In English as a global language, the author, David Crystal, tells the story of the spread of English around the world. He attempts to explain how English achieved its current status as a global language and he speculates on the possible future of English as a world language. He considers the possibility of English being superseded by another world language or of it evolving into a family of languages. This essay considers some of the issues raised in this book, which have implications for the linguistic ecology of Africa. The educational, political and social implications of the current and future status and use of English in Africa are reviewed, as well as the impact of the language on local languages.
