How to Sign "Knew"

To sign 'knew,' you use the base sign for 'know.' Form your dominant hand into a flat shape with your fingers together and straight. Bring your hand up and tap your fingertips gently against the side of your forehead. In ASL, past tense is usually established by context or a time sign at the beginning of the sentence, so the sign itself remains the same.

Visual Logic(Etymology)
In American Sign Language, the location of a sign often provides a strong visual clue about its meaning. Signs related to the mind, cognitive processes, thoughts, and knowledge are almost always located near the head or forehead. By tapping the forehead with a flat hand, the sign for 'knew' visually represents information, awareness, or knowledge being held securely inside the brain. This iconic placement helps learners easily group and remember mental verbs like know, think, memorize, and forget.
Signing Tips
When expressing concepts like 'knew' in ASL, remember that you don't need to change the verb itself to show past tense. Instead, establish the timeframe at the beginning of your sentence by using a time marker, such as signing 'yesterday,' 'last week,' or 'past.' Once the time is set, simply use the standard sign for 'know' by tapping your flat hand against your forehead. Maintaining a clear, confident handshape will make your signing much easier to read.
Common Mistakes
A frequent mistake beginners make is using a single index finger to point at the head, which is actually the sign for 'think' or 'wonder.' To clearly sign 'knew,' make sure to keep all four fingers flat and together. Another common error is placing the hand too low on the face, such as near the cheek or chin. Ensure your fingertips are tapping the upper side of your forehead. Finally, avoid tapping too forcefully; a gentle double tap or single touch is perfect.
Regional Variations
This sign is widely used and understood across the ASL community with minimal regional variation.

Frequently Asked Questions
Do I need to sign 'past' every time I sign 'knew'?

No, you only need to establish the past tense once in your conversation or at the beginning of your sentence. Once the timeframe is understood by the person you are talking to, you can just use the base sign for 'know' without repeating the time marker.

Is the sign for 'knew' different from 'know'?

No, they use the exact same handshape and movement! ASL does not conjugate verbs by changing their spelling or base movement like English does. Instead, context or specific time signs indicate that the action happened in the past.

Can I use my non-dominant hand to sign this?

You should always use your dominant hand for one-handed signs like 'knew'. If you are left-handed, use your left hand to tap your forehead; if you are right-handed, use your right hand. Consistency helps make your signing clear and natural.
