Visual Logic(Etymology)
The sign for 'can' is highly iconic of strength, power, and ability. The 'S' handshapes represent solid fists, which are visually associated with capability and firmness. The decisive downward motion reinforces the idea of certainty, showing that something is possible or that you have the power to accomplish a task.
Signing Tips
When signing 'can', the movement should be a sharp, decisive downward flick of the wrists. This firm motion conveys ability and certainty. Make sure your hands stay in the 'S' shape (like making a fist with your thumb wrapped across the front) throughout the entire sign. Keep your elbows relatively still so the movement is isolated to your wrists.
Common Mistakes
A common mistake beginners make is moving their entire arms up and down instead of just flicking their wrists. Remember to keep your arms steady and let your wrists do the work. Another mistake is using 'A' handshapes (thumb resting on the side of the index finger) instead of the correct 'S' handshapes (thumb wrapped across the front of the fingers).
Regional Variations
This sign is widely used and understood across the ASL community with minimal regional variation.

Frequently Asked Questions
Is this sign used for a tin can, like a can of soup?
No, this sign is only used for the verb 'can', meaning ability or permission (like 'I can do it'). For a physical tin can or soda can, you would use a completely different sign that outlines the shape of a cylinder.
Do I need to use both hands for this sign?
Yes, 'can' is a two-handed sign. Both hands should form the 'S' handshape and move simultaneously in a downward flick. Using only one hand might confuse the meaning or look like a mistake.
How do I sign 'cannot' or 'can't'?
To sign 'can't', you do not use the 'can' sign. Instead, you strike the index finger of your dominant hand downward across the extended index finger of your non-dominant hand. It is a completely different motion!
