What phrase did the Code Talkers use for "message"?

The phrase used by the Code Talkers for "message" is "Ts’íiyiz," which translates to "to speak." This choice reflects the functional aspect of sending messages, emphasizing communication and the conveying of information. The Code Talkers developed a unique vocabulary based on their Native American language, where specific terms were assigned to military concepts in a way that was both secure and effective for conveying critical information during World War II.

The other options do not serve this purpose in the context of military communication. "Dibé," which means "sheep," does not pertain to the act of sending or conveying messages at all. "Ch’éézh," meaning "horse," is unrelated to communication. Similarly, "Yazzie," which translates to "little," does not connect to the concept of a message or communication in the same way that "Ts’íiyiz" does. Thus, the correct answer effectively encapsulates the notion of messaging in the context of the Code Talkers' communication system.
