Czech sign language is a special way that people who can't hear or speak use to talk to each other. It's like a secret code that only they understand! Just like how some people speak English or Spanish, people who use Czech sign language use special hand gestures and body movements to communicate with each other.
Imagine you and your friend are playing a game of hide-and-seek and you want to tell her where you're hiding, but you don't want anyone else to hear you. So, you decide to use secret hand signals to communicate with her instead of talking out loud. This is kind of like how people who use Czech sign language communicate with each other—they use special signs and movements with their hands and body to share their thoughts and feelings.
When people use Czech sign language, they don't just use their hands. They also use their whole body to communicate! They might move their arms, shoulders, and even their facial expressions to show what they mean. For example, if they want to say they're happy, they might smile and jump up and down. If they're sad, they might frown and slump their shoulders.
Just like how there are different accents when people speak English, there are also different types of sign language depending on where you are in the world! In Czech Republic, they use Czech sign language, which is different from American sign language or British sign language. People who use Czech sign language can communicate with each other all over Czech Republic, and it helps them to understand and connect with each other.
