What signal does a referee give for a "halt" during the match?

The correct signal for a "halt" during a fencing match involves the referee raising their arm and calling out "Halt!" This action is both a vocal and visual cue that alerts the fencers to stop their actions immediately. The use of the arm to signal is essential, as it provides clarity to the competitors and any spectators or officials present. The verbal command reinforces the visual signal, ensuring that all participants are aware of the interruption in the bout, which may be due to a variety of reasons such as a violation of rules, ensuring safety, or addressing an issue on the mat.

While there may be other methods of signaling in different contexts or sports, the specific combination of the raised arm and vocalization is standardized in fencing to maintain consistency and clear communication among the referees, fencers, and spectators.
