Pronunciation: [kɹˈʌpə] (IPA) 
The word "crupper" is spelled with a silent "p" at the end, which can be confusing for those unfamiliar with its pronunciation. It is phonetically transcribed as /ˈkrʌpər/. The "cr" is pronounced with a hard "k" sound, followed by a short "ʌ" sound and the "p" is silent. A crupper is a piece of saddle equipment that fits around a horse's tail to prevent the saddle from sliding forward.
A crupper refers to a strap or loop that is attached to the back of a horse's saddle and secured under the tail to prevent the saddle from sliding forward. It is specifically designed to stabilize the saddle by anchoring it over the horse's hindquarters, thereby preventing it from slipping forward and creating discomfort or potential harm to both the animal and the rider. Typically made of leather or synthetic material, the crupper is attached to the back of the saddle with one end threaded through a ring or buckle and then passed under the horse's tail. The strap is adjustable to accommodate different horse sizes and shapes.
The purpose of a crupper is to enhance the stability and balance of the saddle, particularly when riding on uneven terrain, jumping obstacles, or engaging in activities that require sudden movements or changes in speed. By securing the back end of the saddle, it helps distribute the rider's weight more evenly and prevents the saddle from shifting forward and potentially causing injury to the horse's back or discomfort to the rider. The crupper provides an additional form of security and support, enabling the rider to maintain better control and balance during various equestrian activities. Overall, the crupper plays a vital role in ensuring the safety, comfort, and optimal performance of both horse and rider.
• To put a crupper on.
• A strap of leather buckled to a saddle, and which, passing under the horse's tail, prevents the saddle from slipping forward on to the horse's neck.

The word "crupper" has its roots in Middle English and Old French. It can be traced back to the Old French word "croppiere", which referred to a strap or loop attached to the back of a horse's saddle to keep it from sliding forward. This term was derived from the Middle English word "cropp", meaning "hump" or "bump", which ultimately comes from the Old Norse word "kroppr". The term "crupper" has been used since the 14th century to describe the strap or loop, as well as the part of a horse's harness that passes under its tail to prevent the saddle from slipping forward.
