This Business English podcast episode discusses the nuances of phrasing when conveying that a topic has only been superficially covered. The hosts explore various ways to express this, such as "scratching the surface," "skimming the surface," and "doing a deep dive," contrasting these with phrases like "high-level summary" and "let's keep it simple." A role-play scenario demonstrates practical application in a workplace onboarding context. Listeners learn multiple ways to indicate that more information exists without sounding robotic or repetitive, improving communication skills in professional settings. The episode also cross-references a previous episode on asking for brevity.
