Other forms: caprioles; caprioling
A capriole is a playful jump or leap. In dressage, it's an advanced leap that a highly trained horse performs.
While performing a capriole, a horse jumps straight up into the air, pulling its front legs in toward its chest, and kicking its back legs out parallel to the ground. This classical — and very impressive! — equestrian feat probably evolved from techniques that warhorses were trained to do in medieval times. The word capriole comes from the Italian word capriolare, which means "to leap like a goat." It is often used to describe leaping about joyfully, as a child or a young goat might do. In ballet, a graceful, leaping capriole — more often spelled as cabriole — is an energetic, kicking leap.
