Portuguese

Portuguese has separate words for every number up to dozen three, and we can keep all of them up to a dozen.

  • 0: zero

  • 1: um

  • 2: dois

  • 3: três

  • 4: quatro

  • 5: cinco

  • 10: seis

  • 11: sete

  • 12: oito

  • 13: nove

  • 14: dez

  • 15: onze

  • 20: doze

we can handle numbers after that the same way Portuguese handles most numbers that aren't divisible by ten, using the word "e" for addition (and using the Portuguese word for dozen for numbers up to thirsy).

  • 21: dúzia e um

  • 22: dúzia e dois

  • 23: dúzia e três

  • 24: dúzia e quatro

  • 25: dúzia e cinco

also like in Spanish, multiples of ten usually end with -enta in Portuguese. the -ensa solution works here too.

  • 30: trinsa

  • 40: quarensa

  • 50: cinquensa

the Portuguese word for ten tens is "cem", and multiples of cem are formed with variants of the -centos suffix. the seximal equivalent of this is to turn "nif" (loaned as "nife") into a -nifes suffix.

  • 100: nife

  • 110: nife e seis

  • 200: dunifes

  • 300: trenifes

  • 400: quatronifes

  • 500: quinnifes

  • 1000: seis nife

  • 1100: seis nife e nife

  • 1200: seis nife e dunifes

finally, the -exian series can be loaned directly.

  • 1 0000: unexião

  • 1 0000 0000: biexião
