Over and out
Meaning
This phrase signals the definitive end of a radio transmission and the expectation of no further reply, or more broadly, the conclusion of a conversation or activity.
Origin
In the crisp, regulated world of early 20th-century radio, every word carried precise meaning. "Over" told your listener you'd finished speaking and expected a reply, like a baton passed in a relay. "Out" was the definitive sign-off: I'm done, no response needed, transmission ended. The popular combination, "Over and out," is technically a contradiction in strict military and aviation protocol, as you can't simultaneously await a reply and terminate contact. But the phrase, often popularized by Hollywood's dramatic flair after World War II, quickly became an iconic, emphatic declaration, universally understood as the final, absolute conclusion of a conversation—a mic drop into the ether.
Examples
- Well, my presentation is finished, so that's me over and out for the day.
- After sharing all the intel, the pilot signed off with 'over and out,' disconnecting the communication.
