Final answer:
Body language refers to the movement of part of the body to communicate and includes gestures, postures, and facial expressions. It is a form of nonverbal communication that can convey emotions and messages.
Step-by-step explanation:
The movement of part of the body to communicate is known as body language. Body language includes gestures, postures, and facial expressions that can convey emotions, intentions, and messages without using words. For example, a smile can indicate happiness or friendliness, while crossed arms may signal defensiveness or hostility.
Body language is an important form of nonverbal communication, and it can vary across cultures. Different cultures may interpret certain gestures or postures differently. It is important to consider cultural context when interpreting body language.
In addition to body language, paralanguage and kinesics are also part of nonverbal communication. Paralanguage refers to vocal cues such as tone, pitch, and accent, while kinesics specifically focuses on body movements and gestures.
