Learn It

Start with the simple version, then practice it with real signs.

A headshake is one of the clearest ways to show negation in ASL.

The head moves side to side while the face looks negative, usually with a small frown or furrow.

The movement does not need to be huge. It should be clear enough to see and easy enough to hold while your hands sign.

Practice the positive version first, then sign the same idea again with a headshake.

If your hands say LIKE and your head shakes no at the same time, the meaning can become do not like.

For beginners, think: hands show the action, headshake changes the action to negative.

Side to sideNegation uses a side-to-side headshake, not a nod.
Negative faceUse a small frown or focused furrow so the sentence reads as no or not.
Same signs, new meaningThe same manual signs can change meaning when the headshake is added.

Try It

Practice slowly. Make the face before the sentence is over.

  1. Sign with a calm face. Then sign with a headshake.
  2. Sign with a calm face. Then sign with a headshake.
  3. Sign with a calm face. Then sign with a headshake.
  4. Sign with a calm face. Then sign with a headshake.
  5. Sign with a calm face. Then sign with a headshake.
  6. Sign with a calm face. Then sign with a headshake.

Common Mistake

Do not add the headshake only after the signs are finished. If the headshake comes too late, the viewer may read the signs as positive first.

Deeper Note

A little more grammar

The technical source explains that ASL can mark negation without a separate manual sign like NOT. The useful beginner rule is simple: the headshake must cover the signs you are making negative.
