Spanish

Spanish has unique names for every number up to dozen three, which is halfway between two multiples of ten. the seximal equivalent of this is to have unique words for everything up to nine before things get more systemic.

  • 0: cero

  • 1: uno

  • 2: dos

  • 3: tres

  • 4: cuatro

  • 5: cinco

  • 10: seis

  • 11: siete

  • 12: ocho

  • 13: nueve

we can handle the next two numbers the same way Spanish handles most numbers that aren't divisible by ten, using the word "y" for addition.

  • 14: seis y cuatro

  • 15: seis y cinco

most Spanish names for multiples of ten end with -enta. a good seximal equivalent would be something like -ensa, which replaces the t with an s the same way -sy is derived from -ty.

  • 20: doce

  • 30: treinsa

  • 40: cuarensa

  • 50: cinuensa

after that, we can simply loan the words for larger powers of nif.

  • 100: nif

  • 101: nif uno

  • 110: nif seis

  • 120: nif doce

  • 130: nif treinsa

  • 131: nif treinsa y uno

  • 200: dos nif

  • 300: tres nif

  • 1000: seis nif

  • 1 0000: unexián

  • 1 0000 0000: biexián
