Edge Of A Sumo Ring
Last Moment, Critical Moment
noun
Remember how 土俵 is a sumo ring? Now you're at its edge, which means this is the edge of a sumo ring. This can also refer to a last moment or critical moment in time, like the moment before you get pushed out of the ring.
This combines the on'yomi readings in the 土俵 vocab with the kun'yomi reading you learned from the 際 vocab. Just think of these as two familiar vocab words mashed together and you should be good to go!

The sumo wrestler braced himself at the edge of the ring and was able to throw his opponent out.
