What is another name for body language?

Body language is a term commonly used to describe the non-verbal signals that we use to communicate. This includes gestures, posture, facial expressions, eye contact, and various other physical movements. Referring to body language specifically as "gesture" emphasizes the role of physical movements in conveying messages or emotions without the use of spoken words. Gestures are a crucial component of body language and can vary significantly across different cultures, adding a layer of complexity to non-verbal communication.

The other options do possess some relevance to the concept of body language, but they do not capture the essence of non-verbal communication as effectively as "gesture." While expressions can refer to facial movements and behaviors may encompass a broader range of actions, "gesture" is the term that specifically ties back to the physical movements that serve as indicators of communication. "Sign" typically relates more to symbols or signals that have a specific, often codified meaning, which diverges from the broader interpretations that body language can encompass. Thus, the term "gesture" aligns most closely with the definition of body language.
