To sign the word “Charles,” use the American Sign Language (ASL) sign for the letter “C” by making a fist with your dominant hand and then extend your index finger while keeping the rest of the fingers curled. Then, use the ASL sign for the letter “H” by extending your index, middle, and ring fingers while keeping your thumb and pinky tucked in. Finally, bring your fingers together in front of your chest to form the letter “C” and then the letter “H.”
