English number words include numerals and various words derived from them.

Cardinal NumbersEdit

Cardinal numbers refer to the size of a group. In English, these words are numerals. The numbers from 0 through 9 have the same names as in decimal but numbers greater than 9, there is no agreed upon name for units.

  • 0 - zero (nought) (sometimes pronouced as "oh" in speech)
  • 1 - one
  • 2 - two
  • 3 - three
  • 4 - four
  • 5 - five
  • 6 - six
  • 7 - seven
  • 8 - eight
  • 9 - nine
  • X - ten, dek
  • E - eleven, el, elv, lev, ven
  • 10 - twelve, dozen, doh, zen, unqua
  • 20 - twenty
  • 30 - thirty
  • X0 - dekty
  • E0 - elty
  • 100 - hundred, gross
  • 1000 - thousand, great-gross

E has numerous names because eleven's (decimal name for E) etymology originates from a Germanic compound ainlif meaning "one left" thus, is a decimal name rather than a dozenal name. The word lev for E is not advised as lev is a root in SDN and would cause confusion e.g. levqua = 10;E but lev levqua could mean either 10;EE or E 10;E

For larger numbers, there are approximately X different systems. The following table show the following names for larger numbers:

The following text will use the Grand system, Ten for X, and Elv for E

In English, all numbers are perfectly regular, except for the word doh on its own can have no one in front of it (10 = doh / one-doh).

If a number is in the range 11; to EE;, and the second digit is not zero, you typically write the number in words separated by a hyphen.

20two-doh
21two-doh-one
32three-doh-two
79seven-doh-nine
EEelv-doh-elv

The grosans are written in the following fashion:

100one grosan
200two grosan
......
E00elv grosan

So too are the unands, with the number of unands followed by the word "unand"

1000one unand
2000two unand
......
E000elv unand
10 000doh unand
11 000 doh-one unand
87 000eight-doh-seven unand

For high powers of doh, the same conversion is used for biand, triand, quadrand, etc.

And example number such as 63E 014 791 62X; can be written in english as the following: six grosan three-doh-elv doh-four biand seven-grosan nine-doh-one unand six-grosan two-doh-ten

For long scale, "n" should be corresponding to 6n (106n) instead of 3n+3 (103n+3), and 6n+3 can be either "thousand n-illion" or "n-illiard". Besides, for super-long scale, "n" should be corresponding to 10n (1010n) instead of 3n+3 (103n+3), and 10n+3 is "thousand n-illion", 10n+6 is "n-illiard", 10n+9 is "thousand n-illiard".

The numbers < 109 (i.e. <= 9 digits) have the same names in all of these three scales.

The small units are "onety" (instead of "ten") for 101 and "hundred" for 102, besides, for super-long scale, 106 is still "million", but 1010 is a new word "unillion", and 1016 is "unilliard".

The googol family Edit

googol = 10^100

googolplex = 10^(10^100)

googolplexplex (googolduplex, googolplexian) = 10^(10^(10^100))

Also googoltriplex (=10^(10^(10^(10^100)))), googolquadriplex, googolquinplex, googolsextiplex, googolseptiplex, googoloctiplex, googolnoniplex, googoldekriplex, googolelpiplex, googoldoziplex, ..., googolcentiplex

Note: n-plex is 10n, n-minex is 10-n.

Table of dozenal numerals Edit

The value of “n-illion” is 103n+3 in short scale, 106n in long scale, and 1010n in super-long scale.

There is no consistent and widely accepted way to extend cardinals beyond centillion (centilliard).

(In this list, all numbers are written in dozenal)

Value English

(short scale, original)

every new term is 103 times as large as the previous term (n-illion is 103n+3)

English

(long scale, original)

every new term is 106 times as large as the previous term (n-illion is 106n)

English

(super-long scale, new)

every new term is 1010 times as large as the previous term (n-illion is 1010n)

Chemical elements with atomic number >= 9E Edit

Currently, all of the chemical elements with atomic number <= 9X have their names, for the IUPAC name of the chemical elements with atomic number >= 9E:

(symbol)

0 = nil (l)

1 = un (u)

2 = bi (b)

3 = tri (t)

4 = quad (d)

5 = quin (q)

6 = sex (s)

7 = sept (p)

8 = oct (o)

9 = nona (n)

X = dek (k)

E = el (e)

If the unit digit of the atomic number is 2, 3 or 9, then use “bium”, “trium” or “nonium” instead of “biium”, “triium” or “nonaium”.

For example, the 172nd element is “unseptbium”, and the symbol of it is “Upb”.
