How to sign

To sign "Secure" in American Sign Language (ASL), you combine the signs for "Safe" and "Save." For "Safe," make fists and cross them over your chest with palms facing you to form the letter "S." Then, separate your hands and turn your palms forward. For "Save," sharply tap the back of your non-dominant fist with the fingers of your dominant "V" hand.
