Why do we 'let the cat out of the bag' or 'go the whole nine yards'? What is a hackle and why might it be raised? What does it mean to 'fribble'? Or to have a 'schnapsidee'? And what are 'cupid's kettle drums'?

Michael Rosen and Dr Laura Wright are joined by Paul Anthony Jones, the writer behind the popular etymology blog Haggard Hawks to talk about the origins of common idioms, the stories behind words we use every day, and the forgotten words Paul would like to see brought back into use.

Paul is the author of six books of word lore and linguistic trivia, including Haggard Hawks and Paltry Poltroons: The Origins of English in Ten Words, The Accidental Dictionary: The Remarkable Twists and Turns of English Words and - most recently - The Cabinet of Linguistic Curiosities: A Yearbook of Forgotten Words.
