How to Say “Bad Words” in Navajo

By Douglas Juan • Updated October 2, 2026

saad doo yáʼáshóonii

The Navajo phrase for bad words is saad doo yáʼáshóonii.

What does it mean word for word?

The phrase is composed of saad (word), doo (not/negation) and yáʼáshóonii (the one that is good/pleasant).

Did you know?

In traditional Navajo culture, the power of saad is believed to be so great that speaking something into existence can actually make it happen.
Because the phrase relies on the concept of 'pleasantness', using 'bad words' is seen as a disruption of harmony rather than just breaking a rule.
The negation particle doo is actually a shortened version of the word dooleeł, which means 'it will be'.

Hello, I am Douglas, an absolute Navajo language enthusiast. My passion for this beautiful language, coupled with my love for sharing knowledge, has inspired me to write numerous guides on common phrases and words. I enjoy exploring words from "Angel" to "Yucca" and everything in between. In my leisure time, you'll often find me experimenting with traditional Navajo recipes, strolling amidst nature, or enjoying a robust cup of traditional Navajo tea. Apache is spoken not far from Navajo, and it has become another language close to my heart, so you will now find my guides to Apache here too. Haash yinilyeii (that's how I say 'that's me' in Navajo)!
