Tádiin is the Navajo word for the number 30. (Not to be confused with tádídíín/tadidiin, which is cornpollen.)

When you get to 30, you’ll start using dóó ba’aan to construct your numbers. Dóó ba’aan used with numbers means “and then” as in 30 and then 4 (34). We touched a little on this in our post for counting béeso (money).

• 30 - tádiin
• 31 - tádiin dóó ba’aan t’ááłá’í
• 32 - tádiin dóó ba’aan naaki
• 33 - tádiin dóó ba’aan táá’
• 34 - tádiin dóó ba’aan dį́į́’
• 35 - tádiin dóó ba’aan ashdla’
• 36 - tádiin dóó ba’aan hastą́ą́
• 37 - tádiin dóó ba’aan tsosts’id
• 38 - tádiin dóó ba’aan tseebíí
• 39 - tádiin dóó ba’aan náhástéí
• 40 - dízdiin

You’ll notice that you don’t have to say dóó ba’aan on the multiples of ten; you don’t need to say 40 and then zero. This is the way you construct numbers all the way to 99. You can use multiples of 10 to continue this (from this post).
