What is s in sign language?

In American Sign Language (ASL), the letter "S" is signed by forming a fist with the dominant hand and sticking the thumb out to the side, similar to making the letter "A" but with the thumb extended. The non-dominant hand is used as a support near the chest or waist.

The sign for "S" is a simple and common letter used in fingerspelling and is utilized in many ASL words and signs. It is important to ensure that the thumb is clearly extended to indicate the letter "S."
