How to Sign "Kniw"
To sign 'know', form your dominant hand into a flat shape with your fingers together, then bend it slightly at the knuckles. Bring the tips of your fingers to tap the side of your forehead. The motion is a simple, direct tap to the head, representing knowledge stored in the mind.
Visual Logic(Etymology)
The sign for 'know' is highly iconic, as it points directly to the brain—the center of thought, memory, and knowledge. By tapping the forehead, you are visually indicating that the information is stored in your mind.
Signing Tips
Keep your fingers together and your thumb resting alongside your index finger. The tap should be gentle and placed on the upper side of your forehead, near the temple. Ensure your palm is facing downward or slightly inward toward your face as you make contact.
Common Mistakes
A common mistake is using a single index finger instead of the whole flat hand, which changes the meaning to 'think'. Another mistake is tapping the cheek or chin instead of the forehead, which can confuse the sign with other vocabulary.
Regional Variations
This sign is widely used and understood across the ASL community with minimal regional variation.
