Quick Definition
Tenacious (adjective) describes a person who holds firmly to a purpose, belief, or course of action and refuses to give up, even when it is difficult. It can also describe a very tight grip or something hard to remove.
Example: "She was tenacious in her search for answers and never gave up."
What Does Tenacious Mean?
The word tenacious comes from the Latin tenax, meaning "holding fast," which in turn derives from tenere, "to hold." It entered English in the early 17th century. The literal sense — holding on tightly — still survives in phrases like "a tenacious grip" or "tenacious roots."
In modern English, tenacious most often describes character: a determined, persistent person who keeps pursuing a goal long after others would give up. It is a high-value word in journalism, business, and sport. You will see it in phrases like "a tenacious defender," "tenacious in pursuit," and "sheer tenacity."
Key point: tenacious is usually a compliment, suggesting admirable willpower. But applied to unwanted things — a "tenacious cough" or a "tenacious stain" — it simply means stubbornly persistent and hard to get rid of.
