What communication term suggests a satisfactory reception of a message?

The term that suggests a satisfactory reception of a message is "Roger." In communication, especially in radio or military contexts, "Roger" is used to confirm that a message has been received and understood. This term is widely recognized because it conveys clarity and assures the sender that their communication was successful and acknowledged.

Using "Roger" not only indicates that the receiver has heard the message but also that they comprehend it, thus signaling readiness to proceed or respond as necessary. This term is particularly important in communication where misunderstandings could lead to errors or complications, making it a critical element in effective messaging.

While affirmative responses can convey agreement, and other terms might signal lack of reception or transmission closing, "Roger" specifically denotes that the communication was effective and understood.
