What is English? Ask any speaker of English, and the answer you get may be “it’s what the dictionary says it is.” Or, “it’s what I speak.” Answers like these work well enough up to a point, but the words that make it in the dictionary are not always the words we hear being used around us. And the language of any one English speaker can differ significantly in pronunciation and word order from the English of another, particularly today, when two out of three English speakers have learned English as a second or third language. In What Is English? And Why Should We Care?, Tim Machan addresses these deceptively complex questions in order to suggest the ways in which definitions of English always depend on speakers’ definitions of themselves.
