This wordplay riddle asks: What kind of ring is square?
The answer is: a boxing ring.
Despite the name, a boxing ring is usually a square platform surrounded by ropes. The word “ring” here does not describe the shape of the area.
The clue is designed to make you picture a circular ring first, which makes the idea of a square ring sound impossible.
But once you think of sports instead of jewelry, the answer is simple.
This is a classic example of a riddle that relies on a familiar word having more than one meaning. A boxing ring is called a ring, even though its shape is square.
