Number names
This article is about the structure of number names and the naming of numbers in the decimal system .
The structure of number names
The example of the number four hundred twentyseven thousand five hundred thirty four (427,534) shows the graded structure of the number names. What is striking is the systematic reversal of the tens and units in the German language , which, for example, only occurs in English from 13 to 19.
Zero to nine
The values of the decimal digits are: zero , one , two , three , four , five , six , seven , eight , nine . The name zero always stands alone; The entire naming system is based on the other nine number names. Except for the seven, all of these numerals are monosyllabic.
ten
From the ancient Germanic word * tehun, which is related to ancient Greek deka (δεκα) and Latin decem , today's word ten has developed from ancient high German zehan .
Eleven and twelve as exceptions
Eleven and twelve from Gothic ainlif and twalif with the suffix lif (= "that goes beyond ") means one over and two over , i.e. one or two more than the ten.
These exceptions also exist in all other Germanic languages, for example English (eleven, twelve) or Dutch (elf, twaalf) . Here one notices the earlier approach for a number system based on twelve numbers. See also dozen (= 12), shock (five dozen = 60) and the bulk (twelve dozen = 144).
Thirteen to nineteen
In contrast to the numbers over twenty, in which the units and tens are combined with an “and” (seven and twenty), this is not the case with the numbers from thirteen to nineteen . For the numbers sixteen and seventeen , the units digit is pronounced and written in abbreviated form (“sixteen” instead of “sixteen” and “seventeen” instead of “seventeen”).
Twenty to ninety nine
Twenty : from Gothic twai tigjus (= "two ten units"), later twai tig. This form of formation continues up to ninety, whereby the final syllables of the six and the seven are partly shortened ("sixty" instead of "sixty" and "seventy" instead of "seventy"). An exception is the use of " thirty " (instead of "thirty"). The unit of units is named first ("twentyfive"). In the case of the one, this is shortened ("fortyone").
Other languages
In some languages remnants of a vigesimal system are still preserved: For example, in French (in France and Canada) this series is only built up to 60 according to this pattern. This is followed by "sixtyandten" (soixantedix), "fourtimestwenty" (quatrevingts) and "fourtimestwentyandten" (quatrevingtdix). In Belgian French, however, there are the numerals septante and nonante for 70 and 90, and in Swiss French there are also huitante and octante for 80. Danish uses the vigesimal system for numbers from 50 to 90; for example, 60 in Danish is tres (indstyve), i.e. H. "Threebytwenty", or 50, means halvtreds (indstyve), i.e. H. "Half threebytwenty" (for "2.5 × 20").
In contrast to the German language, in some other languages , such as Russian, Ukrainian, English, Swedish or French, the unit of ten comes first (e.g. twentyfive in English ). Other languages in which single and tens names are ranked as in German are Dutch, Danish, Luxembourgish, Slovenian and Arabic. Both variants are possible in Czech, i.e. H. “Twenty and One” or “Twenty One”; The same is true in Norwegian, where the order corresponding to German or Danish has been officially replaced by law by the order corresponding to English or Swedish, but is still common in the spoken language.
Hundreds
Hundred : from Gothic hunda and Latin centum. Originally only used as a plural word, that is, only from two hundred. The first hundred was completed in Middle High German by the numeral zehenzec / ic, zehent, zênzic ("ten"). Nowadays either the hundred or the simple hundred, i.e. one hundred, is used. To express a multiple of a hundred, a singledigit number is placed in front of the hundred . So the number name for three times a hundred is three hundred. If the multiple of a hundred is greater than 9, you switch to a thousand.
For the special number range from 1100 to 1999, actually already in the subsequent thousands, there are, however, the terms eleven hundred, twelve hundred to nineteen hundred in German  and similarly in various other languages  which are mainly used for years and occasionally in slang . In contrast to German, this is often continued in English up to numerical values of 9999.
Thousands
Thousand : from Gothic thusundi. In the IndoEuropean language area, no uniform designation has developed for numbers over one hundred. The root word “thousand” occurs only in the Germanic, Slavic and Baltic language areas, while in Romance the name is derived from Latin mille and in Greek from χιλιοι.
A million and a billion
Million : from Latin mille (= thousand) and one (enlarging suffix ); so actually "great thousand". The million is the square of the thousand.
The billion is the third power of a thousand or a thousand million.
Trillion, Billiards and Beyond
From a billion onwards, the illion and illion scheme is repeated . The prefixes are derived from Latin : Bi for 2 ( trillion and billiards ), Tri for 3, Quadri for 4, Quinti (also: Quinqui) for 5 and so on. So give powers to the Million: a bi llion is 1,000,000 ^{2} , a tri llion is 1,000,000 ^{3} , a Quadri llion is 1,000,000 ^{4} and so on. A quadrillion is a thousand trillion. The same scheme can be applied to trillions, quadrillions, and so on. This system is known as the Long Scale . It goes back to Nicolas Chuquet and Jaques Peletier du Mans .

