How to Sign "Outside" in American Sign Language (ASL)
In ASL, "outside" is signed by extending both hands with palms facing up, then moving them outward and away from the body in a sweeping motion. The sign shows open space. When talking about going outside or being outside, signers can change the movement a bit to match what they mean. This basic sign comes up all the time when people chat about weather or activities. The movement looks just like what it means.
