View original article & transcriptTo “overhear” something can mean you hear it by chance, without trying to. “Listen in on” can mean following a conversation or meeting without joining; context decides whether that is permitted. “The walls have ears” warns that someone may be listening, while “perk up your ears” means begin listening more closely. This page distinguishes these phrases from “eavesdrop” and “spill the beans,” which appear in related RTB lessons.
Cultural note: Secretly listening to private conversations can violate trust, even when curiosity is understandable. “Overhear” usually suggests an accidental event; “listen in on” may be intentional and can be acceptable in an open class or meeting. “The walls have ears” is a caution, not proof that anyone is actually monitoring you.
Keep exploringEnglish separates an accidental fragment of conversation from choosing to listen—and from warning that privacy may be limited.
