This week, we're bringing you a very special episode produced in partnership with Public Radio International. Along with a panel of speakers including NYPL's Denise Hibay, the World in Words' hosts Patrick Cox and Nina Porzucki examine the state of endangered languages around the world: Why do languages become endangered, and how have some speakers worked to ensure a future for their native tongues? In this special live podcast taping, we explore what's happening to endangered languages from Ainu to Zaza.
