How to Sign "Grandson"
To sign *grandson*, start by bringing your dominant hand to your forehead, pinching your thumb and fingers together as if grasping the brim of a baseball cap—this is the sign for *boy*. Next, open your hand so your fingers are straight and your thumb is extended. Move your hand outward from your forehead in a small forward arc to represent 'grand', and then continue bringing it downward to your lower chest area, completing the motion for *son*.
