What proword would you use to indicate disagreement with a previous statement?

The appropriate proword to indicate disagreement with a previous statement is "Negative." In communication, particularly in military and aviation contexts, "Negative" is specifically used to convey that the speaker does not agree with or is rejecting what was just communicated. This term helps to clearly communicate a counter to prior information, ensuring that there is no misunderstanding.

Using "Negative" provides a straightforward way to indicate that the information received was not accurate or is contrary to the speaker's stance. This is essential for maintaining clarity and decisiveness in high-stakes environments where miscommunication can lead to significant consequences.

In contrast, "Affirmative" is used to indicate agreement or confirmation, "Roger" signifies acknowledgment of the message, and "Break" typically indicates a change in topic or to separate messages, but does not convey disagreement.
