How to Sign "Fall" in American Sign Language

The short answer: it depends on which "fall" you mean

English uses one word for two different ideas, but American Sign Language (ASL) uses two different signs. If you mean the season (autumn), you brush one flat hand down the forearm of your other arm, like leaves dropping from a tree. If you mean the action of falling down, a two-finger "legs" handshape stands on your other palm and then tips over. Choosing the wrong one changes your meaning, so decide which idea you need before you sign.

This guide covers ASL, the sign language most widely used in the United States. Other sign languages, such as British Sign Language, use different signs, and ASL itself has regional and individual variation. The descriptions below follow commonly taught forms; no source material or demonstration video was supplied for this article, so check your signing against a video from a reputable ASL dictionary or a Deaf ASL instructor.

How to sign "fall" as the season (autumn)

Think of your non-dominant arm as a tree trunk and your dominant hand as leaves falling from it. Your dominant hand is the one you write with; your non-dominant hand acts as the base.

• 1. Raise your non-dominant forearm in front of your body, bent at the elbow, so it angles upward like a tree trunk. Keep that hand relaxed and open.
• 2. Form a flat hand with your dominant hand: fingers together and straight, thumb alongside. In ASL this is called a B handshape.
• 3. Bring the index-finger edge of your dominant hand to the upper part of your raised forearm.
• 4. Brush it downward along the forearm toward the elbow.
• 5. Repeat the brushing motion, typically twice, with a light, smooth movement.

How to check it worked: your raised arm stays still the whole time, only your dominant hand moves, and the motion travels down toward your elbow rather than up toward your wrist. If someone watching can picture leaves sliding down a trunk, the shape is right.

How to sign "fall" as in falling down

This sign shows a person losing their footing. Two fingers represent the legs, and your other palm is the ground.

• 1. Hold your non-dominant hand flat, palm facing up, in front of your body. This is the ground.
• 2. Make a V handshape with your dominant hand: index and middle fingers extended and spread, other fingers folded down.
• 3. Point the two fingertips down so they "stand" on your flat palm, like legs.
• 4. Flip the V over in one quick movement so the fingers land on their backs on the palm, as if the person has fallen.

How to check it worked: the V starts upright on the palm and ends lying on it, and the movement is a single decisive tip rather than a slow slide. A crisp start and end position makes the meaning clear.

Quick comparison

Meaning | Dominant hand | Base hand | Movement

Fall (autumn, the season) | Flat B handshape | Forearm raised and angled like a tree trunk | Brushes down the forearm toward the elbow, usually twice

Fall (to fall down) | V handshape, fingertips down | Flat palm facing up | V stands on the palm, then flips over to lie on it

Limitations and next steps

• Phrases such as "fall asleep" or "fall in love" are separate concepts in ASL and are not formed by combining these signs; look them up individually.
• Written steps cannot show speed, rhythm or facial expression, which also carry meaning in ASL. A video demonstration is the most reliable way to confirm your form.
• If you are unsure which sign a situation calls for, fingerspelling F-A-L-L is an understandable fallback, though the dedicated signs are more natural.
• If you sign on a video call, keep both hands and the raised elbow inside the camera frame, because the season sign depends on movement down to the elbow.
