## 🆕 New from Linguistic Discovery

*This week’s content from Linguistic Discovery.*

### 🐹 *ham(p)ster*

I went to spell *hamster* this week and it’s been so long since I had to write the word that I completely forgot it *doesn’t* have a ⟨p⟩ in it! And then of course that got me to thinking about epenthetic consonants. Here’s a brief thread I wrote on it:

![](https://substackcdn.com/image/fetch/$s_!xtQl!,w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F45674d0a-3711-4272-a340-99a6befde37c_563x164.png)

> *hampster* is an example of what linguists call **epenthesis**, when a sound is inserted into a word. When you do it with consonants specifically it’s called **excrescence** (horrible name, I know).  
>  
> Another example is pronouncing *something* as *sumpthing*.  
>  
> Sometimes the epenthetic sound becomes permanent and the pronunciation of the word changes:  
>  
> *tremble* comes from Latin *tremulāre*, but notice how English has a ⟨b⟩ and the Latin doesn’t. That ⟨b⟩ was added in Old French.

Another example someone gave me in the comments which I had never realized is the surname *Thompson*, which etymologically is ‘Thomas’ son’, but with an intrusive /p/.

A new study finds that certain dogs are “gifted word learners”, and can apply the name of a category of toy to a new toy that shares the same purpose, even though the dog has never heard the name used for the new toy before.

A mother reads to her newborn son. Premature infants who heard recordings of their mothers’ voices showed more advanced brain development. Todd Holland

Premature babies who heard recordings of their mothers reading to them had more mature white matter in a key language area of the brain, a Stanford Medicine-led study found.

During the study, hospitalized premature babies regularly heard recordings of their mothers reading to them. At the end of the study, MRI brain scans showed that a key language pathway was more mature than that of preemies in a control group who did not hear the recordings. It is the first randomized controlled trial of such an intervention in early development.

### Birds all over the world use the same sound to warn of threats

An angry Australian Superb Fairy-wren confronting a Horsfield’s bronze-cuckoo. [David Ongley](https://macaulaylibrary.org/asset/281503311?ref=linguisticdiscovery.com)

At some point in the evolution of human language, our species transitioned from instinctual vocalizations to ones that had to be learned and passed down through culture rather than genetics.

A new study finds a bird call that appears to be a mix of instinct and learning: over 20 species of birds from around the world, separated by 50 million years of evolution, using the same call when they see a brood parasite (birds that trick other species into raising their young).

But while birds that have never seen a brood parasite know how to respond to this call, they don’t know how to produce it. They only do it after watching others produce it when a brood parasite is nearby.

So while the response to the call is instinctive, producing the call itself is learned behavior—representing a midpoint between instinctive and learned vocalizations.

  - I’d also like to point out that this article includes a really cool visualization (using a JavaScript library called D3) of the branches of the Indo-European language family, which allows you to hover over individual branches to inspect them more clearly. (Having a background in JavaScript myself, I may have to start using D3 for family tree visualizations like this. I had never thought of this use case.)

## 👋🏼 Til next week!

### Chicago’s hidden etymologies

Here’s one for my fellow Chicagoans and Chicago-lovers, from [Adam Aleksic](https://open.substack.com/users/193395523-adam-aleksic?utm%5Fsource=mentions) (@EtymologyNerd):

[![](https://substackcdn.com/image/fetch/$s_!SC8C!,w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F478ea0dd-94b9-4cc3-a5d3-6f9bf654647a_540x590.png)](https://www.instagram.com/p/Bix89vuFTAL/?utm%5Fsource=ig%5Fembed&ig%5Frid=9e35cb2d-5eba-422c-b84a-9df4cb51fb6a)

Adam doesn’t mention it in the infographic, but the word *Chicago* may be distantly related to the word *skunk*, both coming from an Algonquian root meaning ‘smell bad’. The original name for Chicago was either from the Fox language, *sheka:ko:heki* ‘place of the wild onion’ or from the Ojibwe language, *shika:konk* ‘at the skunk place’. Both ‘onion’ and ‘skunk’ would have been based on that root meaning ‘smell bad’.
