→ Catalan: trilió

From tri- (“three”) + -illion, from million; i.e. a million million million.

six

Haitian Creole: sis

Louisiana Creole: sis

Mauritian Creole: sis

Inherited from Middle French six, from Old French sis, six, from Latin sex, from Proto-Indo-European *swéḱs.
The numbers six and dix (“ten”), as well as the pronoun tous (“all”), are remnants of the Old and Middle French pronunciation system where final -s or -x was silent before consonants, pronounced /z/ before vowels, and /s/ in pausa. The only change is that the pausal pronunciation is now invariably used when these words do not precede their referent.


million

→ Crimean Tatar: million

Louisiana Creole: milyon

→ Polish: milion, milon, milijon, milian (Middle Polish), miljon (pre-reform orthography (1936))

Inherited from Middle French million, from Italian milione.


quadrillion

Inherited from Middle French quadrillion, from quadri- (“four”) + -illion.


quatre-vingts

Louisiana Creole: katre-vin

From quatre (“four”) and vingt (“twenty”), both of which are derived from Latin. The vigesimal pattern of expressing 80 as 4×20, however, is of Celtic origin; see, for example, Welsh deugain (“forty”), trigain (“sixty”), pedwar ugain (“eighty”). (The Latin for 80 is octōgintā.).


douze

Louisiana Creole: douz

Inherited from Old French doze, from Latin duodecim.


treize

Louisiana Creole: trèz

Inherited from Middle French treize, from Old French treize, treze, from Latin trēdecim.

The h- was added in Middle French to avoid confusion with vit when the letters u and v were not distinguished; compare the same in huile, etc. That huit does not undergo initial liaison is in fact due to a general rule for numerals (compare un, onze), not to a historically aspirated onset.

The successive multiplication of 1 by 2, then, by 3, by 4, etc. up to and including the 50th character only, gives the following result: 30,414,093,201,713,378,043,612,608,166,064,768,844,377,641,568,960,512,000,000,000,000. Which is expressed by the following words, invented, for the most part, because of the insufficiency of known expressions: Thirty vigintillion, four hundred and fourteen novemdecillion, ninety-three octodecillion, two hundred and one septendecillion, seven hundred and thirteen sexdecillion, three hundred and seventy-eight quindecillion, forty-three quattuordecillion, six hundred and twelve tredecillion, six hundred and eight duodecillion, one hundred and sixty-six undecillion, sixty-four decillion, seven hundred sixty-eight nonillion, eight hundred and forty-four octillion, three hundred and seventy-seven septillion, six hundred and forty-one sextillion, five hundred and sixty-eight quintillion, nine hundred and sixty quadrillion, five hundred and twelve trillion.

Un Bavarois, M. Willy Koesteler, vient d’établir un très curieux travail scientifique, une carte murale, qui fut exposée à la Foire de Paris et qui montre le développement du chiffre 2, de la première à la 250ᵉ puissance.

[1932 May 27, L’Intransigeant, page 2 (Gallica, RetroNews), column 3:

A Bavarian, Mr. Willy Koesteler, has just established a very curious scientific work, a wall map, which was exhibited at the Paris Fair and which shows the development of the number 2, from the first to the 250th power. He arrived, moreover, at the concept of the figure 2 to the 500th power, expressed in numbers as follows: 3,273 quinvigintillion, 390,607 quattuorvigintillion, 896,141 trevigintillion, 870,013 duovigintillion, 189,696 unvigintillions, 827,599 vigintillion, 152,216 novemdecillion, 642,046 octodecillion, 43 thousand 064 septendecillion, 789.483 sexdecillion, 291.368 quindecillion, 96.133 quartuordecillion, 796.404 tredecillion, 674.554 duodecillion, 883.270 undecillion, 92.325 decillion, 904.157 nonillion, 150.8886 octillion, 684.127 septillion, 560.071 sextillion, 9.217 quintillion, 256.545 quadrillion, 885.393 trillion, 53.328 billion, 527 million, 589 thousand 376.

