Don't Be Afraid to Learn About Intrepid

If you’re going to name a ship, whether an aircraft carrier or an interstellar starship, you could do worse than to name it the Intrepid, as both the United States military and Star Trek writers have done, respectively. (Technically “Intrepid” is a class of Trek ships that includes the Voyager, etc., but you get the drift.) Intrepid, after all, comes from the Latin word intrepidus, itself formed by the combination of the prefix in-, meaning “not,” and the adjective trepidus, meaning “alarmed.” When not designating sea or space vessels, 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 couch surfer endeavored to watch every installment of the beloved sci-fi series in chronological order.” Intrepid word lovers may be interested to know of the existence of trepid, meaning “fearful”; it predates intrepid but most are too trepid (or simply unaware of its existence) to use it.
