The rump or hindquarters of a horse; the area of the horse's body behind the saddle.
From Old French 'croupe,' from Old German 'kruppa.' The term has been used in English since medieval times to describe equine anatomy, particularly in the context of horsemanship and saddle placement.
Croupe is why we say a horse is 'well-grouped' when it has good hindquarters—and it's also why 'tycoon' comes from Japanese, yet 'croupe' comes from German via French, showing how horse terminology traveled across Europe!
