Obviously, a new & easy-to learn language has to have absolute regularity & simplicity for all its numbers.
The base numbers should be monosyllabic & very distinct, for instance:
nil - won - tuw - tri - for - fiv - six - set - okt - nin - ten
Next groups up could be:
hunda - mila - miliona - ?
All numbers should be pronounced from left to right, with no joining up, no hyphens, no plurals & no "and".
Big numbers are separated with a comma after thousands, millions etc.
The same comma is used in the alphabetical & numerical representations.
It introduces a clarifying pause in the spoken versions, as well as the obviously-necessary break in the written numbers.
Examples:
0 | nil |
1 | won |
2 | tuw |
3 | tri |
4 | for |
5 | fiv |
6 | six |
7 | set |
8 | okt |
9 | nin |
10 | ten |
11 | ten won |
12 | ten tuw |
20 | tuw ten |
21 | tuw ten won |
36 | tri ten six |
99 | nin ten nin |
100 | hunda |
101 | hunda won |
160 | hunda six ten |
199 | hunda nin ten nin |
200 | tuw hunda |
206 | tuw hunda six |
266 | tuw hunda six ten six |
999 | nin hunda nin ten nin |
1,000 | mila |
1,001 | mila, won |
1,234 | mila, tuw hunda tri ten for |
2,000 | tuw mila |
20,000 | tuw ten mila |
20,001 | tuw ten mila, won |
23,456 | tuw ten tri mila, for hunda fiv ten six |
234,567 | tuw hunda tri ten for mila, fiv hunda six ten set |
1,000,000 | miliona |
1,000,001 | miliona, won |
2,345,678 | tuw miliona, tri hunda for ten fiv mila, six hunda set ten okt |
I will cover very big & very small numbers, & ordinals, separately.
