Picture a Roman facing a battlefield, a storm, or simply some alarming news: he might be trepidus, literally trembling with anxiety. Add Latin in-, meaning “not,” and the emotional weather suddenly clears—intrepidus is someone who is not trepidus. The word traveled through French as intrépide before entering English, preserving that neat bit of verbal engineering. Its nervous cousin survives in trepidation, while the opposite-looking intrepid describes explorers, soldiers, and anyone cheerfully walking toward danger. In 1966, Star Trek sent the USS Enterprise into the unknown; decades later, the fictional Intrepid class—best known through Voyager—gave this ancient Latin adjective a new set of starships to pilot.
