origin hypothesis. The “pulse-pause” pattern of migration was also replicated in the linguistic tree – it suggested one migration pulse of 7,000km over just 1,000 years.

Pretty cool, hey.


Linguistic evidence and genetic evidence from gut bacteria solved the Pacific migration mystery.

3. Language Evolution Really is like Biological Evolution

Evolution as a scientific theory has only been comprehensively analysed in its biological habitat. But it seems as though this concept may operate in a cultural domain too. This makes intuitive sense: cultures (and their languages) do change over time.

But the similarities go deeper than just a simple “shit changes” sense. Language is a complex adaptive system: it is an interconnected network of small, related parts (words) that work together to adapt to changes (cultural and environmental context) to ensure the survival of the collection as a whole (language).

Recently, some scientists have been explicitly adopting a Darwinian approach to culture.

In one study from 2008, linguists observed the evolution of an artificial language from random to highly structured, in a controlled laboratory setting.


The artificial language becomes more precise and more ordered over time – it evolves! Figure reproduced from this paper

These experiments revealed that, “languages transmitted culturally evolve in such a way as to maximise their own transmissibility.”

In non-wanky-science-speak: the language itself evolves in order to increase the chance it will be passed on (and stay “alive”). It’s like language is a cultural parasite, using human hosts to reproduce.


A language parasite and a human host? (Based on the real-life tongue-eating louse)

Evolutionary theorists have also used biology techniques to reconstruct language family trees using vocabulary “genes.” (Just like we talked about with the reconstruction of Proto-Indo-European.)

Using statistics, they were able to figure out that 10-30% of all words emerged during language splitting events – i.e. word “speciation” occurs in bursts of change, not gradually. This mirrors what we observe in biological evolution: about 22% of all genetic differences arise from bursts of sudden change.

Perhaps these “word explosion” events may reflect groups of people trying to establish a unique identity through their own distinct language. Kinda like those kids in primary school who thought they were so cool and different speaking Gibberish.

One Last Thing

If we take a step back and look at all these cool language evolution-y things, we can see how diverse this field is: from neuroscience to linguistics to evolutionary biology to archaeology (and more).

We’ll continue exploring this cross-disciplinary complexity in posts to come. Keep checkin’ in for more rad yarns! (And more shitty illustrations.)
