How to sign S in ASL

Letter S19 of 26Held still

Make a fist with your thumb wrapped across the front of your fingers.

Hold S steady for a moment, with your palm facing the person you're signing to.

Left-handed? Sign with your dominant hand; the shapes are the same, mirrored.

Don't mix it up

A: In A the thumb rests straight up along the side of the index finger; in S it wraps across the front of the fingers.
T: In T the thumb pokes up between the index and middle fingers; in S it lies across the front of the fist.

Make the handshape and hold it. Turn on your camera and it checks your handshape as you go. The video stays on your device.

S is in Letters S–Z. ASL a Day brings it back tomorrow to sign from memory, then again just before you'd forget. Five minutes a day.
