Gestures are movements of the body, particularly the hands and arms, that convey meaning or express feelings. They play a crucial role in communication, often complementing or enhancing verbal messages. For instance, a thumbs-up gesture typically signifies approval, while a wave can indicate greeting or farewell. In different cultures, gestures can have varied meanings, making them an essential aspect of understanding social interactions. Misinterpretations can lead to confusion, highlighting the importance of context. Overall, gestures enrich our communication, allowing us to express emotions and intentions beyond words.
