No idea bro

I find the culture and traditions of the individual tribes absolutely fascinating, and wish we knew more about them even though we do know quite a bit already I wish we knew more!!!!!

I don't see the connection but maybe Carja is related to courage, but I know for certain that the 21st century English of the first humans to be released from the cradles would have morphed into something very different by the time of Aloy's birth, a period of 700 years.

I think the Tenakth name comes from the glitched Military Life hologram specifically.
