Etymology

Origin of monopolize

First recorded in 1605–15; monopol(y) + -ize

Explanation

If you monopolize something, you won't let anyone else get their hands on it. When you were little, your mom might have said, "Don't monopolize the swing. Let your sister have a turn." When a company monopolizes something, it has an unfair amount of control over a particular product or service, hurting other companies and giving consumers fewer choices. A business might monopolize the media in an entire state, for example, by owning the local newspapers, TV stations, and news websites. Monopolize comes from monopoly, which isn't just a great board game, but actually means "exclusive control of a commodity or trade."
