That's What They Say is a delightful podcast about the history and modern-day use of the English language. For the past several years, Michigan Public Radio's Rina Miller and University of Michigan English professor Anne Curzan have hosted the program, which airs on Sunday mornings. Readers can browse and listen to the show's complete archive on Michigan Public Radio's website. These short, four- to five-minute episodes contain endless tidbits of entertaining trivia, but they also provide perspective about how language develops over time and the ways it is employed to serve a variety of social and cultural purposes. For example, in one episode, Curzan breaks down the common practice of using "indirect speech acts" to sound more polite. People tend to ask, "I was wondering if you know what time it is?" rather than the allegedly brasher-sounding "What time is it?" In another episode, Curzan describes the many grievances of Richard Grant White, who bemoaned the decline of the English language back in the 18th century. White called the word real estate "a pretentious intruder into American life" and declared donate to be an "utterly abominable" verb.
