Gesture

A gesture is a movement of the body, especially the hands or arms, used to communicate a message or express an idea without words. It can be intentional or subconscious, serving as a visual cue to convey emotions, instructions, or reactions. Common examples include a wave to say hello, a thumbs-up for approval, or a nod to indicate agreement. Gestures are a fundamental part of nonverbal communication, helping to clarify or enhance spoken language, and can vary across different cultures.
