I'm brazilian and I had no idea about the meaning of some states' names, derived from Tupi-Guarani's (two ethnic group of brazilian amerindians) languages....Goiás(People from Guaiá), Acre(Green River), Pará (Sea), Piauí (Piaba Fish River), Roráima and Rondônia( top northest), even Ceará (Green Waters)!! Thanks for that!
I showed this to my Brazilian boyfriend and he always wondered what some of the states names were. We both really enjoyed this a lot. "Bad for Navigation" is my favorite. So glad I came across your blog! It's already been very useful and informative! Obrigada! Aubry | http://aubryama.blogspot.com/2014/11/6-weeks-until-i-leave-for-brazil_48.html
