means a horse breed developed by crossing hot-blooded breeds like thoroughbreds with calm, heavy cold-blooded breeds, aimed at sport disciplines like dressage and show jumping.

from the term comes from european breeding programs, mostly in germany and the low countries, that spent centuries crossing fiery thoroughbreds and arabians with stolid draft-type farm horses to get power and brains in one package, then formalized the results into studbooks named after regions rather than one animal.
