A social gesture is a non-verbal action that conveys meaning or emotion in social interactions. These gestures can include movements like waving, nodding, or handshakes, and they often help to communicate feelings such as greeting, agreement, or farewell. Social gestures vary across cultures, with some actions having different meanings in different societies. Understanding social gestures is important for effective communication. For example, a thumbs up can signify approval in many cultures, while in others, it may be considered offensive. Being aware of these differences can enhance interpersonal relationships and reduce misunderstandings in diverse settings.
