The Land Between Numbers and Letters

Next episode (on March 12th) will be the 2nd last episode of Grade -1, and will be my unique version of a "final exam" (it will be a fun video even for people who hate tests). If anybody wants to "study" for the exam, you can rewatch older episodes on this channel. After that, later in March, will be a long Grade -1 finale...

Malay speaker here! Alright to start off, let’s just list 0 and the first 10 numbers in Malay Sifar Satu Dua Tiga Empat Lima Enam Tujuh Lapan Sembilan Sepuluh If look carefully, you’ll notice that there is no numbers that is spelt with the same number of letters as it is trying to represent. If we played the letter number chain game, we get loop of 5 to 4, but just like English, all other number will eventually get to 4.

[@ComboClass]

Interesting! A mini loop at a similar spot to English’s fixed point (four)

[@deltalima6703]

Sifar 0 messed it up methinks

[@erdmannelchen8829]

In German it is Null Eins Zwei Drei Vier Fünf Sechs Sieben Acht Neun Zehn As you can see most numbers from 0-10 have 4 letters in them. And since Sieben has six letters and Sechs has 5 letters, those would fall down to Fünf, which has four letters. And Vier has four letters.

[@quandaledingle2107]

turkish it is like this sıfır bir iki üç dört beş altı yedi sekiz dokuz on onbir if it is 5 letters it goes to 3-2 loop (others except 3-2 since they are in loop) stuck on 4 also 0 seems similar to malay. 4 has 4 letters interesting why 4 is like that

[@Milanutje]

Here in The Netherlands we use the long scale, but instead of saying "a thousand [...]", we replace -on with -ard, so (translated): Million Milliard Billion Billiard Trillion Trilliard etc. This makes it kind of confusing at times to switch from using the long scale in Dutch to the short scale in English, just like how we use the decimal comma instead of decimal point. It would be much more convenient if all languages used the same number conventions.

J and k first appear in the quaternions, which ironically have no order. In German, ß (ss after short vowels or diphtongs) appears first in dreißig 30, but not in Switzerland. In Switzerland they learn Standard German (coll. "Hochdeutsch") in writing, but they abolished the ß for ss in the late 1990ies. The first German number alphabetically is acht 8.

In Norwegian, the chain of numbers always ends up at 2 (to), 3 (tre) or 4 (fire). In Finnish, the numbers up to 6 end up at 5 (viisi), but anything higher than that ends up in a loop between 8 (kahdeksan) and 9 (yhdeksän). The higher numbers can be quite long (the word for 17 has 15 letters, and the word for 27 has 22... Close but no banana)

"[..] but anything higher than [six] ends up in a loop between 8 (kahdeksan) and 9 (yhdeksän)." There are two exceptions: 100, "sata", and 1000, "tuhat". Those end up at 5. In Finnish we never say "one hundred" or "one thousand", it's always "(a) hundred" or "(a) thousand". (We also don't use articles with nouns. But we use a ton of inflection suffixes to counter. :) )

Since there are an odd number of integers from 1 to 9, not all of them can have a partner different from themselves. the map 1 ↦ 9, 9 ↦ 1, 2 ↦ 8, 8 ↦ 2 , 3 ↦ 7, 7 ↦ 3, 4 ↦ 6, 6 ↦ 4, 5 ↦ 5 is the map x ↦ 10−x, and since 5 is a fixed point of this map you can say that 5 partners with itself

In Portuguese (at least Brazilian Portuguese), recursive number spelling of letter count leads to two repeating cycles: either 6 and 4 ("seis" e "quatro", as "seis" has "quatro", 4 letters, while "quatro" has "seis", 6 letters), or 5 (as "cinco", five, has five letters). Edit: this Portuguese trivia was already mentioned at the comments.

