In plain English: Pizza is a round flatbread topped with cheese and other ingredients that you bake in an oven and eat with your hands.
"My favorite dinner is a large pepperoni pizza."
Usage: Use "pizza" to refer specifically to the baked Italian dish made with a thin crust, tomato sauce, cheese, and various toppings. Do not use it as a verb or to describe any round food item that lacks these traditional components.
The word pizza entered English in 1931 from Neapolitan dialect, where it originally referred to a type of cake or pie derived from Byzantine Greek. Although its ultimate roots are uncertain and may trace back to Latin words meaning "painted" or "pounded," the term specifically evolved in southern Italy before spreading northward.
