Dual vs. Duel: What’s The Difference?

English has many words that sound the same, but are spelled differently and mean different things. These words are called homophones. Some homophones are spelled nearly the same, too, which does nothing to add clarity to the situation.

Dual and duel are two such homophones. Their pronunciations and spellings are very close, which can make knowing whether to use dual or duel difficult.

Luckily, once you know the difference, choosing between them is simple.

In this article, I will compare dual vs. duel, and I will use each in a sentence to illustrate how they work. I’ll also explain a helpful trick to remember when to use each word.

When to Use Dual

A doctor, for instance, might say of a patient who has two diseases,

When to Use Duel

duel definition and dual definitionWhat does duel mean? Duel can be a noun or a verb.

As a noun, it refers to a conflict between two entities, but may or may not imply violence. Here are some examples:

  • Aaron Burr challenged Alexander Hamilton to a duel.
  • The candidates were wrapped up in their duel for the White House.
  • Beatrice and Benedick were engaged in an ongoing duel of wits.
  • There was no other way for this championship — which morphed into one of the most epic final-round duels the sport has ever seen — to end. –New York Post

As a verb, duel means to engage in a conflict between two entities. Again, the conflict is not necessarily violent. Here are two examples:

  • We will duel in the town square at high noon.
  • I would duel her in chess, but I would probably lose.

While duel can be a synonym for verbs like battle or argue, duel should only be used when the battle or argument is between two parties. Two swordsmen can duel, for example, but if three or more swordsmen are fighting, it is more accurate to choose a different word instead.
