On today’s episode of Spectacular Vernacular, hosts Ben Zimmer and Nicole Holliday chat about language at the Olympics in Tokyo. They also chat with linguist Arika Okrent about her new book, Highly Irregular: Why Tough, Through, and Dough Don't Rhyme―And Other Oddities of the English Language. (Check out an essay Okrent wrote about the English spelling system.)
