How to Sign "Bye" in American Sign Language (ASL)

Wave your hand with your palm facing out to say "bye" in ASL. You can choose to move your whole hand back and forth or just wiggle your fingers while keeping your palm still, and this simple gesture works well for saying goodbye to anyone in any situation. For a more formal way to say goodbye, touch your chin with your fingertips and then move your hand out and down in an arc. The regular wave probably came from how people naturally wave goodbye in many different cultures around the world. This common sign appears in two forms, but most people use the casual wave more often.
