Opponent is a person who opposes or disagrees with something. Proponent is a supporter or advocate of an idea or cause.

Key Differences

An opponent is someone who actively disagrees with or resists a particular idea, policy, or approach. In contrast, a proponent is a person who supports or advocates for a specific idea, policy, or method, often speaking out in its favor.
In a debate, an opponent argues against a particular point of view, presenting counterarguments or opposing evidence. A proponent, on the other hand, defends the view, providing arguments and evidence in support of the position.
In the context of sports or games, an opponent is a competitor who is trying to win against others. Conversely, a proponent is not relevant in such competitive contexts but is more involved in supporting or promoting certain principles or activities.
An opponent can be found in various areas like politics, where they oppose policies or candidates. A proponent in politics is someone who endorses specific policies, candidates, or political ideologies.
In legal terms, an opponent could be a lawyer who represents the opposing side in a court case. As for a proponent, they might be a legal advocate who argues in favor of a particular interpretation of the law or a legal decision.
