Sign "Understand?"
To sign the question, "Do you understand?" make the
hand sign for "understand" while making the facial
expression for a yes/no question. The hand sign
begins by making an O-letter shape with your palm
towards your forehead. Then pop your index finger
up as though a light bulb is going on. To make the
yes/no question facial sign, tilt your head slightly
forward and raise your eyebrows.
