How to Sign “Sister”

  1. Start with your dominant hand in the shape of the letter “S”. To do this, make a fist with your thumb resting on the outside of your fingers.
  2. Position your hand near your chin, with your palm facing inwards towards your face.
  3. Move your hand outward slightly from your chin while keeping the “S” shape. This movement should be gentle and smooth.
  4. Maintain a friendly facial expression, as this adds to the meaning of the sign and shows warmth in your communication.

Common Mistakes

  • Not positioning the hand close enough to the chin can make the sign unclear.
  • Using a flat hand instead of the “S” shape can lead to confusion with other signs.
