Forms of greeting vary across cultures and contexts. Common greetings include a handshake, a wave, or a nod. In some cultures, people may bow or place their hands together in a prayer-like gesture. The choice of greeting often depends on the relationship between individuals and the setting, such as formal or informal occasions. In addition to physical gestures, verbal greetings play a significant role. Phrases like "Hello," "Good morning," or "How are you?" are widely used. Some cultures have specific greetings for different times of the day or occasions, such as Chinese "Ni hao" or Spanish "Hola," reflecting their unique traditions and social norms.
