Nóomba (11-20)

Here’s the next series of the Navajo number system.

Since you’re familiar with the base numbers 1-9, to create the “teen” numbers simply append “-ts’áadah” to the end of those numbers. Once you get to 20, as with any multiple of 10 up to 90, this attachment becomes “-diin”. See:

  • 11) ła’ts’áadah
  • 12) naakits’áadah
  • 13) táá’ts’áadah
  • 14) dį́į́’ts’áadah
  • 15) ashdla’ts’áadah
  • 16) hastą́ts’áadah
  • 17) tsost’idts’áadah
  • 18) tseebííts’áadah
  • 19) náhást’éíts’áadah
  • 20) naadiin
  • Notice how t’ááłá’í can be shortened to ła’. In some cases, you may also notice with numbers 15 and 16 that some people tend to leave out the “-ts’-” pronunciation.

Take the weekend to practice these and see how you similar they are to the base 10 numbers.
