You think you’ve got numbers figured out, right? One, two, three. Easy. Then you try to count in Frisian and suddenly your brain feels like it’s doing gymnastics.
Frisian numbers follow a logic that makes perfect sense to Frisians and absolutely zero sense to everyone else. And once you see how they work, you’ll either think it’s brilliant or you’ll want to lie down.
Let’s start simple. One through ten? Pretty normal. Ien, twa, trije, fjouwer, fiif, seis, sân, acht, njoggen, tsien. Weird spelling, sure, but the pattern is familiar enough.
Then you hit eleven and things get interesting.
In English, we say “eleven” and “twelve” which are their own weird thing, then we switch to “thirteen, fourteen, fifteen” where we’re basically saying “three-ten, four-ten, five-ten.” Makes sense in a backwards kind of way.
Frisian does something similar but with a twist. Eleven is “alve” and twelve is “tolve” which are special cases. But thirteen? That’s “trettjin.” Literally “three-ten.” Fourteen is “fjirtjin.” Four-ten.
Here’s where it gets fun.
When you get to the twenties, Frisian pulls a move that’ll make you question everything. Twenty-one isn’t “twenty-one” like in English. It’s “ienentweintich.” One-and-twenty.
They put the single digit BEFORE the ten. Just like German and Dutch do.
So twenty-five is “fiifentweintich.” Five-and-twenty. Thirty-seven is “sânenderttich.” Seven-and-thirty. You’re always counting backwards from how English speakers think.
If you’re learning Frisian and you come from an English background, this takes some serious rewiring. You can’t just translate word by word. You have to flip the whole thing around in your head.
But wait, there’s more.
When Frisians write numbers as words, they stick them all together as one long word. No hyphens, no spaces, just one massive word-train that keeps going. “Achtentweintich” for twenty-eight. “Njoggenentritich” for thirty-nine.
And if you think that’s confusing, try doing math in Frisian.
Imagine someone telling you a phone number. In English, you hear “two, seven, five, nine” and you write it down in that order. In Frisian, they’re saying the ones before the tens, so you have to do this little mental shuffle before you write anything down.
Native Frisian speakers don’t even think about it. It’s automatic. But for learners? It’s like patting your head and rubbing your belly while hopping on one foot.
The really interesting part is why Frisian does this. It’s not random weirdness. It’s actually an old Germanic trait that English mostly lost.
Old English used to do the same thing. In Old English, twenty-one was “an and twentig.” One and twenty. English eventually flipped it around to put the tens first, probably because it’s slightly more logical when you’re writing numbers down left to right.
But Frisian kept the old way. So did German, Dutch, and most other Germanic languages. English is actually the odd one out here.
There’s a practical side to this that Frisian speakers will defend. When you say the ones digit first, you’re giving more specific information upfront. “Five-and-twenty” tells you immediately it’s a five-something before you get the context of twenty.
Does that make it better? That’s up for debate. But it definitely makes it distinctive.
For language learners, Frisian numbers become this weird mental workout that actually helps you think differently. You can’t just translate. You have to rebuild the number in your head using different architecture.
And once you get used to it? It starts to feel natural. Your brain adapts. You stop translating and start just knowing that “twa-en-fyftich” means fifty-two without having to think about it.
The counting system is also a reminder that Frisian isn’t just “funny-looking English” or “Dutch with different spelling.” It’s its own language with its own logic, its own history, and its own way of organizing the world.
Even something as basic as counting to ten becomes a little window into how Frisians think, how their language evolved, and how they’ve held onto patterns that other languages abandoned centuries ago.
So next time someone tells you Frisian is basically English, ask them to count to thirty-seven. Then watch their brain melt.
