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.
