Which of the following is not a type of nonverbal communication?

Vocabulary is not a type of nonverbal communication because it refers specifically to the words and language people use to convey their thoughts and ideas. Nonverbal communication, on the other hand, includes forms of communication that convey messages without the use of words. This encompasses a range of physical expressions and cues, such as posture, gestures, and facial expressions. Posture can indicate confidence or defensiveness, gestures can emphasize or complement what is being said, and facial expressions can convey emotions like happiness, sadness, or surprise. All of these contribute to how a message is received and interpreted, highlighting the importance of nonverbal cues in interpersonal communication.
