Moira speaks with Fresh Air commentator and linguist Geoff Nunberg, who discusses his book The Years of Talking Dangerously and assesses the impact of words in a dynamic, changing world. In the book, he explains why grammar buffs are drawn to sarcasm, and deftly unpacks the telling phrases of our national conversation, from progressive to elite to change, as well as the national conversation itself.
