Hágoónee’

The Navajo word hágoónee’ is commonly used in parting, and it roughly means “okay/alright then” in English.

It’s almost like saying, “Okay, things are settled. See you later.”

Another useful parting expression is yá’át’ééh – the common word for “hello.” It’s literal meaning is “it is good,” so that could denote a conclusion to events as well.
