The word "tenacity" traces back to the Latin tenax, meaning "holding fast," which itself comes from tenēre (to hold). Over time, the suffix -acity was added to form a noun denoting the quality of being tenacious. The evolution reflects a shift from the literal act of holding to the abstract notion of persistence or stubbornness.
