The flow chart illustrates the global distribution and varieties of the English language.
Overall, the diagram is divided into two principal branches: American English and British English. Together, these branches ultimately lead to 27 sub-varieties, highlighting the extensive geographical spread and diversification of English worldwide.
Regarding the American English branch, it is separated into two secondary divisions: the United States and Canada. Within the United States, several regional varieties are identified, including those spoken on the West Coast, the Midwest, the Northeast Coast, and the South, as well as in Puerto Rico. In addition, English is also used in American territories such as the Philippines and American Samoa. By contrast, English in Canada is classified into two main forms: Anglophone Canadian English and Francophone Canadian English.
Turning to the British English branch, this category is further divided into six secondary branches with wide geographical variation. Notably, India and Pakistan together account for the greatest diversity, with six distinct forms of Indian English. The British Isles comprise four varieties: Irish, English, Scottish, and Welsh. Meanwhile, English in Africa is grouped into East African, West African, and Anglophone forms. In comparison, regions such as the West Indies, Australasia, and the Far East contain no more than two varieties each.
