Open
In short
Open refers to a type of tournament in sports, such as golf or tennis, where any player is allowed to enter regardless of their professional status.
In plain words
It is a competition with no restrictions on who can sign up. While famous professionals usually play, amateur players can also join the field if they meet certain criteria.
A simple example
The British Open in golf allows players from all over the world to compete. Even if a player is not a top-ranked professional, they can try to qualify for the event.
Why it matters
It keeps sports inclusive and provides a pathway for unknown talent to prove themselves. It also allows fans to see how amateurs compare to the world's best.
Easy to mix up
Do not confuse it with a 'closed' championship, which is only for members of a specific club or top-ranked professionals.
