Michael Rosen and Dr Laura Wright interview the eminent US linguist George Lakoff about the new political words coming out of the US right now, mainly from the alt-right, and the effectiveness of Trump's use of language. George Lakoff is the former Distinguished Professor of Cognitive Science and Linguistics at the University of California at Berkeley. His thesis is that people's lives are significantly influenced by the central metaphors they use, whatever their political beliefs, and that how information is framed is crucial in how it is received.

Michael Rosen is joined by writer Matthew Engel and linguist Dr Lynne Murphy to discuss the Americanisation of English. Is the pace of Americanisation of British English really increasing? Why do Americans say eggplant and sidewalk, rather than aubergine and pavement? Why does your spellchecker insist it's 'color' not 'colour'? Do Americans complain about the 'Britishisms' creeping into use in the States as much as we complain about Americanisms in use in the UK? Does it really matter if British and American English begin to be used interchangeably and could we stem the flow if we tried?
