Did you know?

For the more than 400 years that tenacious has been a part of the English language, it has adhered closely to its Latin antecedent: tenax, an adjective meaning "tending to hold fast." Almost from the first, tenacious could suggest either literal adhesion or figurative [stick-to-itiveness](https://www.merriam-webster.com/dictionary/stick-to-itiveness). [Sandburs](https://www.merriam-webster.com/dictionary/sandbur) are tenacious, and so are athletes who don't let defeat get them down. We use tenacious of a good memory, too—one that has a better than average capacity to hold information. But you can also have too much of a good thing. The addition in Latin of the prefix per- ("thoroughly") to tenax led to the English word [pertinacious](https://www.merriam-webster.com/dictionary/pertinacious), meaning "perversely persistent." You might use pertinacious for the likes of rumors and telemarketers, for example.
