Which proword is appropriate to confirm readiness to receive further communications?

The appropriate proword to confirm readiness to receive further communications is "GO AHEAD." This term is specifically used in radio communications to indicate that the receiving party is ready to accept additional information. When this proword is used, it conveys a clear, affirmative response that the listener is prepared for the next transmission.

In contrast, other prowords serve different purposes in communication contexts. For instance, "OVER" indicates that the speaker has finished talking and is expecting a response, while "STAND BY" suggests that the listener should pause and wait before proceeding. "ALL CLEAR" may be used to indicate that there are no further hazards but does not confirm readiness for new instructions or communications. Thus, "GO AHEAD" is the most appropriate choice for explicitly confirming readiness to receive further communication.
