Many English learners feel confused when they see words like dualling, duelling, and dueling. They look almost the same, but are they correct? Do they mean the same thing? Why do some versions have one “l” and others have two?
This spelling difference is not just a small detail. It can affect your writing in exams, academic essays, business communication, and international contexts. Understanding the difference between these words will help you write more accurately and confidently.
Understanding the Base Words
Before comparing the spellings, let’s look at the base verbs:
- Duel – a formal fight between two people, traditionally with weapons.
- Dual – meaning “two” or “double.”
Although they sound similar, duel and dual have completely different meanings.
Duel (related to fighting)
A duel is a fight between two people, often arranged formally.
The two knights agreed to duel at sunrise.
Dual (meaning two)
Dual describes something that has two parts or aspects.
She has dual citizenship in Canada and France.
Now let’s examine how this connects to duelling, dueling, and dualling.
Duelling vs. Dueling
Duelling and dueling come from the verb to duel (to fight formally). The only difference is spelling style.
British English: Duelling
In British English, when adding “-ing” to verbs that end in a single vowel + consonant, we often double the final consonant.
The two politicians were duelling in a heated public debate.
American English: Dueling
In American English, the final “l” is usually not doubled.
The movie shows two warriors dueling with swords.
Meaning
Both words mean exactly the same thing: fighting or competing in a duel.
Dualling – A Different Word
Dualling is different. It comes from the word dual, not duel.
In British English, dualling often refers to making something “dual,” especially roads.
The government announced the dualling of the highway to reduce traffic congestion.
Here, dualling means converting a single carriageway into a dual carriageway (a road with two separate lanes for opposite directions).
In American English, this concept is usually expressed differently:
The state plans to expand the highway into a divided highway.
Americans rarely use the word dualling in this context.
Side-by-Side Comparison
| Word | Base Word | Meaning | Used In |
|---|---|---|---|
| Duelling | Duel | Fighting in a duel | British English |
| Dueling | Duel | Fighting in a duel | American English |
| Dualling | Dual | Making something double (often roads) | Mainly British English |

Why Does the Spelling Change?
The difference between duelling and dueling follows a general spelling rule.
British English Rule
British English usually doubles the final “l” before adding “-ing” or “-ed.”
- travel → travelling

- duel → duelling
American English Rule
American English often keeps a single “l.”
- travel → traveling
- cancel → canceling
- duel → dueling
This is a consistent spelling difference between the two varieties of English.
