Medieval Latin from 500 to 1500
Medieval Latin was a living language that evolved significantly from its Classical roots through changes in pronunciation, grammar, and vocabulary. Listeners learn about Charlemagne's 789 AD script reforms, the introduction of Germanic words like werra, and how scholars like Thomas Aquinas invented new terminology. This transformation allowed Latin to remain the backbone of European law, religion, and daily life for a millennium.
In 789 AD, Charlemagne laid down the law with his Admonitio generalis, forcing monks to use Carolingian minuscule to make writing easier to read. Jack and Olivia track how the old Roman word for war, bellum, was given the flick for the Germanic werra, while Thomas Aquinas cooked up new terms like quidditas to handle Greek logic. This shift from the stiff Classical style turned Latin into a fair dinkum living language used for everything from high-stakes theology to the Archpoet’s rowdy pub anthems. The hardening of the 'V' sound and the use of unus as a starting word for nouns shows just how much the language evolved before it reached the modern era.

I always reckoned Latin just carked it once the Roman Empire went belly up. I thought those monks were just blindly copying words they didn't even get.
You're going to explain how Latin changed to keep the whole show on the road in medieval Europe. Welcome to PodThis and Learn With Me. I'm Jack and this is Olivia.
The Living Language: From Cicero to the Middle Ages
I've been wondering about something. After the Roman Empire bit the dust, did Latin just become a language for old blokes in dusty libraries?
Not even close. It was a fair dinkum living tool used for every part of life. They used it for heavy church business and for singing songs in the pub. Take a bloke known as the Archpoet back in the twelfth century. In his poem, the Confession of Golias, he wrote about wanting to die in a tavern with a drink in his hand. It shows the language was alive and kicking, not stuck in a museum.
That's a bit of a turn-up. I suppose I just assumed that because they were still using Latin, they were just copying the exact words Julius Caesar used.
That's a common mix-up, but it's not how it worked. If the old Roman words didn't do the job, they simply gave them the flick. For example, the Classical word for war was bellum, but it sounded too much like bellus, which meant pretty. To avoid the confusion, they pinched the Germanic word werra. That's the deadset ancestor of our modern word war. If you were a soldier back then, which word would you reckon is easier to understand in a scrap?
Definitely the one that doesn't sound like you're calling the battle pretty. So they were just making it up as they went along?
In a way, yeah. When Thomas Aquinas was flat out writing his Summa Theologica, he found the old Roman vocabulary didn't have the right gear for Greek logic. He ended up inventing brand new words like quidditas, or what-ness, to explain his ideas. It's a bit like how we had to invent words for the internet because the old ones didn't fit the tech. They were changing the actual shape of the words to keep up.
So it was basically evolving to stay useful.
Spot on. Even the way they wrote it down changed. In the year seven hundred and eighty-nine, Charlemagne put his foot down in a document called the Admonitio generalis. He forced monks to use what we call Carolingian minuscule. Before that, Latin was often just a wall of capital letters with no gaps. He gave us lowercase letters and proper spaces between words. We still use that same style at uni today. How do you think that changed things for a student trying to read a manuscript?
It probably saved them a massive headache. So if I've got the hang of this, Medieval Latin wasn't some frozen relic. It was a flexible language that people used for everything from high-level philosophy to bragging about being a bit of a boozer. But if the vocabulary was getting such a massive overhaul, what was happening to the actual nuts and bolts of the grammar?
That's the perfect spot to look at how the sounds and the structure started to shift.
Grammar Shifts and the Sound of Medieval Latin
We need to look at how the sounds and rules of Latin shifted during the Middle Ages. What do you reckon a priest in a cathedral sounded like compared to a Roman senator?
You'd think they would be much the same. If you are reading the same script, a priest doing the mass in a big stone cathedral should sound just like a senator giving a speech in the old Roman Forum.
That is the standard guess, but it is not how it went down. Linguistic historians say that if a Roman senator hopped in a time machine and heard a priest in the year one thousand and one hundred, he would not have a clue what the bloke was banging on about. The pronunciation had drifted too far from its roots.
So they were not even making the same sounds anymore?
Not even close. Take the word for heaven, written as C-A-E-L-U-M. By the eleventh century, or even earlier, the C had shifted from a hard K sound like ky-loom to a TS sound like tsay-loom. Linguists argue this proves the language was drifting away from its Roman origins.
That is a massive shift for just one letter.
It changed the music of the language. It was more than just the C. Julius Caesar would have said 'Weni, widi, wiki'. By the Middle Ages, that V had hardened into the V sound we use now. The Church's Latin sounded completely different to the gear heard in the Roman Forum.
It would sound much more like the modern languages we hear in Europe today.
Exactly. It was happening in the grammar too. They started using the word 'unus', which means one, as a way to say 'a' or 'an'. It is like taking an old Holden and swapping the original motor for a modern fuel-injected one. The body looks the same, but the way it runs is completely different. A language is a living thing that never stops changing.
So the way people spoke Latin in the Middle Ages would have been gibberish to an old Roman. The C and V sounds had changed too much. Plus, the grammar was starting to look like modern languages because they used 'unus' to mean 'a' or 'an' instead of just the number one.
That is the deadset truth of it. PodThis.
I used to reckon Medieval Latin was just a messy version of what the Romans spoke. I see now it was a living tool that changed to stay useful. Swapping bellum for werra shows they were simply making sure people didn't mistake a war for something pretty. Hearing how the C in caelum shifted to a ts sound makes it clear the language was moving with the people, even the blokes in the pub.
It was a practical language for a changing world. This week, have a squiz at any printed book and see if you can spot the lowercase letters and spaces that Charlemagne's monks first sorted out for us. Keep on learning and keep on growing. Good on you for listening to PodThis.
