A tourney is a medieval-style competition or contest. Imagine knights fighting with swords and shields.
When people talk about a tournament, they usually mean a sporting event where teams or individuals compete against each other in a specific activity like archery, jousting, or fencing. In the United States, for example, you might hear about the Kentucky Horse Show as a sort of tourney. It's not just about the horses; it's also about the riders and their skills. Some events at the show could be thought of as individual tournaments within the larger competition.
