What is the original name of the signal flags used in communication?

The term being referred to as the original name for signal flags is "WigWag." This method of communication using flags involves moving them in specific patterns to convey messages, particularly in military and naval settings. The WigWag signaling system typically utilizes a single flag on a pole, where the position and movement of the flag represent different letters or signals. This approach to communication dates back to the 19th century and was primarily used by the military for sending messages over distances where other forms of communication were not practical.

In contrast, while Semaphore also involves flags and is often used in signaling, it specifically refers to a system employing two flags held in different positions to represent letters. "Buntline" and "Signalman" do not specifically refer to the original concept of flag communication. Buntline can refer to a type of knot or line used on ships, and Signalman generally refers to the person trained to operate the signaling equipment. Therefore, the best representation of the original name linked specifically to signal flags is indeed WigWag.
