Baseball teams in the U.S.A. have their own secret hand signs. A coach on the sideline may touch his hat, pat his knee, or rub his nose to send a message to a player on the field.
People who are deaf use sign language every day. They use their hands and faces to make signs that stand for words or ideas. They also spell out words by shaping letters with their fingers.
You probably already know a few signs yourself. How do you say “Good-bye,” “Okay,” and “Stop!” without making a sound? What other signs do you use or see?
People who are, deaf and blind can learn to feel what people say if words are finger-spelled into their hands.
