You need not be afraid to find out the origins of today's word, although its history does include fear. Intrepid derives from the Latin word intrepidus, itself formed by the combination of the prefix in- (meaning "not") and trepidus, meaning "alarmed." Other relatives of trepidus in English include trepidation and trepidatious, as well as trepid (which actually predates intrepid and means "fearful"). Synonyms for intrepid include courageous, valiant, fearless, valorous, and simply brave. Intrepid aptly describes anyone—from explorers to reporters—who ventures bravely into unknown territory, though often you'll see the word loaded with irony, as in "an intrepid volunteer sampled the entries at the pie bake-off."
