What does the term "over" indicate in communication?

The term "over" in communication signals that the speaker has completed their transmission and is awaiting a response from the listener. This term is often used in radio communication to clarify that the speaker's message has ended, and they are inviting the other party to reply.

When someone uses "over," they clearly communicate that they expect the listener to respond, which helps maintain an organized conversation flow, especially in environments where clarity and brevity are essential, such as in radio communications or emergency situations. Using "over" indicates a transition from the speaker's turn to the listener's turn, ensuring smooth interaction between parties.
