Martha reviews the new book, Dreaming in Hindi by Katherine Russell Rich, a memoir about setting out to learn a second language in mid-life. Rich spent a year in India to learn Hindi, and became so fascinated with the process that she went on to interview experts about the mechanics of second-language acquisition and how it affects the brain. Publisher’s Weekly has an interview with Rich. Grant discusses an article about what happens to the mother tongue voice when first-language speakers of indigenous languages in India learn English and then spend years focused on speaking and writing in their adopted tongue. This is part of a complete episode.
