Actually, I was already familiar with those words in Portuguese. However, your guide made me realize that I didn't know the Portuguese word for "South American." According to Google Translate, it's "sul-americano." Thanks for helping me learn 🙂
However, your guide is for Spanish or Portuguese, not English. This matters because most romance-language-speaking countries are taught that "América" is one continent. In contrast, most English-speaking countries are taught that North and South America are two separate continents, not one single continent called "America."
