• Axel — A highly difficult jump in figure skating, named after Norwegian skater Axel Paulsen, characterized by being the only jump that takes off from the forward outside edge of the skate and lands, after one or more aerial rotations, on the backward outside edge of the opposite skate. Due to the forward takeoff, executing an axel always includes an extra half-rotation compared to the base number of revolutions.
