What is the difference between an English breakfast and a British breakfast?

An English breakfast refers specifically to the traditional cooked breakfast associated with England, defined by its own core components and conventions. A British breakfast is a broader, informal term that encompasses the regional breakfast traditions of England, Scotland, Wales, and Ireland, each of which has its own recognised variations. In this sense, an English, Scottish, Welsh, or Irish breakfast could all reasonably be described as British, but they are not interchangeable.
