This gesture (reconstructed by me) corresponds to the sign tevir ("broken"). In the Letteris and Ginsburg Editions the sign appears as a curved line with a dot to the left; in manuscripts and other printed editions, the line is straight.

Since one dot in a written or printed superlinear sign consistently corresponds to one digit of the hand in the corresponding gesture, it is reasonable that the dot in
tevir corresponds to a digit also. Rather than having a finger trace first a line, then a dot, it is reasonable that the line represents a flat palm like that corresponding to merkha, and the dot a digit. In terms of ease of production, that digit is most likely the thumb rather than a finger.
