This is how you sign Decide in American Sign Language.

Description

To sign "Decide" in American Sign Language (ASL), extend your index finger and touch the tip to your right forehead momentarily. While still touching your forehead, transform your hand from an extended index finger into an "F" handshape (thumb and index finger extended, other fingers closed). Simultaneously with step 2, raise your non-dominant hand into an "F" handshape near your waist. Then, with both hands in "F" shapes, move them down a short distance in a decisive motion. At the end of the downward movement, stop both hands abruptly with fingers pointing down slightly.
