Synonyms and Adversary, Antagonist, Opponent, Enemy, Foe. These words vary in strength according as they express spirit, action, or relation. A foe has most of the spirit of enmity, or is actively hostile. The word is more used in poetry than in prose. Enemy, as denoting an opponent in war, or a member of an opposing party, does not necessarily imply personal hostility. Opponent, adversary, and antagonist are less severe in their opposition, and need have no animosity. Opponent is often a passive word; antagonist is always active and personal. A man may be our opponent in an argument or a lawsuit, our adversary in a game, as chess, our antagonist in a wrestling- or boxing-match, or other occasion of strenuous exertion: the choice between the three words depends chiefly upon the measure of activity involved. In the Bible, adversary covers the meaning of all five words.
