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

In ASL, "smart" is shown by tapping your finger on your temple or forehead. The movement is quick and happens once or twice, with your finger touching your head in a clear way. This sign came from people thinking the brain is where intelligence comes from. You can tap harder or softer to show how smart you mean. People use this sign in schools, at work, and when talking with friends, and it's a common way to show intelligence. When you want to tell someone they're smart, you usually smile and raise your eyebrows while making the sign.