Difference between Europe and the USA
Since the 17th century there have been two different conventions for names of large numbers above the million, which also use identical number names for completely different numbers. In practice, this often leads to misunderstandings:
 The original longscale system described in this article, attested since the 15th century, is the recognized reference system. The numbers from one million onwards are called million  billion  trillion  trillion  trillion … , whereby each number is 1000 times larger than the previous one.
 In the shortscale system , the trillion is only 1,000 times a million. Then 1000 times a trillion is the trillion and so on. The prefixes correspond to the powers of the number 1000, but the Latin meaning of the prefix is always 1 less than the power: a bi llion is 1000 ^{3} , a tri llion 1000 ^{4} . This system became common in some countries from the 17th century .
The longscale system was to be used consistently around the world at the suggestion of the 9th Conference of the Bureau International des Poids et Mesures in 1948. After France also switched from the shortscale system that had been in use until then, the longscale system was used throughout Europe for a short time. However, as a result of the influence of the USA and the international media, there is increasing deviation from it. Virtually all English speaking countries including the UK no longer use it; in Canada it is only used in the Frenchspeaking part, in South Africa only by Afrikaans speakers.
The shortscale system is officially used in the United States, but is now common in the rest of the Englishspeaking countries. It is also used in Puerto Rico, Brazil and Turkey, although the word milyar for billion (10 ^{9} ) is firmly anchored in Turkish usage . The British English has adapted the American language. In US English there are no names ending in arde (billion, billiard ...); they are rarely used in British English. More about the origin of this system can be found in the article Billion . Perhaps because of the possible misunderstandings, these large number names beyond the billion are also rather rare in everyday language in the Englishspeaking world, usually one prefers to use constructions like a thousand million millions.
Nomenclature for numbers from 1,000,000
Numerals with a value of 1,000,000 or more are named according to the system of Nicolas Chuquet according to Latin prefixes. The numerical word million is an exception . This is derived from the Latin mille (1000). The noncombination prefixes, i.e. prefixes that do not appear in combination with other prefixes (apart from the formation of prefixes with a value of over 999), are derived from Latin ordinal numbers. The combination prefixes are derived from Latin cardinal numbers.
One (noncombination prefixes):
1  mi
2  bi
3  tri
4  quadri
5  quinti
6  sexti
7  septi
8  octi
9  noniOne (combination prefixes):
1  un
2  duo
3  tre (s)
4  quattuor
5  quin
6  se (x)
7  septe (m) (n)
8  octo
9  nove (m) ( n)Tens:
10  (n) deci
20  (m) (s) viginti
30  (n) (s) triginta
40  (n) (s) quadraginta
50  (n) (s) quinquaginta
60  (n) sexaginta
70  (n) septuaginta
80  (m) (x) octoginta
90  nonagintaHundreds:
100  (n) (x) (s) zenti
200  (n) duzenti
300  (n) (s) trezenti
400  (n) (s) quadringenti
500  (n) (s) quingenti
600  ( n) seszenti
700  (n) septingenti
800  (m) (x) oktingenti
900  nongenti
The prefixes can be combined in this order : ones + tens + hundreds.
For example, if a tens or hundreds prefix is preceded by an M in brackets, this means that this M should be added to the units prefix when combined with a units prefix, in which this M in brackets is also included (the bracketed M in the tens or hundreds prefix is omitted).  This also applies to all other letters in brackets.
Examples:
 Tre s zenti
 Septe m oktogintacenti
 Se x centi
In order to create a numeric word from these prefixes, the ending llion must be added. The number formed corresponds to 10 ^{6n} (n stands for the value of the prefix formed; e.g. trescenti = 103). If you add the ending lliarde to the prefix (according to Jacques Peletier du Mans ), the number of zeros is 3 zeros larger than the number of zeros in the numerical word with the ending llion.
Example:
 Centillion = 10 ^{100⋅6} = 10 ^{600}
 Centillion = 10 ^{600 + 3}
If you use a tens prefix without combining it with a hundreds prefix, you have to replace the ending a (if available) with i.
Example:
 Triginta → triginti → Trigintillion (10 ^{30 * 6} = 10 ^{180} ).
From 6000 zeros
John Horton Conway and Allan Wechsler have proposed an extension of the above system to represent a number with 6000 and more zeros:
To form the number word with the value 10 ^{6000} ,
 the exponent is taken (6000),
 this is divided by 6 (1000),
 the quotient is divided into groups of three (1_000).
