exclusive
Limited to certain people and not shared with others.
Exclusive means limited to a particular group or not shared with others. When a country club is exclusive, it carefully chooses who can join, often keeping most people out. When a clothing store carries an exclusive design, you won't find that item anywhere else. The word suggests something special or restricted that not everyone can access.
In journalism, an exclusive is a story that only one reporter or news organization has, at least at first. Landing an exclusive interview with the president or a famous athlete is a big achievement because no other journalist gets the same access.
The word also describes things that cannot exist together. If two activities are mutually exclusive, you must choose one or the other because doing both is impossible. Going to a soccer game and attending your friend's birthday party at the same time are mutually exclusive if they happen at the exact same hour.
Notice how exclusive can create a sense of specialness or privilege, but it can feel either positive or negative depending on the situation. An exclusive summer program for talented musicians might inspire students to work harder. But a school lunch table that's exclusive, where certain kids refuse to let others sit down, just creates unnecessary hurt feelings and loneliness.
