What is one of the purposes of nonverbal communication?

One of the key purposes of nonverbal communication is to express emotion. Nonverbal cues such as facial expressions, body language, gestures, and posture often convey feelings and emotional states that may not be articulated through words. For example, a smile can indicate happiness or approval, while crossed arms might suggest defensiveness or discomfort. This ability to communicate emotions without words is essential in building rapport and understanding in interpersonal relationships, both in personal contexts and professional settings.

While nonverbal communication can indeed have roles in other areas—such as pacifying conflict, providing feedback, or regulating conversation length—expressing emotion stands out as a fundamental aspect that enhances and complements verbal messages. Emotions are often complex and nuanced, and nonverbal signals can convey these subtleties effectively, making them a crucial element of human interaction.