La plupart des dictionnaires s’arrêtent avant d’avoir atteint le dodécillion ou le trédécillion, mais rien n’empêche de concevoir, par exemple, le centillion (mot que j’avoue n’avoir encore jamais rencontré) qui, dans le système décimal chiffré, s’écrirait 1 suivi de 600 zéros…

1997, Alain Frontier, La grammaire du français [French Grammar], Belin, →ISBN, page 311:

Most dictionaries stop before having reached the trevigintillion or the quinvigintillion, but nothing prevents us from conceiving, for example, [10⁶⁰⁰] (a word that I admit I have never encountered yet) which, in the decimal system, would be written as 1 followed by 600 zeros…

L’univers observable contient environ 80 milliards de galaxies, soit 32 000 milliards de milliards d’étoiles (32 trilliards d’étoiles), soit 3 x 10⁷⁹ atomes d’hydrogène (32 trédécillions d’atomes).

2013, Didier Hallépée, À mes enfants [To My Children], les écrivains de Fondcombe, →ISBN, page 226:

The observable universe contains about 80 billion galaxies, or 32 000 quadrillion quadrillion stars (32 sextillion stars), or 3 x 10⁷⁹ hydrogen atoms (32 quinvigintillion atoms).

Calculating the total number of protons and electrons making up regular atomic matter, one comes up with 1 followed by 80 zeros, or 100 thousand trillion sextillion sextillion sextillion atoms! This is equivalent to 25 million sextillion Earths.

Et le nombre de particules élémentaires contenues dans l’ensemble de l’Univers visible depuis la Terre, toutes étoiles et galaxies lointaines confondues, est estimé à cent trédécillions, c’est-à-dire 10⁸⁰ !

Voici encore un fait amusant : si vous battez minutieusement un jeu de cartes, l’ordre des cartes qui en résulte n’a jamais été vu auparavant dans l’histoire de l’univers. « Factoriel 52 » est un nombre très grand : 8 065 fois 10⁶⁷, soit plus de 80 undécillions de combinaisons possibles.

But if the mere surface of the Earth eludes the grasp of the imagination, what are we to think of its cubical contents? it embraces a mass of matter equal in weight to at least 2 sextillions, 200 quintillions of tons.

1864, Edgar [Allan] Poe, translated by Charles Baudelaire, Eureka [Eureka], Paris: Michel Lévy, frères, […], page 186:

But if the mere surface of the Earth eludes the grasp of our imagination, what are we to think of its cubic capacity? It embraces a mass of matter equivalent at least to a weight of two undecillion and two hundred nonillion tons.

Un rhétoricien aura beau vous affirmer que cette somme serait si énorme que tous les wagons de tous les chemins de fer du monde ne pourraient pas la porter, il aurait beau vous dire que les Alpes et les Pyrénées, fussent-elles des mines de diamant, ne représenteraient pas sa valeur, si un calculateur constate qu’elle ne peut s’écrire que par la rangée suivante de 39 chiffres : 342 653 248 699 000 000 000 000 000 000 000 000 000 ou, en nombre rond : 342 undécillions 653 décillions de francs, nous tombons absolument abasourdis sous le coup d’un pareil nombre ! […] La population des cieux ne nous conduit pas encore à des undécillions !

1880, Camille Flammarion, Astronomie populaire : Description générale du ciel [Popular Astronomy: General Description of the Sky], Paris: C. Marpon et [and] E. Flammarion, […], page 726:

A rhetorician will tell you that this sum would be so enormous that all the wagons of all the railways in the world could not carry it, he would tell you that the Alps and the Pyrenees, were they diamond mines, would not represent its value, if a calculator finds that it can only be written by the following row of 39 digits: 342 653 248 699 000 000 000 000 000 000 000 000 000 or, in round numbers: 342 undecillion 653 decillion francs, we are absolutely stunned by such a number! […] The population of the heavens does not yet lead us to undecillions!

Ce nombre prodigieux, qui met au défi toutes nos forces intellectuelles, qui confond même notre imagination, est le suivant: 416.496.400.000.000.000.000.000.000.000.000.000.000, et il s’énonce : 446 undécillions 496 décillions 400 nonillions.
