I went through this before, but in English, buns are under the larger umbrella of bread. Wikipedia for Bun starts with this: "A bun is a type of bread roll, typically filled with savory fillings (for example hamburger)."
And this is the wikipedia entry for bread roll (bolding mine):
"A bread roll is a small, often round loaf of
bread served as a meal accompaniment (eaten plain or with butter). A roll can be served and eaten whole or cut transversely and dressed with filling between the two halves. Rolls are also commonly used to make sandwiches similar to those produced using slices of bread. A
bun is a small, sometimes sweet,
bread, or
bread roll. Though they come in many shapes and sizes, they are most commonly hand-sized or smaller, with a round top and flat bottom."
So in English, it is not a separate thing but more of a subclass.
As for the mixed together thing, this is what I was referring to:
Attachment 2132
The mixed together in the dictionary quote I wrote is specifically referring to the "flour, water, and yeast or another leavening agent," part of the definition. It is unrelated to what you wrote about having other stuff mixed in, like stuffing, etc. To be clear, that definition does not disqualify anything just because it
isn't mixed together. It is simply specifying that the flour, water, and yeast/leavening agent are mixed.
As for pizza, the dough/crust is technically bread, but as a whole it is not. It is simply a pizza, just like how a hamburger has a bun, which is a bread in English as I specified above, but is not bread, and is instead called a hamburger.
I get why this can get confusing with the stuffed breads. The difference is kind of arbitrary, since even a calzone, which is essentially a stuffed bread dough, is NOT considered bread. English is super messy that way. To be clear, I am not saying this is the ideal state of bread definition, especially considering how confusing it can be, but it is indeed the current state.
It is an observation on my part, not a prescription.
I imagine Germans have a much better and clearer classification, as you guys mentioned.
