Four types of English exist in Africa, identifiable in terms of history, functions, and linguistic characteristics. West African Pidgin English has a history going back to the 15th century, 400 years before formal colonization. Creole varieties of English have a history going back to repatriation of slaves from the Caribbean and the United States in the 19th century. Second language varieties, which are the most widespread on the continent, are prototypically associated with British colonization and its education systems. L1 (First language) English occurred mostly in Southern and East Africa, and is best represented in South Africa. The latter shows significant similarities with the other major Southern Hemisphere varieties of English in Australia and New Zealand. All four subgroups of English are growing in numbers.