[@Dr._Geno]

I love french because the french word for four: Quatre works as either 1 or 2 sylables either "cat" or "cat-re" then it goes back to purly 1 syllable until fourteen "quatorze" then back to one syllable untill seventeen "dix-sept" and stays at 2 syllables untill twenty where it goes back to 1 syllable for a number vingt then 21 is fun because it's 3 syllables for a number, same with 31, 51 and 61 with 41 being a 4 syllable outlier, then 70 is fun being litterally trasnlated as sixty-and-eleven, then eighty is fun being directly translated as four twenties, and then ninety-one is really fun being, depending on how you pronounce quatre a 3-5 syllable number as it translates as EITHER "four twenties and eleven" OR "four twenties eleven" why? just why?, at least it's more obvious in some places that numbers past ten just mean ten plus x or times x with seventeen eightteen and nineteen being: tenseven, teneight, and tennine. and then everything I mentioned before like 80 being "4 20", and 90 being "4 20 and 10" then 97 is "4 20 10 7" followed by "4 20 10 8" and "4 20 10 9" all before going back to one syllable for one hundred, so a drop from 5 syllables to one syllable. I think french also uses the long scale so you get wonderfull words like litterally "nine-hundred-four-twenty-ten-seven-thousand-two-hundred-sixty-eleven-million"

In Hebrew: 0 - אפס (efes) 1 - אחד (echad) 2 - שניים (shnayim) 3 - שלוש (shalosh) 4 - ארבע (arba) 5 - חמש (chamesh) 6 - שש (shesh) 7 - שבע (sheva) 8 - שמונה (shmonah) 9 - תשע (tesha) 10 - עשר (eser) There are actually a lot of letter in the Hebrew alphabet that don't show up in the names of numbers - including ג (unless you count גוגל - googol), ז, כ, and צ. That's 4 out of only 22 letters! If you start at 1 instead of 0, the letter פ doesn't show up until אלף (elef) - one thousand, and ס doesn't show up until סקסטיליון - sextillion. Also, because Hebrew is a heavily gendered language, all adjectives including numbers have masculine and feminine forms. The masculine forms of 1 and 2 are considered "default" (like most words in Hebrew, but not the other numbers which are feminine for some reason 🤷), but if the feminine forms are considered instead, the letter ד would not appear until מיליארד - milliard (Israel uses the long scale. On the short scale, it wouldn't appear until קוודריליון - quadrillion!)

I invented my own system of counting which I use whenever I need to count. Each digit has a name with only one consonant and one vowel. The vowel can be placed either before or after, or flanking, the consonant. There are only two vowels, either pronounced , or pronounced . For every number name that features an there is one that features an . Six is , for instance, and seven is . You can let the vowel flank the consonant, so that becomes , . This is optional. Here are the numbers from one to ten: 1 nu; 2 du; 3 ti; 4 pu; 5 pi; 6 si; 7 su; 8 cu; 9 ni; 10 di. Eleven is dinu, that is ten+one; twelve didu etc. Twenty is dudi two tens. Dudi-du is twenty-two. Thirty is tidi etc. One hundred is expressed as nuki, pronounced , two hundred duki etc. is a single , pronounced as in ; so, one hundred & eight would be expressed as: nuki acu, or nuki azudi-cu. Zu is zero. This is pronounced Zoo. A thousand could be , as a reciprocal with , three, or it can be expressed as , ten hundred. A Zee, , is one ten-thousand. Nuzi dipu-ki apidi-pu is 11 thousand four hundred & fifty-four. Have fun.

Small correction, you don't *always* end up back at four. There are some loops which go back and forth between two numbers, because of the larger syllable numbers. Also, even before those loops were discovered, it was still an open question whether every number came back to four.

in Ojibwe using the double vowel system of writing: 1 - bezhik 2 - niizh 3 - nswi 4 - niiwin 5 - naanan 6 - ngodwaaswi 7 - niizhwaaswi 8 - nshwaaswi 9 - zhaangswi 10 - mdaaswi how to pronounce: 1. e is always a long vowel and sounds like the e in meh except said longer 2. zh is like sh except with a z 3. the n and m without vowels (as in nswi and mdaaswi): imagine there is an i before the n or m but don't say it. so the n would sound like the n in the word minute 4. the double vowels have slightly different pronunciations than the single vowels: for naanan, the aa would sound like a prolonged ah and the nan sounds more like nun. it's a quick little a that kind of sounds like a u. in some dialects, the single a is replaced with u. for niiwin, the ii sounds like the double e in knee and the i sounds like the i in winter 5. the pronunciation is sort of like German in that every syllable is spoken and like Japanese in that almost every consonant has a vowel. so, ngodwaaswi is said n-go-dwaa-swi i think that's it for pronunciation rules. since Ojibwemowin (a dialect of the Algonquin language) is somewhere around 15000+ years old, we didn't need super big numbers. the source i got the numbers from (www.languagesandnumbers.com/how-to-count-in-ojibwa/en/oji/) says numbers up to only 1999 have been named at least our number 1 is alphabetically first haha

