Irina Morgan is a high level interpreter. Being bi-lingual in Russian and Ukrainian means she's in demand whenever Vladimir Putin or President Zelensky give a press conference requiring simultaneous interpretation. Irina talks to Michael about the language do's and don'ts of live translation, and about how she puts herself into the mindset of someone like President Putin in order to give an accurate representation of his distinct man-of-the-people hard man linguistic style. By contrast Volodymyr Zelensky is a linguistic free-styler - like following jazz, Irina says.

Michael Rosen is learning Yiddish. Every Sunday, he joins other adults in an evening class, conjugating verbs and practising rhymes.

For this episode of Word of Mouth, he invites his teacher, Tamara Micner, to join him in the studio. The pair have fun swapping family stories and sharing how they were first exposed to Yiddish. Tamara explains where the language came from and how it's evolved, and they discuss its connections to English. We also hear what Michael is like in class as a new learner, as he wraps his head around the pronunciation and patterns of this language which links him to his family history.

Andy West talks to Michael Rosen about his work discussing philosophy in prisons around England. His book The Life Inside is a memoir of his own experience of the justice system through his family.
