We use questions to ask people for information (who’s there?), but we can also use them to make a polite request (could you pass me that?), to confirm social understanding (what a game, eh), and for stylistic effect, such as ironic or rhetorical questions (who knows!).  In this episode, your hosts Lauren Gawne and Gretchen McCulloch get enthusiastic about questions! We talk about question intonations from the classic rising pitch? to the British downstep (not a dance move...yet), and their...

Maps of languages of the world are fun to look at, but they’re also often suspiciously precise: a suspiciously round number of languages, like 7000, mapped to dots or coloured zones with suspiciously exact and un-overlapping locations. And yet, if you’ve ever eavesdropped on people on public transit, you know that any given location often plays host to many linguistic varieties at once. In this episode, your hosts Gretchen McCulloch and Lauren Gawne get enthusiastic about the complications...

What’s the “it’s” in “it’s three pm and hot”? How do you write a cough in the International Phonetic Alphabet? Who is the person most likely to speak similarly to a randomly-selected North American English speaker? In this episode, your hosts Gretchen McCulloch and Lauren Gawne get enthusiastic about absurd hypothetical linguistic questions with special guest Randall Munroe, creator of the webcomic xkcd and author of What If? 2: Additional Serious Scientific Answers to Absurd Hypothetical...

Partway down your throat are two flaps of muscle. When you breathe normally, you pull the flaps away to the sides, and air comes out silently. But if you stretch the flaps across the opening of your throat while pushing air up through, you can make them vibrate in the breeze and produce all sorts of sounds -- sort of like the mucousy reed of a giant meat clarinet. (You’re welcome.) In this episode, your hosts Lauren Gawne and Gretchen McCulloch get enthusiastic about the vocal folds!...

Your brain is where language - and all of your other thinking - happens. In order to figure out how language fits in among all of the other things you do with your brain, we can put people in fancy brain scanning machines and then create very controlled setups where exactly one thing is different. For example, comparing looking at words versus nonwords (of the same length, on the same background) or listening to audio clips of a language you do speak vs a language you don’t speak. In this...

Sometimes, we use language to make definite statements about how the world is. Other times, we get more hypothetical, and talk about how things could be. What can happen. What may occur. What might be the case. What will happen (or would, if only we should have known!) What we must and shall end up with. In other words, we use a part of language known as modals and modality! In this episode, your hosts Lauren Gawne and Gretchen McCulloch get enthusiastic about modals! We talk about the...

When societies of humans come into contact, they’ll often pick up words from each other. When this is happening actively in the minds of multilingual people, it gets called codeswitching; when it happened long before anyone alive can remember, it’s more likely to get called etymology. But either way, this whole spectrum is a kind of borrowing. In this episode, your hosts Gretchen McCulloch and Lauren Gawne get enthusiastic about borrowing and loanwords. There are lots of different...

The Rosetta Stone is famous as an inscription that let us read Egyptian hieroglyphs again, but it was created in the first place as part of a long history of signage as performative multilingualism in public places. Choosing between languages is both very personal but it’s not only personal -- it’s also a reflection of the way that the societies we live in constrain our choices. In this episode, your hosts Lauren Gawne and Gretchen McCulloch get enthusiastic about language policy and how...

Let’s say we have the set of words “Lauren”, “Gretchen”, and “visits” and we want to make them into a sentence. The way that we combine these words is going to have a big effect on who’s packing their bags and who’s sitting at home with the kettle on. In English, our two sentences look like “Gretchen visits Lauren” and “Lauren visits Gretchen” -- but that’s not the only word order that’s possible. In theory, we could also use other orders, like “Lauren Gretchen visits” or “Visits Gretchen...

It was the best of times, it was the worst of times. The pen is mightier than the sword. Knowledge is power, France is bacon. These, ahem, classic quotes all have something linguistically interesting in common: they’re all formed around a particular use of the verb “be” known as a copula. In this episode, your hosts Lauren Gawne and Gretchen McCulloch get enthusiastic about copulas! This is a special name for a way of grammatically linking two concepts together that’s linguistically special...

If you hear someone saying /sss/ and /fff/, it’s hard to hear those as anything other than, well, S and F. This is very convenient for understanding language, but it’s less convenient for analyzing it -- if you’re trying to figure out exactly what makes two s-like sounds different, it would be helpful if you could kinda sorta turn the language processing part of your brain off for a sec and just process them as sounds. In this episode, your hosts Lauren Gawne and Gretchen McCulloch get...

When you look at a series of words that sorta sound like each other, such as pesto, paste, and pasta, it’s easy to start wondering if they might have originated with a common root word. Etymologists take these hunches and painstakingly track them down through the historical record to find out which ones are true and which ones aren’t -- in this case, that paste and pasta have a common ancestor, but pesto comes from somewhere else. In this episode, your hosts Gretchen McCulloch and Lauren...

We can plot the words we use to describe temperature on a scale: cold, cool, warm, hot. It’s not as precise as a temperature scale like Celsius or Fahrenheit, but we all generally agree on where these words sit in relation to each other. We can also do the same with other sets of words that don’t necessarily have an equivalent scientific scale, such as the relationship between “some", "a few" and “many“ or even words like "suppose”, “believe” and “know”. In this episode, your hosts Gretchen...

