"If you want to hide something in the 21st century world, you don't need to create a James Bond style plot. Just cover it in acronyms".

Gillian Tett is a columnist at the Financial Times, but she initially trained as a cultural anthropologist, studying marriage rituals in Tajikistan.

She joins Michael Rosen to discuss how the study of language has been vital to her work, who continues to see the world through the lens of an anthropologist. The pair talk about the etymology of words like 'company', 'office', and 'bank', why we should all speak more like the Dutch, how Brits in the workplace are more similar to the Japanese, and why it would be useful for all of us to think more like an anthropologist.

Gillian Tett is the author of Fool's Gold, The Silo Effect, and Antho-Vision.

Michael shares listeners' stories about the words and phrases passed down in their families that they keep using, and what they mean to them. With Rob Drummond, Professor of Sociolinguistics at Manchester Met University, and author of You’re All Talk: why we are what we speak. Producer Beth O'Dea, BBC Audio Bristol

Michael Rosen talks to neuroscientist Dr Julia Ravey about whether we think and act differently when speaking a non-native language.

More and more people are finding themselves speaking multiple languages in our cross-cultural societies. But when we communicate in a different tongue, do we become a different person? From the decisions we make to the memories we form, research in neuroscience and psychology has begun exploring this fascinating area, which not only offers insights into the linguistic brain, but also calls into question if our ‘core self’ is a as stable as we like to think it is…

Michael Rosen explores how language has become an online commodity, with Dr Pip Thornton, Chancellor's Fellow at the University of Edinburgh. Dr Thornton explains, with the help of auction props and a receipt machine, what happens to the words that we put into an online search and how the engines make money from our words and phrases. We discover why William Wordsworth's daffodils and clouds have had their context 'stolen', how Lewis Carroll wrote an incredibly 'cheap' poem and why mesothelioma is the most 'expensive' word. Plus Michael proposes a new form of poetry - the Monetised School of Poetry.

Michael Rosen is joined by language scholar Ruanni Tupas, to discuss Unequal English - how native English is perceived differently, depending on where you come from.

Ruanni, who's from the Philippines and also spent two decades in Singapore, has spent his career thinking about what it means to be a native English speaker when you come from somewhere other than the West. He chats with Michael about his own experience of speaking four languages (English and three Philippine languages), how being judged by how he spoke English at university affected the rest of his life and research, and what it means for his children speaking English as a first language, havng grown up in Singapore. They also discuss what is really meant by English as a 'global language', and why he prefers thinking of multi-lingualism as having a language repertoire.

Ruanni Tupas is Associate Professor of Sociolinguistics at UCL, London.

Grant Barrett is a lexicographer, linguist, author, editor, founder of Wordnik and Head of Lexicography at Dictionary.com. He also co-hosts A Way With Words, a phone in show about language, which airs coast to coast across the United States. He and Michael discuss the joy of flicking through a dictionary with friends vs the fast return of an online look-up, the history of dictionaries, and Grant's favourite area of language: sociolinguistics - "where the rubber meets the road", as he puts it.

Isy Suttie is an actor and comedian best known for her role in Peepshow and her one woman show Love Letters on Radio 4 as well as many other shows and podcasts. Here she talks to Michael Rosen about writing her comedy and what informs it. She grew up in Matlock in Derbyshire and a deep love as well of knowledge of the place and its people find their way into her humour. Words ending in consonants too are much funnier than those ending in a vowel she says. And as for learning Welsh to impress her partner her song written to show off her language skills to him is a linguistic masterpiece!

Michael Rosen talks to Ben and David Crystal about the Shakespeare quotes we use every day, without even realising.

We’ve all heard someone roll their eyes and say “the lady doth protest too much, me thinks” - or head back to their desk muttering “once more unto the breach!” Shakespeare had a way with words that makes his writing extremely relatable, even today. Ben and David Crystal tell Michael why so many of the bard’s sayings have slipped into our everyday chat.

Susie Orbach talks to Michael Rosen about the use and misuse of “therapy speak”. With the rise of mental health awareness, it seems to have leaked out of the therapist’s office and into our homes. Instead of saying someone’s getting on our nerves, we talk about “boundaries”; instead of accusing someone of lying, we call them a “gaslighter”; instead of telling someone we’re listening, we say we’re “holding space”. But do these words mean what we think they do? And do they help or heighten the issues we are trying to discuss?

Michael Bond author of 'Fans' talks to Michael about the words and language different fan groups have as a shared means of communication.
