Roger

"Roger" is a term used in radio communication to acknowledge that a message has been received and understood. Originating from military and aviation usage, it simply confirms that the listener heard the transmission correctly. It does not imply agreement or action, just acknowledgment. For example, if someone says, “Please confirm you received the update,” a reply of “Roger” indicates that the message was successfully received and understood. It is a standardized part of radio language, helping ensure clear and efficient communication, especially in contexts like aviation, emergency services, and other fields relying on radio exchanges.
