How to Sign "Begun"
To sign 'begun' (which is the same sign used for 'begin' or 'start'), hold your non-dominant hand open in front of you with your fingers together and your palm facing your dominant side. Take your dominant hand and extend your index finger. Place your dominant index finger between the index and middle fingers of your non-dominant hand, and twist it outward as if you are turning a key in an ignition.
