To oppose something is to go against it or fight hard to stop it. A senator might oppose a bill, or a teen might oppose authority.

Words starting with opp-, like opposite, opponent, and oppose, usually hint that there's a disagreement somewhere. You might oppose a decision if you don't agree with it or if it's the opposite of what you believe or know is right. Sometimes, though, to oppose just means to be on the other team.