As a child learning the numbers when visiting family in Sweden I always recited 1 as "en" (i.e. common gender), but as an adult it seems as though the canonical form when talking about the number in itself (rather than the indefinite article) seems to be "ett" (i.e. neuter gender). I'm curious about what conventions there are regarding that, if any. Is it something that has changed over time, I wonder? Or perhaps it was an idiosyncracy of the person teaching me the numbers.

It depends on whether a space has any alphabetical value (which is debatable in itself), but if it does have a value, should it come before A or maybe even after Z? Also, if you're counting the number of letters, you need to decide whether the space counts as a letter at all!

In Japanese, the words for numbers are as follows (ordered kanji/hiragana/Arabic numeral): Some clarification though; like in English, there are cases where the same number can be pronounced differently (like how 12 can be pronounced “twelve” or “dozen”). The spellings I’m using here are the ones you’ll see most often when expressing standard quantities like amounts, page numbers, years, etc.. It’s a whole rabbit hole of specifics (and don’t even get me STARTED on counters, hoo boy) Also, this list will only consider positive integers, for simplicity’s sake. Anyways… For your basic numbers, it’s like this: 一/いち/1 二/に/2 三/さん/3 四/よん/4 五/ご/5 六/ろく/6 七/なな/7 八/はち/8 九/きゅう/9 十/じゅう/10 百/ひゃく/100 千/せん/1000 Now, those are the ones I’ve encountered via my academic studies (aside from one other but that’ll come up in a moment). There’s more, and here’s where it gets interesting. In English, we organize high powers of 10 into names based on groups of 3 (thousand = 10^3, million = 10^6, billion = 10^9, etc.). Based on some quick research I did online, Japanese does it a bit differently. In that language, powers of 10 get names based on groups of 4. The names are as follows: 万/まん/10^4 億/おく/10^8 兆/ちょう/10^12 京/けい/10^16 垓/がい/10^20 嬢/じょう/10^28 溝/こう/10^32 澗/かん/10^36 正/せい/10^40 載/さい/10^44 極/ごく/10^48 I skipped 10^24 because it has 2 pronunciations and kanji and I can’t tell which one better describes the “pure” number like the rest of these do, so I’ll list them both. 𥝱/じょ/10^24 OR 秭/し/10^24 There’s more, but once you get to 10^52, the same word can be used to refer to different quantities. So for the sake of simplicity I’ll stop at 10^48. So what are some interesting things we can pull from this? Well, as it turns out, because of how it’s organized, both English and Japanese have unique words for (at least as far as my list contains) numbers of the form 10^12n where n is a positive integer (including 0 too!). Also, if you were to play the number -> letters in number -> number of letters game in Japanese, using hiragana as a base for letters as it’s roughly analogous to the English alphabet, a few interesting things occur. (Before we do that, though, let me explain how large numbers with lots of different digits are named. The way it works is for any given number, look at the non-zero digits and write the number name follows by its corresponding place value. So, for example; 251 is 二百五十一 in kanji and にひゃくごじゅういち in hiragana. 404 is 四百四 in kanji and よんひゃくよん in hiragana (notice that 0s aren’t written, similar to how we don’t include them in cases like 101’s “one-hundred one”). Some words, like 800 have unique pronunciations (for 800, it’s pronounced はっぴゃく as opposed to はちひゃく like you’d expect, even though the kanji is the same), but aside from these exceptions, the general rule applies to most numbers of this form. So, what interesting things do we see? Well… One, you notice that in terms of hiragana count, many of the numbers listed here contain no greater than 3 hiragana characters unless they are composed of multiple different digits. That means you are very likely to fall to 1, 2, or 3 eventually. And the ones that contain 3 will just to go 2 anyways. いち/1、さん/3、よん/4、ろく/6、なな/7、はち/8、せん/1000、and all the named high powers of 10 sans 10^12, 10^28, and the second spelling of 10^24 (which contain 3, 3, and 1 respectively) contain 2 hiragana characters and as such will immediately fall to に/2. However, since 2 only uses 1 hiragana character, 2 and 1 form a cycle. (Also, rather obviously, any 1 character number falls into that cycle). Two, there are no numbers in Japanese that contain the same number of hiragana characters as their value. For all the basic digits, 100, 1000, and high powers of 10, the number of hiragana characters is either 1, 2, or 3. For all numbers 4 or greater, that’s too small. 