how to sign the word ablock

To sign the word “ablock,” use one hand to make a fist with the thumb extended upward and resting on top of the fist. The other hand should be flat with the palm facing downward, and it should be placed on top of the knuckles of the fist. Then, move both hands in a circular motion, as if they are turning a key in a lock. This gesture signifies the concept of “blocking” something.
