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”
Finland (Suomi) basically means a swamp (suo).
If you look at the etymology, there are other explanations of the origins, but a modern person would associate the name with a swamp. I guess it makes sense with all the lakes.
