Liteninbolt, curious, did you create this slide show, or did you radomly discover it on youtube? If so, why were you drawn to it, enough to post it on here?
Imp, to answer your question about the orgin of the Apache language and the meaning of the Apache name, I am sure you already know most, or you would not have asked.
Apache= given during the Spanish raids, meaning “Enemy” Translated by the Spanish, of course they were enemies to the Spanish. The Spanish did not have good intentions.
The Apache had two laguages, one for the warriors, and one for the tribe, so to base the warrior on the whole tribe would be wrong.
The Apache did not call themselves “Apache”. The regarded themselves as Nide= “the people”
I will not go into detail, because I am sure you are familar with most of this, but what you are familar with has been translated. One word can change an entire sentence.
To reinterate your original comment, You said that Apache would scalp you if you looked at them. That is the Spanish theory, a translated theory. Of course, the Spanish had to watch their scalps around an Apache, they were the enemy afterall. But, ask a Pueblo “Indian” about an Apache, you would hear something different, even the French version is different. So what you know is based on assumption, and we already know what you think about assumptions.
Basically, this youtube video is based on an assumption, but the intention is a good one, so it would seem harmless. How do you think it should have been dipicted to give a correct translation of the things you know?
