How to Sign "Lock"

Form both hands into "S" shapes (closed fists). Hold your non-dominant hand horizontally in front of your body with the palm facing down. Place your dominant fist on top of the back of your non-dominant hand, and twist your dominant wrist forward so its palm turns to face down, mimicking the motion of turning a key.

How to Sign "Lock"
Form both hands into "S" shapes (closed fists). Hold your non-dominant hand horizontally in front of your body with the palm facing down. Place your dominant fist on top of the back of your non-dominant hand, and twist your dominant wrist forward so its palm turns to face down, mimicking the motion of turning a key.
Visual Logic(Etymology)
The sign for 'lock' is highly iconic and visual. The non-dominant fist represents the stationary object being locked, such as a door or the base of a padlock. The dominant fist represents the key or the top of the padlock, and the twisting motion directly mimics the physical action of securing it.
Signing Tips
Keep your non-dominant hand completely steady as a base. The movement should only come from the wrist of your dominant hand twisting, exactly like you are turning a stiff key in a deadbolt. Ensure both hands are tightly closed in 'S' shapes to clearly convey the concept of something being secured.
Common Mistakes
A common mistake is moving both hands during the sign. Remember that the bottom hand represents the stationary lock or door, so it should stay completely still. Another mistake is using loose hands instead of firm fists, which can make the sign look sloppy.
Regional Variations
This sign is widely used and understood across the ASL community with minimal regional variation.

Frequently Asked Questions
What is the difference between the signs for 'lock' and 'key'?

While they are related, 'key' is typically signed by holding an imaginary key with an 'X' handshape and twisting it into the open palm of your non-dominant hand. 'Lock' uses two full 'S' handshapes (fists) stacked on top of each other.

Can I use this sign for a combination lock?

Yes, this sign is used for the general concept of locking something, regardless of the specific lock type. However, if you are specifically describing the action of dialing a combination, you might mime turning a small dial with your fingers instead.

Does it matter which way I twist my hand?

Yes, the standard movement is to twist your dominant hand forward so the palm ends up facing down. Twisting it backward might look like you are trying to unlock it, though the actual sign for 'unlock' usually involves twisting and pulling the hands apart.
