How to sign D in ASL

Letter D4 of 26Held still

Point your index finger up; touch your thumb to the tips of your other curled fingers.

Hold D 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

X: X bends the index finger into a hook; D keeps it straight, with the thumb touching the other fingers.
Z: Z starts from a pointing index finger with the other fingers closed, then draws a Z in the air; D stays still, with the thumb touching the middle fingertip to make a circle.

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

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