1 has 2 characters which is one too many, 2 has 1 character which is one too few, and 3 has 2 which is one too few. For all the other numbers, the ranges of characters they can contain are as follows, up to 9999. 11-99: 4-9 101-999: 4-15 1001-9999: 3-20 As you can see, the upper bound for characters count maximum compared to the number smallest number in the list separates at incredible speed. There’s a decently easy way to calculate the bounds. For the lower bound, for any n-digit number, take the base 10 logarithm of the number, round down to the nearest integer, and raise 10 to it. Whatever power of ten you get, find the corresponding word for it. Take the number of characters in the word and add 1. (I know there’s a less jargon-y way to explain it, but I find it hard to verbalize). The reason we add 1 is because the lowest you can go is the power of 10’s amount of characters plus another digit’s character, and both 2 and 5 contain one character, which is the smallest amount you can add. For each range, the smallest number that sits at the lower bound is as follows: 11-99: 12 (じゅうに、4 characters) 101-999: 102 (ひゃくに、4 characters) 1001-9999: 1002 (せんに、3 characters) For the upper bound, for any given n-digit number, you will always use the number of the form 10^(n+1) - 1, because 9 has the most characters out of all the 1 digit numbers, so this number will be an n-digit long string of 9s. This also means that numbers of these forms are the ONLY numbers that maximize hiragana count. The way you calculate it is like this: however many digits are in the number, multiply that by 3. Then add the amount of characters for each positional number. So, the numbers are as follows: 99: きゅうじゅうきゅう、9 characters. 999: きゅうひゃくきゅうじゅうきゅう、15 characters. 9999: きゅうせんきゅうひゃくきゅうじゅうきゅう、20 characters. More importantly, because every digit and positional number contains 3 characters at most, this means that every n-digit number will contain less than or equal to 6n-3 characters. (Which aligns with the data we manually showed). So, If n is number of digits, then 10^(n-1) is the quantity of the lowest number with that amount of digits, and 6n-3 is the absolute highest amount of hiragana characters an n-digit number can contain. Since quantity grows exponentially and character amount grows linearly, and both are constantly increasing, and the only intersection of the functions occurs at a value less than 2, that means there’s absolutely no chance for intersection beyond n = 2. This all means that any number with at least 2 digits will always have less hiragana characters than it’s amount. One small caveat though is that 6n-3 doesn’t remain the upper bound forever, because the way numbers are written after 10,000 are slightly different. But, in the grand scheme of things, it will still increase linearly, and the gap has gotten so wide to that point (a size of 9979) that any non-exponential additions to the hiragana count that adhere to how the numbers are written are basically irrelevant. So, ultimately, all of what we just discussed shows that no number in the infinite spectrum of natural numbers greater than 4 will ever contain the same amount of hiragana characters as it’s value because the value will be too high compared to character amount, and for the rest (1, 2, and 3), it’s pretty easy to show that there’s no number where value = character count, meaning those numbers don’t qualify. Therefore, there is no number in Japanese that contains the same amount of hiragana as its value, and all numbers eventually fall to the 1 -> 2 -> 1 -> … cycle. With that, I post my comment. I’m sure there’s more to this topic, but I’ve already written a lot of stuff and don’t particularly feel like writing more lol. Great video as always, Domotro!

Once I had a job at a local library where I had to check the alphabetical order of the books in the shelves. Multiple bands of e.g. a dictionary, say parts 1 to 6, had to be arranged in their appropriate alphabetical order. That felt extremely weird, as I was thinking of numbers in terms of their numerical value.

