Even worse. 90 in old Danish is "halvfemsindstyve" but it is rarely used today. The "sinds" part is derived from "sinde" means multiplied with but it is not in use in Danish anymore. That leaves halvfems, meaning half to the five (which is not used alone anymore) and tyve meaning twenty (as it still does).
We are in current Danish shortening it to halvfems which actually just means "half to the five" in old Danish (2.5) to say 90. 92 is then "tooghalvfems" (two and half to the five, or 2+2.5). The "sindstyve" part (multiplied with 20) fell out of favour.
So we at least have some rules to the madness. Were just not following them at all anymore.
TL;DW According to the perons, it's based on counting sheep and from base 20. 1 score = 20 sheep. 2 score = 40 sheep.
To get to 50, you have 2.5 score, but they don't say "two and a half". They are quite Germanic and say "halfway to 3" (Germans do this too). So, 50 = half three score.
The video also points out that English has (as the hodgepodge of a language it is) yet another remnant of Germanic languages: 13-19 are not "te(e)n-three to te(e)n-nine", but "three-te(e)n to nine-te(e)n", just like in German "drei-zehn bis neun-zehn".
It's quite easy to mock other languages, but there's always a reason for why things are the way they are. Think of Chesterton's fence.
I'm German and our way of counting is genuinely stupid. 121 would translate to "onehundred one and twenty". You'd think it's just a matter of practice but errors related to mixing up digits are statistically more common in German speaking regions. Awesome when it comes to stuff like calculating medication dosages and such. Like it's not a huge issue but it's such an unneccessary layer of confusion.
Norway used to count like the Germans, but switched after the introduction of the telephone. There were simply too many mistakes when telling the numbers to the operators, that a change was mandated.
Old people might still use the 2+90 variant though, but it is not very common.
French is pretty stupid too.
Smart Belgium with french as national tongue only changed that number aberration: They use the made-up word "octante" for eighty and "nonante" for ninety, instead of "quatre-ving" (four-twenty) or "quatre vingt dix" (four-twenty , ten) in proper french
I'm actually impressed by this map. The French speaking part of Switzerland is not only differentiated from the German speaking part, it is also differently coloured than France, since Swiss French has more sensible numbers.
Are the English numbers 11-20 influencer by the base 20 system of french back when we had French speaking royalty? And for some reason they're the only unique "digits" for lack of a better term that survived because once we get to twenty it's a pure base 10 system with a consistent pattern throughout.
I'm hoping someone more knowledgeable than me can tell me if my thinking is correct or not.
Edit: thanks for the history lessons, were interesting to read through.
They must have meant 9*10+2 for most of the countries. For French and Danish you would just remember the word for 90 instead of using logic to get there so they are actually quite 90+2.
The map is wrong, Czechs can do both 2+90 and 90+2, I am not sure if it's regional within the country, or depends on the context, but they definitely use both versions
Oh yeah, one of the pics that inspired me to study French. I was dreading the numerals but it's not that bad. You count tens and twenties and sometimes they're special. And numbers below 20 have specific names, but that's kinda true in most languages.
A lot of languages have weird corner cases. (Like, in Finnish most numbers are perfectly regular. Except 11-19 which are not "one-ten-and-x" but rather "x-of-the-second". I'm sure there's a reasonable etymological reason. At least they're not "teens".)
