How does nonverbal communication function in relation to verbal communication?

Nonverbal communication complements verbal communication by providing additional context and emotional nuance to spoken Words. It includes body language, facial expressions, gestures, and tone of voice, which can reinforce or contradict the verbal message. For example, a smile can enhance a positive statement, while crossed arms may suggest resistance, even if the Words are agreeable. Together, both forms of communication create a more complete and effective exchange of information.
