Tenacity is the quality of being persistent, determined, and resilient in the face of challenges or obstacles. It refers to the ability to hold onto a goal or pursue something with unwavering determination, even when faced with difficulties or setbacks.

Interesting fact: The word “tenacity” is derived from the Latin word “tenax,” which means “holding fast” or “clinging.” This etymology perfectly captures the essence of the word, as it emphasizes the idea of holding onto something tightly and not letting go.
