If you've ever watched the Tour de France on television, you've seen the peloton, the brightly colored pack of riders making up the central group. You may have also gained some inadvertent insight into the word itself, which as you may have guessed is French in origin. In French, "peloton" literally means "ball," but it is most often used with the meaning "group." It's frequently used in the bicycling context, just as in English, but it can also refer to a group in a marathon or other sporting event. French peloton can also mean "squad" or "platoon," and since we’ve told you that you probably won’t be too surprised to learn that it is also the source of our word platoon.
