Definition of the word spare part

The term "spare part" originally derives from the Anglo-Saxon word "spar," which meant "to save" or "to preserve." The word "spare" itself has been in use in the English language for more than a thousand years, primarily in the context of preserving something for future use. The term "spare part" specifically refers to a component that is kept on hand to replace a broken or malfunctioning part in a mechanical device or vehicle. The purpose of having spare parts on hand is to ensure that the device or vehicle can continue to operate even if a failure occurs, as opposed to being rendered completely dysfunctional until a new part can be sourced and fitted. The concept of spare parts dates back to ancient times, where provisions were made to keep extra components on hand for important devices like water pumps and windmills. The term "spare part" first appears in English language texts in the 1750s, with a reference to "spare pumps, which make no particular work, but yet are necessary" in Edward Cave's "Gentleman's Magazine" from 1754. Today, the term "spare part" is widely used in a variety of industries and contexts, including automotive, electronics, and construction. Being able to quickly and easily replace a broken part with a spare ensures a high level of reliability and minimizes downtime or disruption. The meaning of the term "spare part" has also expanded to include items like batteries and light bulbs, which are often replaced proactively to prevent future malfunctions.
