Clear signals are distinct and easily recognizable indicators that convey specific information or messages. They can be found in various contexts, such as communication, traffic, or even nature. For example, a traffic light uses clear signals—red for stop, green for go—to guide drivers and pedestrians safely. In communication, clear signals can include verbal cues like tone of voice or non-verbal cues like body language. These signals help convey emotions and intentions effectively. For instance, a smile can signal friendliness, while crossed arms may indicate defensiveness. Understanding these signals is essential for effective interaction.
