Did You Know?
If you say "pertinacious" out loud, it might sound familiar. That may be because if you take away the word's first syllable, you're left with something very similar to the word tenacious, which means "tending to adhere or cling." The similarity between "pertinacious" and "tenacious" isn't mere coincidence; both words derive from "tenax," the Latin word for "tenacious," and ultimately from the verb tenēre, meaning "to hold." Another descendant of "tenēre" is "tenure," a word that is typically used of the right to hold a job (especially a teaching position) for as long as desired.
