Sign Language Night: How to Sign "Night" in ASL

The short answer

In American Sign Language (ASL), the sign for "night" is commonly taught like this. Hold your non-dominant arm across your body, roughly level, with the palm facing down. Bend the fingers of your dominant hand forward with the palm facing down, then tap the wrist of that hand on the back of your non-dominant wrist. The movement is often described as the sun dipping below the horizon, with your flat forearm as the horizon.

Two things can change this answer. First, sign languages are not universal. ASL is used in the United States and parts of Canada, and other sign languages, including British Sign Language and Russian Sign Language, use different signs. If you searched in Russian because you need Russian Sign Language, this guide does not cover that sign. Second, "sign language night" can also mean a social event where people meet to practice signing. If that is what you need, look for local Deaf community organizations or sign language classes. This guide covers the sign itself.

Step by step

• 1. Decide which hand is dominant. This is usually the hand you write with. Either side is correct as long as you stay consistent.
• 2. Make the horizon. Bring your non-dominant forearm across the front of your body at about chest height, roughly parallel to the floor, palm down.
• 3. Shape your dominant hand. Keep the fingers together and bend them forward at the knuckles, so the hand looks like a flat hand folded over. The palm faces down.
• 4. Place it. Rest the wrist of your dominant hand on the back of your non-dominant wrist so your bent fingers point down past the far side of your forearm.
• 5. Move. Tap your dominant wrist on the non-dominant wrist. Many teachers show a small double tap for the noun "night".

Common mistakes

• Fingers spread apart instead of held together.
• Fingers pointing up or straight ahead, which loses the sense of the sun setting.
• Dominant hand resting on the elbow or mid-forearm instead of near the wrist.
• Non-dominant arm tilted steeply, so it no longer reads as a horizon.
• No facial expression. In ASL, facial expression carries grammar and tone, so a neutral or relaxed face fits a plain statement better than a frozen one.

Related phrases

"Good night" is commonly signed as GOOD followed by NIGHT. "Tonight" is commonly signed as NOW followed by NIGHT. Regional and personal variations exist, so treat these as common forms rather than the only correct ones.

Checking the result

Written descriptions leave room for error in handshape, position and movement. Compare your version against a video from a reputable ASL dictionary or a Deaf instructor. Feedback from a fluent signer is the most reliable check.

Recording yourself also helps. A camera preview that opens only confirms that the browser or system has camera access. Recording a short clip and playing it back confirms that video is actually being captured, and lets you check the sign clearly. When you review the clip, check these points:

• Framing: both hands, both forearms and your face are fully in view. Signs near the chest are easy to cut off with a close, face-only crop.
• Lighting: your hands are lit from the front. Strong light behind you can turn your hands into silhouettes.
• Background: a plain physical background that contrasts with your skin and clothing makes handshapes easier to read.
• Virtual background or blur: call effects can smear or clip moving hands at the edges, so turn them off if hand detail matters.
• Mirroring: many apps mirror your self-view but send an unmirrored image to others. Judge your signing from a recorded clip or another person's view, not only the mirrored preview.

Limitations

No source material was supplied for this guide, so the description above reflects how the ASL sign is commonly taught and has not been checked against a specific dictionary entry. It does not cover regional ASL variants or other national sign languages. Confirm the sign with video from a trusted ASL resource or a fluent signer before relying on it in conversation.
