tenacious
adjective
Did you know?
Tenacious Has Latin Roots
For the more than 400 years that tenacious has been a part of the English language, it has adhered closely to its Latin antecedent: tenāx, an adjective meaning "holding fast," "clinging," or "persistent." Almost from the first, tenacious could suggest either literal adhesion or figurative stick-to-itiveness. Sandburs 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 tenāx led to the English word pertinacious, meaning "perversely persistent." You might use pertinacious for the likes of rumors and spam calls, for example.
