Usage: When tenacious first entered the English language in the early 1600s, it meant almost exclusively to hold fast or adhere. Sir Isaac Newton used it to describe substances that stick to other substances, while Cowper used it to describe the suction of clay. Today it may be used to describe one who is obstinate or stubborn, holding fast to opinions or ideas. It can also signify persistence, as with a tenacious lawyer who rarely loses a case due to her argumentative skills.
Suggested Usage: You're tenacious, aren't you? You might think so, since tenacious is often used (or misused) as a compliment. "His tenacious grip on the basketball" makes perfect sense, but "his tenacious appetite"? Not so much. When you use it, frame it as a compliment, even if you don't mean it to be. "Your baby certainly is tenacious!" you might say to the proud new mother. Before her smile fades, make sure you tell her that she owes you for the iPod he wouldn't let go of.
Etymology: As with many words in use in the English language, tenacious has its roots in Latin. The word tenax or tenacis in Latin is derived from the verb tenere, which means "to hold." Similar words such as tenable have the same root. Tenacious was first recorded in English usage around 1607 and, as mentioned above, has been used for hundreds of years in a very similar way contextually to how it is used today.[/FONT]
