Definition

1. Noun:
   • A strap or set of straps on a horse's harness: A martingale is a piece of equipment that connects the noseband or reins to the girth or between the front legs. Its primary function is to prevent a horse from raising its head too high or throwing its head back.
   • A spar on a sailing vessel: In nautical contexts, a martingale is a short, fixed spar or strut extending downward from the bowsprit. It helps to support and control the tension on the jib-boom or other rigging.

Usage Examples

  • The rider adjusted the martingale to ensure better control of the horse's head carriage.
  • A running martingale gives the rider more leverage without being overly restrictive.

• Noun (Nautical):

Advanced Usage
