The relationship between the many dialects of English used throughout the world is depicted in the diagram.
American English and British English are the two primary varieties of English. Geographically, the British English branch is vast. From the West Indies via the British Isles, Africa, the Indian subcontinent, the Far East, and Australasia, it spreads throughout multiple continents (Australia and New Zealand). It contains a vast number of additional variants, such as Jamaican English, South African English, and Australian English, in addition to the four varieties of English spoken in the British Isles (i.e., in Ireland, Wales, Scotland, and England).
The American division primarily serves the American continent. It includes dialects of English used in Canada and in various parts of the United States.
Only the Philippines in East Asia and American Samoa in the Pacific region outside of the continent are affected by it.
In a nutshell, the figure demonstrates that English has essentially spread to every corner of the world, much like the economic and political power of the Anglo-Saxon countries.
