The word "stamina" originates from Latin stamen (plural stamina), meaning "thread" or "fiber," metaphorically representing the "threads of life" or vital energy. In Roman mythology, the Fates spun the stamina (threads) of human lives. Over time, it evolved to signify endurance, reflecting the idea of resilience woven into one’s constitution. The modern sense of "physical/mental endurance" emerged in the 17th century, retaining the core metaphor of inner strength as a durable thread.
