Normal children usually gain fluency in their native language by age 5. Danish children need to wait until age 7.

It's kind of funny how aware Danes are of their weird numbers system. I speak Norwegian and whenever I'm in Denmark they use the more sensible Norwegian number system to explain to me the prices of stuff (probably because I give them the deer in the headlights-stare whenever I hear something like "fem og halvfjerds").

No kidding. It's the sort of thing that makes you think about how different people process info differently

TIL that there's actually (kinda but not really) a method to the madness that is our numbers 😄

In francophone Switzerland, they use septante, huitante, and nonante for 70, 80, and 90, respectively. Much more sensical, imo.

The other way around. We started with base 20 everywhere then simplified some of it.

During medieval times it used to be :
10 Dix (10)
20 Vingt (20)
30 Vingt et dix (20+10)
40 Deux-vingt (2x20)
50 Deux-vingt et dix (2x20+10)
60 Trois-vingt (3x20)
70 Trois-vingt et dix (3x20+10)
80 Quatre-vingt (4x20)
90 Quatre-vingt et dix (4x20+10)

Then they switched to base 10... But only up to 70 for some reasons in France. Belgium and Switzerland (and some parts of France) have gone all the way to 100 by using Septante (70), Octante or Huitante (80) and Nonante (90).

We're not that different with the teens. We effectively say "seven ten", "eight ten", "nine ten". You don't think of nineteen as "nine+ten", it's just its own number. Well, the French take that one step farther.

Agree. But you can say "C'est quoi ?" too. More "street language" but it's okay

French-Québec : “Kossé ça?”
French also : “C’est quoi?”
… or : “Qu’est-ce?”

Word for word of "qu’est-ce-que c’est ?” …
…goes like : "What’s this that this is?
…or : “What’s this which this is?”

“Qu’est-ce?” sounds like the english “Case”.
Since this is just one syllable it might be difficult to hear out of context.

In Portuguese we actually can say "O que é isso?", basically the same as in Spanish, but I'd say I use more commonly "O que que é isso?", which seems closer to French version. Funny, had never thought about it like that.

Although most French say "Qu'est-ce que c'est", it is worthy to note that the proper/formal French is "Qu'est-ce?". So strictly equivalent to "What is that", word for word. :)

was gonna say props to Switzerland and Belgium for having proper numbers :) idk why we don't switch

Why not use the existing septante, octante, neunante?

Well and German, and some other Latin languages, and a bit of Nordic/Slavic languages, and all the other languages whose pockets English rifled for loose vocabulary.

I love the language, honestly, I love how completely and unapologetically a clusterfuck it is, but it's a clusterfuck.

I want to tell you that no french think of it that way.

Of course not, that's the point though. It is your first language, so for you that's the norm. But for the rest of the world with another language that's weird as fuck.

There's only one place a French native gets this wound up about a joke. Are you Parisian?

It doesn't matter, it's just something every child learns by heart and doesn't question. You don't have to be offended by this post, it's just funny

Uh, French is my first language and I've definitely thought that four-twenty-ten-seven was a weird as fuck way to say ninety-seven since I was a kid.

nah, you guys are just weird.