If you want to know what a particular person, era, or society thinks about a given topic, you might want to read what that person or people have written about it. Which would be fine if your topic and people are very specific, but what if you’ve got, say, “everything published in English between 1800 and 2000″ and you’re trying to figure out how the use of a particular word (say, “the”) has been changing? In that case, you might want to turn to some of the text analysis tools of corpus...

Here’s a completely normal and unremarkable sentence. Let’s imagine we have two different coloured pens, and we’re going to circle the words in red and the affixes, that’s prefixes and suffixes, in blue. “Later today, I’ll know if I hafta get some prizes for Helen of Troy’s competition, or if it isn’t necessary.” Some of these are pretty straightforward. “Some”? Word. The -s on “prizes”? Affix. But some of them, “I’ll”, “hafta”, “Helen of Troy’s”, “isn’t”....hmmm. In this episode,...

Let's say I show you and our friend Gavagai a box of chocolates, and then Gav leaves the room, and I show you that the box actually contains coloured pencils. (Big letdown, sorry.) When Gav comes back in the room a minute later, and we've closed the box again, what are they going to think is in the box? In this episode, your hosts Gretchen McCulloch and Lauren Gawne get enthusiastic about Theory of Mind -- our ability to keep track of what other people are thinking, even when it's different...

What do the sounds fffff, vvvv, ssss, and zzzz all have in common? They're all produced by creating a sort of friction in your mouth when you constrict two parts against each other, whether that's your lips, your teeth, your tongue, the roof of your mouth, or in your throat. This whole class of sounds that are produced using friction are known as fricatives! In this episode, your hosts Gretchen McCulloch and Lauren Gawne get enthusiastic about fricatives! We take you on a tour from the...

When you see something on social media in a language you don’t read, it’s really handy to have a quick and good-enough “click to translate” option. But despite the fact that 2000 of the world’s languages are African, machine translation and other language tech tools don’t yet exist for most of them. In this episode, your host Gretchen McCulloch interviews Jade Abbott and Bonaventure Dossou of Masakhane, a grassroots organisation whose mission is to strengthen and spur Natural Language...

“I don’t have a pet dinosaur.” This sentence is, we assume, true for everyone listening to this episode (if it isn’t, uh, tell us your ways?). And yet it has a different feel to it than a more ordinary sentence like “I don’t have a cat”, the type of negated sentence that’s true for some people and not others. In this episode, your hosts Lauren Gawne and Gretchen McCulloch get enthusiastic about negation! We talk about how languages make sentences negative, how negation fits into the social...

The letter R is just one symbol, but it can represent a whole family of sounds. In various languages, R can be made in various places, from the tip of your tongue to the back of your throat, and in various ways, from repeatedly trilling a small fleshy part against the rest of your mouth to an almost fully open mouth that’s practically a vowel. In this episode, your hosts Lauren Gawne and Gretchen McCulloch get enthusiastic about R and R-like sounds, technically known as rhotics, including...

If you go to the linguistics section of a big library, you may find some shelves containing thick, dusty grammars of various languages. But grammars, like dictionaries, don’t just appear out of nowhere -- they’re made by people, and those people bring their own interests and priorities to the process. In this episode, your hosts Lauren Gawne and Gretchen McCulloch get enthusiastic about the process of figuring out the structure of a language and writing it down -- making a kind of book...

When we tell you, “stay lingthusiastic!” at the end of every episode, we’re using a grammatical feature known as the imperative. But although it might be amusing to imagine ancient Roman emperors getting enthusiastic about linguistics, unlike Caesar we don’t actually have the ability to enforce this command. So although “stay lingthusiastic!” has the form of the imperative, it really has more the effect of a wish or a hope. In this episode, your hosts Gretchen McCulloch and Lauren Gawne get...

There’s no known human society without language, whether spoken or signed or both, but writing is a different story. Writing is a technology that has only been invented from scratch a handful of times: in ancient Sumeria (where it may have spread to ancient Egypt or been invented separately there), in ancient China, and in ancient Mesoamerica. Far more often, the idea of writing spreads through contact between one culture and its neighbours, even though the shape of the written characters and...

“Cold enough for ya?” “Nice weather for ducks.” Small talk is a valuable piece of our social interactions -- it can be a way of having a momentary exchange with someone you don’t know very well or a bridge into getting to know someone better by figuring out which deeper conversational topics might be of mutual interest. In this episode of Lingthusiasm, your hosts Lauren Gawne and Gretchen McCulloch get enthusiastic about the science behind small talk: how we pick topics for small talk...

“Blick” is not a word of English. But it sounds like it could be, if someone told you a meaning for it. “Bnick” contains English sounds, but somehow it doesn’t feel very likely as an English word. “Lbick” and “Nbick” seem even less likely. What’s going on? In this episode, your hosts Lauren Gawne and Gretchen McCulloch get enthusiastic about the underlying pattern behind how sounds fit together in various languages, what linguists call sonority. We can place sounds in a line -- or along the...
