What Does “Duel” Mean?
Duel means a fight or contest between two people.
Traditionally, a duel was a formal fight between two people, often using weapons. In older times, people might challenge each other to a duel because of an argument, insult, or serious disagreement.
Today, the word can also be used more generally for a competition or direct contest between two people or sides.
For example:

The main idea is always a direct contest or fight involving two opponents.
Dual vs. Duel: The Main Difference
The biggest difference is very easy:
Dual is about two things. Duel is about two opponents fighting or competing.
Consider these two sentences:
The car has dual airbags.
This means the car has two airbags or a system involving two airbags.
Now look at:
The two characters had a duel.
This means the characters had a fight or direct contest.
The words may sound similar, but they belong to different meanings.
Remember this rule
If you are talking about two parts, features, roles, purposes, or sides, use dual.
If you are talking about a fight or direct contest between two opponents, use duel.
