What does opponent mean?
An opponent is a person, group, force, or position that stands against another in a competition, disagreement, conflict, or challenge. The word is especially common in sport, where it identifies the person or team being played against, but it is also used in politics, debate, law, business, and everyday discussion. An opponent need not be an enemy: competitors in a friendly match are opponents, and an opposing argument may be described as a formidable opponent. The term is generally neutral and often implies a clearly defined contest, though it can suggest that the other side is actively resisting or seeking to prevent success. Understanding “opponent” is useful because it captures both competition and opposition, while leaving open whether the relationship is hostile, strategic, or simply formal.
nounA person or group that opposes another person, group, plan, or idea. In a contest or dispute, an opponent is the person or side being challenged or competed against.
- A person who competes against another in a game, match, contest, or competition.
- A person, organization, or force that opposes another person, group, viewpoint, plan, or action.
- A person or thing that makes a particular outcome difficult or unlikely.
"The champion defeated her strongest opponent in the final."
"She carefully studied her opponent’s previous matches before the tournament."
"The proposed development met fierce opposition from local residents."
The regular plural is “opponents.”
"The two opponents agreed to meet before the championship."
An opponent is not merely someone who disagrees: in a contest, an opponent is the person you must outwit, outlast, or outplay.

Etymology of opponent
The word comes from Latin opponere, formed from op- and ponere, meaning “to put against” or “to set opposing.” English borrowed the form through Old French opponent, originally a participle meaning “opposed” or “put against.” The related words oppose, opposed, opposite, and opposition developed from the same Latin elements. Over time, opponent came to be used especially for a person who contests another in a competition or dispute.
