Man and here I thought the English system was kinda screwy, where at first it's in base 12 and base 20 at the same time what with having special unique names for all digits up to twelve, and then thirteen through nineteen are also uniquely weird, then at twenty we decide "man fuck that" and then it's in base 10 until we repeat that pattern every 100, ie "one hundred seventeen." Or then we occasionally do stupid things like "seventeen hundred" instead of "one thousand seven hundred."
It just now hit me that "teenager" is an inherently English construct because that weird partial second decade we have. I'm curious, how does that work in languages? Like, in French they have special words up to 16 and only do "ten-seven, ten-eight, ten-nine." You spend seven years as a teenager in England but only three in France.
In Hungary we don't even have a separate name for 11 and 12, just 10 + 1 and 10 + 2. But at least we messed up the billions, it's called 'milliárd' and the trillion is 'billió'. We were so close to making it perfect.
Seriously, have trouble enough with numbers anyhow. The French system is far more than my little brain can compute, so I pretend to have learned the language from Belgians.
But who knows, maybe the Danish system would have tipped my infant brain into having a better grasp of some concepts?
Actually in Estonian it's üheksakümmend kaks. The first being a compound word of nine(üheksa) and ten(kümme) while kaks is just two. So it would be 9+10+2.
Russian, Ukrainian, and Belarusian use fuck knows what word for 90. Almost every Slavic language uses „nine tens”. Eastern ones just went stupid and mushed „nine” and „hundred” into a paste.
There are two versions of its etymology:
it’s „nine tens”, except there’s no „tens” part and someone had a stroke… repeatedly
it’s „nine on the way to hundred” with no „on the way” part and with „in steps of ten” implied; oh and someone had a stroke… repeatedly
So we just roll with it.
PS: Do not ask about 40. There’s supposedly a reason for it, but we don’t really know either.
