How to Sign "Prove"
To sign 'prove', start with your non-dominant hand flat in front of you, palm facing up. Hold your dominant hand flat in front of your chest with the palm facing sideways. Bring your dominant hand down, rotating it so the back of your hand rests on your non-dominant palm, leaving both palms facing upwards.
Visual Logic(Etymology)
The sign for 'prove' is deeply rooted in the visual metaphor of presenting the truth. In American Sign Language, the open, upward-facing palm often represents openness, honesty, and things being brought to light. By bringing your dominant hand down to rest openly on your non-dominant hand, you are symbolically laying the facts out on the table for everyone to see. It visually communicates that the evidence is clear, undeniable, and presented without any hidden tricks or deception.
Signing Tips
When signing 'prove', focus on the contrast between the movement of your dominant hand and the stillness of your non-dominant hand. Your non-dominant hand acts as a solid, steady foundation, representing the established facts. Bring your dominant hand down with a deliberate, firm motion to convey certainty and confidence. The firmness of the landing can be adjusted to match the tone of your conversation—use a stronger movement for emphatic statements and a lighter touch for casual discussions about proof.
Common Mistakes
A frequent mistake beginners make when signing 'prove' is clapping their palms together, similar to the sign for 'school' or 'applause'. It is crucial to remember that the back of your dominant hand must land on the palm of your non-dominant hand. Both of your palms should be facing upwards at the end of the motion. Additionally, avoid moving both hands; your non-dominant hand should remain completely stationary as a base while only your dominant hand performs the downward movement.
Regional Variations
This sign is widely used and understood across the ASL community with minimal regional variation.

Frequently Asked Questions
Is 'prove' related to the sign for 'true'?

Yes, they are conceptually related! Both signs deal with certainty and facts. While 'true' typically starts at the lips to indicate spoken truth, 'prove' focuses on laying out the evidence openly on your hand to demonstrate that something is factual.

Does it matter how hard my hands hit together?

The intensity of the movement should match your intended meaning. For a casual conversation, a gentle landing is perfectly fine. If you are emphatically declaring that you will prove something, a firmer, more forceful landing will naturally convey that strong emotion.

Can I use this sign to mean 'evidence'?

Yes, 'prove' is often used to mean 'proof' or 'evidence' depending on the context of your sentence. Some signers may use an initialized version with an 'E' handshape for 'evidence', but the standard sign for 'prove' is widely understood for both concepts.
