Many people don't realize that there are several different dialects of Spanish. I've always known this because my parents are from different hispanic cultures. My mother is from Puerto Rico, a territory of the United States, and my father is Mexican. By and large, the language is the same, but there are some words thats differ.
Like empanadas. In Puerto Rico, they are thinly pounded steaks breaded and pan fried, served with rice and beans, no gravy. In Mexico, they are meat or fruit pastries. In Puerto Rico, those pastries are called pastellios.
