Pizza, hot dog...to name but a few! These words can't be translated in engliah. Why? Because they are strictly connected to their original culture. They are "culture-bound" elements.
The history of pizza is long and complicated! Some forms of pizza are said to be popular during the Neolithic Age, can you imagine!
Anyway, legend has it that the pizza maker Raffaele Esposito came up with the well-known pizza Margherita in honor of Queen Margherita, who came to visit Naples.
