Okay kiddo, have you ever seen someone who can't talk use their hands to communicate? That's called sign language, and in Poland they use something called the Polish manual alphabet to do it.
The Polish manual alphabet is a way for deaf people or people who can't speak to communicate using their hands. It consists of 23 different hand signs, one for each letter of the Polish alphabet.
Each hand sign is made by holding your hand in a certain position or shape that corresponds to a specific letter. For example, to sign the letter A, you would hold your fist with your thumb in the middle of your palm, as if you were holding an imaginary apple.
When someone wants to communicate using the Polish manual alphabet, they would use a combination of these hand signs to spell out words and sentences. So if they wanted to say "Hello, my name is Anna," they would sign each individual letter until they spelled out the entire sentence.
It's like playing a game of charades with your hands! The Polish manual alphabet is a really cool way for people to communicate with each other without using words, and it's a big part of the deaf culture in Poland.
