Definition of tarnish

The word "tarnish" has a fascinating history. It originated in the 14th century from the Middle English words "tarn" meaning "dirt" or "filth" and "ish" meaning "to make or become". Initially, "tarnish" meant to make something dirty or foul by introducing foreign matter or impurities. Over time, the meaning expanded to include the idea of causing something to lose its luster or shine, often due to exposure to air, moisture, or other environmental factors. In the 16th century, the word "tarnish" began to be used specifically to describe the oxidation that occurs on metal surfaces, leading to a dulling or discoloration. Today, the word is widely used in various contexts, from describing the tarnishing of metals to figuratively "tarnishing" one's reputation. Despite its evolution, the core idea remains: tarnish is the act of making something lose its original brightness or purity.
