opponent in conflict or competition
A person or group you fight, compete, or argue against.
Usage pattern:
[someone]'s adversary in [a conflict or competition]
Common mistake:
Learners often use "enemy" when "opponent" or "adversary" would be better. "Enemy" can sound too strong in neutral contexts like sports or business. Also, learners sometimes confuse the noun "adversary" with the adjective "adversarial" (e.g., saying *"he is my adversarial"* instead of "he is my adversary" or "our relationship is adversarial"). Finally, "adversary" is more formal than "opponent" and is less common in casual speech.
Synonyms
opponent (More common in everyday language and especially in sports or debates; slightly less formal than "adversary".)
|
enemy (Suggests stronger hatred or hostility, often in war or deep personal conflict.)
|
rival (Focuses on competition, especially for the same goal or position, and may be less hostile than "adversary".)
Antonyms
ally (An ally supports you in a conflict instead of opposing you.)
|
friend (A friend is someone on your side in life, not someone who stands against you.)

the Devil or Satan (religious)
In some religions, another name for the Devil or Satan, seen as the great enemy of God and good things.
Usage pattern:

Synonyms
Satan (A proper name used mainly in Christian and related religious texts; essentially the same figure as "the Adversary" in this sense.)
|
the Devil (The most common English term for this figure in general religious and cultural contexts.)
Antonyms
