Definition of tamper

The word "tamper" stems from the Middle English word "tAMPEREN," which was derived from the Old French word "tamper," meaning "mix or blend." It referred to agitating or altering something's composition by adding another substance to it. Initially, the term "tamper" was associated with the process of mixing ingredients during the preparation of medicinal remedies, as well as winemaking and other similar chemical processes. The usage of "tamper" to mean an instrument or device used for mixing or manipulating materials dates back to the early 19th century. In the context of engineering and mechanics, "tamper" came to mean a tool used to exert force to tighten or compress parts or seals, typically in mechanical or industrial equipment, in order to enhance performance or prevent leakage. Today, the meaning of "tamper" has expanded to include any action or intentional or careless intervening in a system, process, or machine, to alter its normal function or performance, and could result in hazardous or unexpected consequences. As such, tampering is considered a safety and legal concern in various fields, and is often addressed through regulatory measures and workplace procedures. The term "tamper-proof" is sometimes used to describe mechanisms and devices that are designed to discourage or prevent accidental or intentional tampering, such as child safety caps or anti-theft devices.
