Word Confusion: Adversary vs Enemy vs Foe vs Opponent

Posted March 30, 2023 by Kathy Davie in Author Resources, Self-Editing, Word Confusions, Writing

This word confusion adversary vs enemy vs foe vs opponent actually is a follow-on from
antagonist (as a writing tip) and an exploration of antagonist vs protagonist (as a word confusion).

And all five words mean the same thing. They all mean opposition, some of it hostile in all instances and other times hostile in certain situations, such as court, politics, or games.

Naturally, this being English, there are nuances:

  • Adversary – may not be an enemy; may engage in a friendly competition
  • Enemy – has contempt for the other and wants to harm them; does not engage in friendly competitions
  • Foe – the antonym of friend, someone who used to be your friend
  • Opponent – someone who is against your beliefs or is the other side in a team or group

Word Confusions . . .

. . . started as my way of dealing with a professional frustration with properly spelled words that were out of context in manuscripts I was editing as well as books I was reviewing. It evolved into a sharing of information with y’all. I’m hoping you’ll share with us words that have been a bête noire for you from either end.
