Why do you say "heehee?"
There are no tribes among American Indians. They each call themselves a Nation, hence Cherokee Nation, Iroquoi Nation, Crow Nation, etcetera. Or, they are simply the People, such as the Lakota People. The Navajo word that translates to People is Dine. They call themselves simply Dine (Dinay).
The Navajo and the Hopi have clans within their nations. I don't know how each of the other Nations are organized, but this is the little bit that I know.
Private joke between my friend and me. :)
Potawatomi....of which I am one.
