We often use gestures for communication. For example, soccer players sometimes communicate with each other without words. They use body movements and contact. In such cases, gestures are more useful than words.
There are many gestures. We use them with words or without words.
Some gestures are the same in many coutries. For example, the V-sign is the most popular. Almost everyone knows it. Gestures are useful when we talk with foreign people.
Maybe you know Chaplin's silent moveis. People do not talk in them. They use many gestures.
We can communicate across cultures with gestures.
Tom: How do you show “Be quiet”?
Ken: We put a finger on our lips.
Tom: It's the same in the USA.
Ken: Yes. This as popular as the V-sign.
Tom: Then, how about the gesture for “Come here”?
Ken: We move our hands and fingers like this.
Tom: Oh, It's different. In the USA it may mean “Go away.”
