Michael Rosen is joined by linguist Dr Catherine Laing to discuss onomatopoeia and other words that sound like their meanings. Not just words for sounds like 'crash' and 'bang', or words for animal noises like 'woof' and 'quack', but also other words which perhaps hold something of their meaning within their form. Is there something rough about the word 'rough'? Does 'smooth' feel smooth? And how can we play with this in everyday speech and in poetry?

Michael Rosen talks to criminal defence barrister Joanna Hardy-Susskind about the legal language of Crown Court cases in England and Wales. From the grandeur of the courtroom and stock phrases like "with respect to my learned friend" to the more colloquial directness of talking to a defendant. How do barristers build persuasive arguments when talking to a jury, or when discussing legal matters with the judge? Do weak arguments hide behind elaborate language? Do the best barristers use more stripped back language? And how do they deliver their words? The tone, the pace, the performance.

Michael Rosen talks to Samantha Ellis, author of Chopping Onions on My Heart, about her efforts to keep alive the language of her parents: Judeo-Iraqi Arabic.

Michael Rosen asks what happens to people's sense of identity and social being when speaking becomes hard. Jonathan Cole has interviewed people with conditions such as cerebral palsy, vocal cord palsy, spasmodic dysphonia and post-stroke aphasia. They describe in their own words what the experience of not being able to express themselves is like, the frustration and isolation as well as the adaptation and resilience.

Michael Rosen talks to sociolinguist Dr Haru Yamada about how we listen in different ways across different cultures and social groups. It's the side of conversation that is not about talking, but which is equally - if not more - important to how we communicate. Haru is the author of 'Kiku: The Japonese Art of Good Listening', and she believes that listening is something we can all learn to do better in order to build stronger relationships with each other, and with the world around us.

The use of punctuation is rapidly changing within the quickfire back-and-forth of instant messaging. Are these changes causing misunderstandings? Presenter Michael Rosen and his guest Dr Christian Ilbury discuss. Is the full stop on the way out? What about capital letters? Exclamation marks and question marks seem to be holding their ground, but what about the rest?

Michael Rosen talks to sociolinguist Philip Seargeant from the Open University about where our street names come from, including Whip-Ma-Whop-Ma-Gate in York, and Michael's old address, Love Lane. Also, have you ever thought about the difference between a street and a road? Are there regional differences in the names given to streets? And why are street names sometimes changed?
