Definition of spur

The word "spur" originally derives from the Old French word "espurre," meaning "spur" in English. This French word is believed to have come from the Vulgar Latin word "studera," which itself developed from the Latin word "ustibulum," meaning "heel" or "ankle band." The Latin word "ustibulum" originated from the Roman word for "lower part of the body," which was "sub," meaning "under," and "pila," meaning "ball" or "round thing." The Roman use of this term referred to a type of leather strap worn around the ankle or heel of a shoe, often decorated with a round or oval-shaped object, such as a stylized animal head or other decorative feature. In medieval Europe, this leather strap became a popular accessory for horseback riding, as it helped to prevent the rider's feet from slipping out of the stirrups during battle or other athletic pursuits. The French word "espurre" became anglicized to "spur" in Middle English during the 14th century, and it has remained in use in the English language ever since. In modern English, the word "spur" refers not only to the actual metal or plastic tips attached to the end of a rider's spurs but also more broadly to any incentive, encouragement, or motivator that prompts someone to take action or work harder. The idea behind this usage is that a rider might be prodded or "spurred on" by the threat or promise of a reward or challenge, just as a horse might be encouraged to move forward by the pricking sensation of a spur.
