Why do you think 11 isn’t pronounced onety-one?

The first twelve numbers have unique names, but 13 was viewed as an unlucky number. Many were superstitious. Imagine if you had to memorize a billion names. Obviously, unique names had to stop at some point.

Many things ended with 12. Maybe it's because we live on Earth, and there are 12 hours in a day, 12 months in a year, and 12 zodiac signs. We even have a dozen eggs ...

If you are wondering why 11 or 12 were named the way they were, well, it was probably done the same way we name a child. It was done with lots of thought put into the name, especially a child's name ... to make it easy for the child to write out their name and for others to remember it.

But if you search the web or let an AI do it for you you might get a more academic answer.
oh myyy xD it makes sense.. i’ll use that irl soo good :)
Well as a native Spanish speaker I can tell you're not alone :)

It appears likely to be a relic from the use of a base-twenty system in the past, which is one of the few systems humans used historically. And that system may indeed have come from early humans thinking of fingers plus toes when counting.

Why they used base 60 is a bit of a mystery -- although base 60 does have some advantages: many divisors for the base. But it creates very unwieldy multiplication tables.

chill its just a random chess forum you didn't have to type a 5-page essay
I suspect my post could fit on a single page, @ThatRandomPerson111, but I could be mistaken, no doubt.

I was tempted to write more, but a little math history goes a long way, I think.

Thanks to @Dukedog in his #17 for providing a still more interesting and detailed explanation about the apparently connected origins of 11 and 12.

I had a friend who jokingly refereed to her eleven year old daughter as being oneteen, because she was already acting as a teenager.

you are on to something. the reason many things are divided by 12 is, because 12 is a small number yet has many divisors. so people could easily calculate, take 1/2, 1/3, 1/4, ... out of 12. same with 60, someone already pointed out sumerians/babylonians used, its 12*5. one more divisor. and because of this 12-base, they counted like 1..12 and gave 11 and 12 a special word. so, its all because of wisdom, simplicity and beauty.
