Anyone proposing to write a history of the English language in the twentieth century begs a number of questions, which it is necessary to answer at the very outset of what might seem an excessively ambitious project.

Isn't the topic too vast and complex for a single author to tackle? If one bears in mind that in contrast to historians of Old and Middle English, who in general suffer from a poverty of evidence, the historian of recent and contemporary English is deluged with data and, in principle, needs to write separate histories of several richly documented standard and nonstandard varieties, and a history of contact and influence among them, the answer to this question is an obvious “yes.”
