## Ndom

of the languages that natively use seximal, Ndom's numbering system is the most well documented. spoken by around a thousand people on Yos Sudarso island, Ndom is the reason this system uses "nif" for six times six.

numbers up to six have separate names.

1: sas

2: thef

3: ithin

4: thonith

5: meregh

10: mer

for numbers larger than six, the ones are separated from the sixes with "abo", which means "and".

11: mer abo sas

12: mer abo thef

13: mer abo ithin

14: mer abo thonith

15: mer abo meregh

twelve is just called "mer an thef", for two sixes.

20: mer an thef

21: mer an thef abo sas

22: mer an thef abo thef

23: mer an thef abo ithin

24: mer an thef abo thonith

25: mer an thef abo meregh

thirsy is called the very good name "tondor".

30: tondor

31: tondor abo sas

32: tondor abo thef

33: tondor abo ithin

34: tondor abo thonith

35: tondor abo meregh

40: tondor abo mer

41: tondor abo mer abo sas

42: tondor abo mer abo thef

43: tondor abo mer abo ithin

44: tondor abo mer abo thonith

45: tondor abo mer abo meregh

50: tondor abo mer an thef

51: tondor abo mer an thef abo sas

52: tondor abo mer an thef abo thef

53: tondor abo mer an thef abo ithin

54: tondor abo mer an thef abo thonith

55: tondor abo mer an thef abo meregh

and, as has already been stated, the Ndom word for nif is "nif". interestingly, instead of "nif an thef", the word for two nif is just "nif thef".

100: nif

130: nif abo tondor

200: nif thef

unfortunately, I couldn't find any source that listed out Ndom numerals far enough to show how larger multiples of nif are handled.

other natural languages that use seximal, like the Yam languages of Papua New Guinea, have well documented base root words, but how the roots connect together into numbers is unclear.