[@alexeton86]

In Russian also has interesting patterns with letters and numbers. But it will be difficult to explain all of them, since Russian uses the Cyrillic alphabet. For example, there are letter-number cycle with numbers 5-4-6, and in some cases it ends on number 3 or 11.

Eight billion eight should be third! After that not counting spaces as a character, you get eight billion eighteen and eight billion eighteen hundred, followed by 9999 entries, with eight billion eighteen thousand at 10005th place! (At least if I accounted for everything)

[@Hinotori_joj]

You said "not counting spaces" but thats something to look at. Computers will count spaces as coming between the end of the word and 'a'. So for example, a computer would say the following are in order: 'eight, eight hundred, eighteen', but not counting spaces would be 'eight, eighteen, eight hundred'. As you can see, this changes the order quite a bit.

In portuguese we get 2 roots: Our numbers from 0 to 10 are: 0= zero 1= um 2= dois 3= três 4= quatro 5= cinco 6= seis 7= sete 8= oito 9= nove 10= dez 5 has 5 letters, so it maps to itself: 5->5 4 has 6 letters and 6 has 4 letters, so: 46

[@ComboClass]

Interesting!

[@monkeybusiness673]

In German, the first number would be 8 (Acht). Since we do *always* spell some numbers including "und", it should be followed by 8 quadrillion if you don't count a blank space; because we have two similar words to describe thousands of a quantity of millions or above. A million is Million, but a billion is Milliarde. So "Billiarde" would be next, which is 10^15. So I think the order is 8; 8*10^15; every number in the 8-to-9 quadrillion range;....

[@stevenlubick2689]

[@Kayclau]

In Spanish, the number 1 is pronounced "Uno", which has 3 letters and 2 syllables. However, 1 has 3 genders and each is pronounced differently. "Uno" is male, "Una" for female and "Un" when it's neutral. Now, if you're in a hurry, you might just omit the U and say "N" for 1. The number 2 is "Dos", with 1 syllable and 3 letters. But in some regions, the final S has a mute pronunciation, so it'll sound like you're saying "Do". 3 is called "Tres". Same as 2, it can sound like "Tre" 4 is "Cuatro", but just like with 1, if you're in a hurry, you can omit a letter, I this case the final O, and keep the meaning. So it's "Cuat" 5's name is "Cinco", which thankfully has 5 letters. It can also be abbreviated as "Cin", but we're not gonna use that now. So, in Spanish, you could count and go "N, do, tre, cuat, cinco" and each numbers would have as many letters as the amount they represent if you only count the letters that are actually being pronounced. 6 sadly breaks the pattern, since it's pronounced "seis" and there's no way to turn that into 6 letters.

Fünf Sechs Sieben (smug bastard) Acht Neun Zehn Elf Zwölf Dreizehn... In Russian, they have a different wird for 1, depending on wether you go on counting (then it sounds like razz, dwa, tri,...) or not, then it sounds like Addin. In Latin and Italian, Spanish, French etc., 4 has many more letters, starting with q: quattro, quatorze, and their 7 behaves more like the rest.

God Russian numbers are weird. I remember learning the tens and was just totally stunned that they go from ending in цать for 20 and 30 and then suddenly 40 is сорок (which isn’t even related to the word for 4 at all). Immediately following, 50 and 60 end with десять (stress on last syllable) and then in 70 and 80 the stress goes to the second to last syllable for some reason. Finally, 90 just decided it wants to be really freaking weird and be девяносто

And means decimal, 100 and 3 = 100.3 when speaking.

@@deltalima6703 I've never heard that convention before - it must be an American thing. How common is it? Perhaps it derives from the fractional part of customary measurements (e.g. 2⅜″ being read as "two and three-eighths"); decimals are another kind of fraction, after all. In British English it's more correct to include the "and". Obviously as stated the video is specifically about American English, but I think it's worth pointing out that the idea that including "and" in numbers is informal or incorrect isn't universally true.

[@ComboClass]

I haven’t heard the decimal convention much either. Normally “and” is pretty common in casual speech in American English the same way it’s used in British English (and similar to how “a hundred” is casually said for “one hundred”) although it’s less technical/official to include it here. But yeah I made sure to clarify it was just modern American English here for reasons like that
