verb play boisterously
originOriginated in the United States in 1793, as cauvaut, applying to horses, probably from the colloquial intensifying prefix ca-/ka- + vault (“jump, leap”); later generalized. Early sources connect it to cavault, a term for a certain demeanor of horses. Alternatively, a variation of curvet.
