In this episode of the All Ears English podcast, the hosts explore how to naturally ask about the origins of slang and idioms in English conversations. They introduce three key phrases to kick off these discussions: "Where's that from?", "What's the background of that?", and "Do you know the origin?" Through a role-play scenario, they illustrate how to use these phrases effectively. The hosts highlight that asking about word origins not only builds connections but also encourages deeper conversations, reflecting a genuine interest in the language's history and evolution. Additionally, they point out that understanding the background of slang and idioms can significantly enhance language learning and retention.
