For hundreds of years, people living in Louisiana's bayou country have spoken French. But rising sea levels are submerging entire communities, forcing people to abandon their homes. As native French speakers move away, will the language survive in this most French of American states? We hitch a ride to the bayou with linguist Nathalie Dajko.

They're not in American dictionaries yet, but the terms, 'punching up' and 'punching down' are on the lips of many comedians. With the help of linguist and journalist Ben Zimmer and British comedian Richard Herring, we trace the migration of these words from sports to cable news to comedy. Along the way, we catch up with the history of performers and writers targeting the rich and powerful (punching up) or mocking the oppressed and vulnerable (punching down).

In reporting this episode, we owe a debt of gratitude to this piece in The Baffler and this episode of WTF with Marc Maron.

In this episode, we tell the inspiring, heartbreaking story of Radio Haiti. For several decades, the station broadcast not just in French, spoken by Haiti's elite, but also in Kreyòl, spoken by rich and poor alike. The Kreyòl-language programs communicated directly with the rural poor—the 'outside people'—popularizing issues of inequity and corruption. Helping us tell Radio Haiti's story are Michèle Montas, widow of the station's assassinated owner Jean Dominique, and archivist Laura Wagner.

Does your grandmother call a chest of drawers a dresser? Or a bureau? Or perhaps a chiffonier? Over the years and across regions, Americans have favored many different words for furniture—and much else. Since 1929, the Linguistic Atlas Project has been documenting these lexical changes. We tell the story of the Project, from its early days of interviewing retired male farmers, through its initially clumsy attempts to engage Black Americans, to today's scientific, demographically diverse approach.

If you’ve ever set boundaries, taken up a gratitude practice or manifested, you’re already well-versed in the language of self-help. Over its long history, self-help has acquired its own lexicon, often repurposing words along the way. Nowadays, the flavor is American but that wasn't always the case. We delve into the past and present of self-help language with Kristen Meinzer, co-host of the podcast, By the Book.

Why do so many of us laugh at a word like 'poop' but not at, say, 'treadmill'? Is it all down to their meaning? Or are we also responding to the sound of these words? Psycholinguist Chris Westbury set out to discover the answer. Assisted by an inventive computer, Westbury and colleagues dreamed up a bunch of non-words (like "snunkoople"), and tested their funniness on the public. We discuss the results, as well as our favorite funny words—and we get some authentically amusing help from comedians Joanna Hausmann and Filip Jeremic.

When Julie Sedivy was four, her Czech family emigrated to Canada. In this episode we hear how Julie became estranged from her native Czech, only to rediscover it after the death of her father. Julie Sedivy's linguistic memoir is Memory Speaks: On Losing and Reclaiming Language and Self.

Is it easier to sing than speak in another language? Artist Wen-hao Tien is putting that idea to the test. She has invited friends from around the world to teach her a song in their mother tongue. Patrick listens in on a few of the lessons and also teaches Wen-hao one of his favorite (punky) songs.

Music in this episode by Leimoti, Ofelia Moore, and Honeycutts. Photo, courtesy Wen-hao Tien, shows Suzi Hamill teaching Wen-hao Tien a Mozart aria.
