Etymology: Auguste Piccard, the Swiss physicist, built the first bathyscaphe in the 1940s, and the vessel's name came from Greek roots meaning "deep boat." The word "bathyscaphe" is a French borrowing, and its first part, "bathy-", comes from the Ancient Greek "bathus," meaning "deep." The second part traces to "skaphē," a Greek term for a small boat or skiff, which is also the root behind English words like "scaphoid," the boat-shaped bone of the wrist. Because the vessel was a French invention in the mid-twentieth century, the word was coined from classical building blocks rather than handed down from antiquity. Ancient Greeks had no such device, so the term is a modern compound that borrows older vocabulary to name something entirely new. The plural "bathyscaphes" simply adds the English "-s" to the singular "bathyscaphe."
