Literally: it is good (alternatively: it is well).
This is the way to say hello in Navajo, and is the common Navajo greeting. Meeting people, these days, begins with the greeting, but it could also be used as a parting farewell. It’s not common to tell someone “goodbye,” but instead “see you later” or “Yá’át’ééh.”
Additionally, “Yá’át’ééh abiní” is the way to say good morning in Navajo. Here you’re saying “it is good, the morning.” Notice -át’é-, it is another word meaning “it is.”
It can also be used with ‘shił’ as in “shił yá’át’ééh” to mean “I like it.” Change it to nił or bił and you’ve got “you like it” and “he/she/it likes it” (Navajo pronouns tend to be gender neutral).
I hope everyone’s day is good!
