Meaning: possibly, or about, or maybe.
This is a common word in conversational Navajo. One would use daats’í in an otherwise definitive statement or question in order to associate it with a kind of uncertainty, or guess.
“Karen knows” would become “Karen probably knows.” “How many years is that boy?” would become “About how many years is that boy?” “We will work today” would become “Maybe we will work today.”
So if you hear daats’í, you know you’ll be dealing with estimates, or guesses – roughly.
