microphone
"Microphone" is a straightforward word with essentially one core meaning, though it appears in a few interesting contexts. It refers to a device that captures sound, and you will encounter it in everyday life, music, broadcasting, and technology.
A microphone is a piece of equipment that picks up sound — like your voice or music — and converts it into an electrical signal so it can be recorded, amplified, or transmitted. Think of it as a 'sound collector'. When you speak into one, your voice can be heard by a large crowd, recorded on a computer, or sent over a phone call.

In a figurative sense, 'the microphone' or 'the mic' can represent the opportunity to speak, perform, or share your opinion in front of others. When someone says 'pass the microphone', they mean it is someone else's turn to speak or lead.
