In 1066, a foreign duke crossed the English Channel with an army – and within a generation, speaking your own native language could shut you out of your own country's courts, church, and government. That's not a metaphor. For roughly three hundred years afterwards, English was pushed to the margins of official life in England, edged out by a working partnership between Anglo-Norman French and Latin. This is what happened to English after 1066 and it's why so much of your vocabulary today sounds French.
I've touched on the outline of this story before in some of my videos – like William, the Conquest, the long linguistic interruption that followed. But the details underneath that outline are more interesting than the headline. So let's go a little deeper.
A conquest of people, not just a throne
When William of Normandy took the English crown at Hastings, he didn't simply install himself as a new king over an existing system. Over the years that followed, he dismantled the existing Anglo-Danish aristocracy and replaced it with his own Norman nobility – though this wasn't the instant swap it's sometimes made out to be. Much of the redistribution of English land was staggered and punitive, driven heavily by a series of English rebellions between 1068 and 1070, met by William with brutal, deliberate reprisals in the north of England. By the time the Domesday Book was compiled in 1086 – essentially a nationwide audit of who owned what – the picture was stark: England's land was now overwhelmingly in Norman hands.

It's easy to flatten "the Norman Conquest" into a single battle and a change of monarch. What actually happened was closer to a slow, forceful replacement of the governing class of a country – something that has few clean parallels in English history before or since.
Language followed land. English itself didn't go anywhere; it remained the language spoken in homes, markets, fields, and workshops by the overwhelming majority of the population. What it lost was official status. And what replaced it wasn't French alone. Officialdom split into two tiers: Anglo-Norman French became the language of the court, the aristocracy, and spoken legal proceedings, while Latin remained the dominant language of the church and most written bureaucratic record-keeping. English was squeezed out by that combination: a spoken and written establishment that, between them, covered almost every route to power, and left English as the language of nearly everyone, but the official language of almost no one.
The language that ate its conqueror's vocabulary
Here's where English does something unexpected: it doesn't dig in and stay "pure." Over the following centuries, it absorbs an extraordinary volume of French vocabulary – historians estimate somewhere in the range of ten thousand words entering English during this period, a huge proportion of which are still in everyday use today.
The most quoted illustration of this is the split between farmyard animals and the meat that ends up on the plate: cow and beef, pig and pork, sheep and mutton, calf and veal. It's a genuinely useful way to visualise the linguistic layering the Conquest left behind – older, Germanic-rooted English words for the living animal sitting alongside newer, French-derived words for the prepared food.
But the popular version of this story – that English peasants raised the animals while French-speaking lords only ever encountered them cooked – is a tidy narrative. However it's more folklore than documented social history. What we can say with confidence is the linguistic pattern itself: it's real, it's traceable, and it lines up with the broader flood of French vocabulary into English legal, culinary, artistic, and administrative language during this period. The class story is a helpful way to remember it – just don't mistake it for a strict, documented rule about who was permitted to eat what.
Beyond food, French reshaped huge swathes of English vocabulary around law, government, and refinement generally. Words like justice, parliament, and courtesy are all Norman-era imports still doing everyday work in modern English.
English claws its way back
By the 14th century, something had shifted. Norman and English families had spent generations intermarrying, and the sharp distinction between "Norman ruler" and "English subject" had begun to blur into something closer to a shared English identity. Language followed suit.
In 1362, Parliament passed the Pleading in England Act, requiring court cases to be pleaded – spoken – in English rather than French, on the grounds that too few people understood French well enough to follow proceedings against them. There's a wonderful irony buried in the historical record here: the statute itself, as written and enrolled by Parliament, survives in French. A law mandating the use of English was, itself, composed in the very language it was pushing out of the courtroom – about as neat a snapshot of how entrenched that linguistic divide had become as you could ask for. And it's worth noting this was about spoken pleadings specifically; written legal records continued to lean on Latin and French for some time afterward, so this wasn't a light switch flipping overnight so much as the first firm crack in a very long-standing wall.
Then, toward the end of that same century, Geoffrey Chaucer sat down and wrote The Canterbury Tales in Middle English – a sprawling, witty, structurally ambitious piece of literature that proved, in the most public way possible, that English could carry sophisticated storytelling. It wasn't the first literary use of Middle English, but it's the one that stuck in the historical memory, partly because it's quite good.
What I keep coming back to with this story is how counterintuitive the ending is. English didn't win this fight by staying the same and outlasting French and Latin. It won by changing – by quietly absorbing thousands of words from the very languages that had displaced it, and coming out the other side of three hundred years richer and stranger than it went in.
Modern English is like a merged document. Every time you choose beef over cow, or justice over some older word English never got the chance to develop, you're using a small piece of that eleventh-century upheaval without ever thinking about it. I like that – the idea that a language, much like a culture, doesn't have to stay fixed to survive. Sometimes it survives precisely because it doesn't.