 "Mi" is the noncombination prefix for a single 1.
 "Lli" is the distance for the next group of three.
 “Ni” stands for thousands (as a placeholder; if it stands alone, then without a specific number).
 "Llion" is the ending so that the prefix becomes a number.
The numeral for 10 ^{6000} is therefore: Millinillion.

 Novemdezillion = Novendezillion
 Quinquillion = quintillion
According to Nicolas Chuquet's system , the following prefixes can be derived from (late) Latin numerals:
18  duodeviginti
19  undeviginti
28  duodetriginta
29  undetriginta
38  duodequadraginta
39  undequadraginta

Abbreviations
The following abbreviations are valid in the German language:
 Million = million
 Mill. = Million / millionaire
 Billion / Billion / Bill. = Billion
 Bio./Bill. = Trillion
 Brd./Bld. = Billiards
Compilation of the irregularities
 First the hundreds, then the ones and then the tens.
 The suffix “zig” is used  and as an exception “sig” for thirty  instead of “teen”.
 The number 10 means “ten” (instead of “only”).
 The number 11 means “eleven” (instead of “oneteen”).
 The number 12 means “twelve” (instead of “two”).
 The number 20 means "twenty" (instead of "two").
 In the case of a number composition with “one”, the “s” is generally deleted (example “one hundred”).
 In the case of a number composition with “six”, the “s” in the two special cases “sixteen” and “sixty” is deleted and the letter combination “ch” is not spoken like “k”, but with the ego sound .
 In the case of a number composition with “seven”, the “en” is deleted in the two special cases “seventeen” and “seventy”.
 Starting with the number 21, one and tens syllables are linked with “and” (example “twentyone”).
Fractions
Fractional numbers are formed with the ordinal numbers and the suffix –el (third, quarter, fifth, etc.).
The terms one (instead of whole ) and second (instead of half ) are often only used in mathematical expressions.
Fractional numbers as adjectives can also be substantiated. Example: two twos are equal to one.
Myriads and Myriads
The Myriad stands for a number of 10,000 (ancient Greek μυριάς  myriás), plus the length unit Myriameter = 10,000 m. The plural myriads , on the other hand, denotes an uncountable set (μύριοι  mýrioi: innumerable, infinitely many).
Zig
The colloquial expression "zig" describes a number which  hence the term originates  from the range of numbers ending in "... zig", i.e. twenty to ninetynine. The mostly spoken word suggests that the estimated number is subjectively perceived as high. Zig is more than about or a good dozen and less than close to a hundred.
At the beginning of the story of the famous trilogy The Lord of the Rings by the British writer JRR Tolkien , the hobbit Bilbo Baggins celebrates his fiftyfirst (111th) birthday.
Zillion
Due to numerical values that are no longer comprehensible , the word "zillion" was coined in English based on million, billion and probably also on number names such as decillion, undecillion, duodecillion etc., which is colloquially used for a huge but indefinite number and has no mathematical validity.
“Zillion” can be traced for the first time in 1944 with the journalist and writer Damon Runyan (1880–1946), but it can be found earlier with “Bazillion” (1939, NY Times), “Jillion” [ʤilljən] (1942) and “Squillion” (1943) ) similarly formed names for fictitious numbers of immeasurable sizes. Since then, the number of such English imaginary names, generally used jokingly or as jargon for large numbers, has increased greatly, even if none of these names has been as popular as “Zillion”. For example, there are now (in alphabetical order):
 bajillion, bazillion, bizillion, brazillion (to Brazil = Brazil), dillion, fantillion, gadzillion, gagillion, gajillion, gazillion, godzillion (to Godzilla ), grillion, hojillion, jillion, kabillion, kajillion, kazadillion, kazillion robillion, skillion, squidillion, squillion, trazillion, umptillion ( umpteen = "zig").
In German, however, these terms can only be found in translations of AngloSaxon sources. The Donald Duck translator for Erika Fuchs , however, has Dagobert Ducks assets of 607 Tilli Onen, 386 zillion etc. and from 5 multiplujillion, impossibidillion 9, 7 fantasticatrillion and from 5 trillion quintiplitillion unptuplatillion multuplatillion impossibidillion fantasticatrillion dollars converted and with its neologisms of Fanta Tilli Arden , Fantastillions and Pimpillions reproduced.
Fictitious figures were placed in an original system, including by zoogol and gazoogol (new creations based on the the nineyear mathematician nephew Milton Sirotta coined in 1938 " googol "  so one with 100 zeros) from the FrancoAmerican " pataphysicist " André Joyce in presentation by Michael Joseph Halm .
An allusion to the zillions is the album How to Be a… Zillionaire! from group ABC .
