In this episode of the All Ears English podcast, the hosts tackle a common grammar question: where to place "not" in English sentences, especially when negating infinitives and subordinating conjunctions. They clarify that while it's generally acceptable to position "not" either before or after the infinitive, keeping multi-word subordinating conjunctions—like "in order to"—together tends to sound more natural to native speakers. Additionally, splitting infinitives with "not" is permissible and can enhance emphasis or subtly shift meaning. Ultimately, the episode encourages listeners to prioritize clear communication and natural speech over rigid grammar rules.
