Not something I thought of a lot when I was back in US since USA is… a pretty bureaucratic name by all means. But I just realized that some countries have really fascinating names in their local language
Like how China names itself Central/Middle country in a very grandiose way (as in, we are the center of the world), or Japan being “land of the rising sun”
Deutschland means literally German Country xD
Apparently, “deutsch” originated from Medieval Latin “theodiscus”, which meant “belonging to the own people”.
