IPA: /ˈiːvzˌdrɒpə/
KK: /ˈivzˌdrɒpər/
A person who secretly listens to the conversations of others without their knowledge.
The eavesdropper hid behind the door to hear what they were saying.
Eavesdropper → It is formed from "eaves" (from Old English *yfes*, meaning the edge of a roof) and "dropper" (from "drop" meaning to fall). The word refers to someone who listens secretly from the edge of a roof or nearby place, as if listening to drops of conversation.
Imagine someone listening from the 'edge of a roof' ('eaves') to catch 'falling' words ('drop') — that's how an eavesdropper hears secrets.
