What does tenacious mean?
Tenacious describes someone or something that holds firmly, persists despite difficulty, or refuses to give up. Its most common use is complimentary: a tenacious researcher keeps working through obstacles, while a tenacious negotiator maintains a position until a resolution is reached. The word can also carry a slight negative implication when it suggests stubbornness, excessive persistence, or reluctance to release something. In physical contexts, tenacious describes roots, tendrils, insects, or materials that cling or grip firmly. The adjective is useful because it combines the ideas of holding on and continuing to act, giving it a stronger and more evocative tone than simply saying persistent. It is common in professional, journalistic, scientific, and literary writing, and it is readily understood in both British and American English.
