Language helps us to connect with one another – and, yet, so often it seems our words fail us. This hour we’ll talk with linguist John McWhorter about how we use profanity – and which words some of us should never use. We’ll talk with Anna Sale of the “Death, Sex and Money” podcast about strategies for having difficult conversations. And psychologist Katherine Kinzler explains how the actual sound of our voices affects how people hear what we’ve got to say.
