Sarah Ogilvie is a lexicographer and a proud and self-confessed word nerd: languages are her passion and are at the heart of her writing and scholarship. She worked as an editor at the Oxford English Dictionary and went on to write a book about the thousands of volunteers around the world who submitted words for its first edition. She has researched endangered languages in Australia, North America and most recently Indonesia. She is also the co-author of Gen Z Explained, where she analysed how 16-25-year-olds communicate with each other, in words, images and emojis. She’s currently a senior research fellow at the University of Oxford. Her musical choices include Monteverdi, Allegri, Mozart and Nina Simone. Presenter: Michael Berkeley Producer: Clare Walker
