How to Sign "Brief"
To sign 'brief,' form both hands into 'H' handshapes, with your index and middle fingers extended and kept together. Hold your non-dominant hand in front of you with the fingers pointing sideways across your body. Place the fingers of your dominant 'H' hand on top of the non-dominant fingers. Quickly slide your dominant hand off the non-dominant hand. This quick, brushing motion perfectly captures the idea of something being short in duration or happening very fast.
