Wilful and willful are both correct spellings, but the preferred form depends on the variety of English you are using. Wilful is the traditional British spelling, while willful is the standard American spelling.
Both words describe something done deliberately, intentionally, or stubbornly, often despite knowing that it is wrong or against a rule. For example, “His wilful refusal to cooperate caused problems” is standard British English, while “His willful refusal to cooperate caused problems” is standard American English.
The main difference is the spelling of the word, not its meaning. This distinction can be confusing because many British words ending in ful keep a single l, while American English often uses willful with two l’s. In this guide, you will learn the meaning, origin, British and American spellings, common mistakes, everyday examples, and the best form to use in different types of writing.

Definition and Meaning of Wilful and Willful
What Does Wilful or Willful Mean?
Wilful or willful describes something that is done intentionally or deliberately. It can also describe someone who stubbornly refuses to obey, cooperate, or change their behavior.
The word can have a neutral meaning when it simply means intentional, but it often carries a negative sense.
For example:
- “The damage was wilful.”
- “His wilful disobedience led to disciplinary action.”
- “She made a willful decision to ignore the warning.”
The exact tone depends on the context.
Simple Meaning of Wilful orWillful
In simple English, wilful/willful means:
done deliberately
or
intentionally refusing to do what is expected
For example:
“He ignored the warning on purpose.”
This could be described as:
“His action was wilful.”
The word is especially common in formal, legal, professional, and serious contexts.
Wilful or Willful as a Description of a Person
The word can also describe a person who is determined to do what they want, even when others advise against it.
For example:
“She is a wilful child.”
This can mean that she is stubborn, independent, or difficult to control.
The tone depends on context. In some situations, wilful can suggest strong determination, while in others it suggests stubborn disobedience.
The Origin of Wilful and Willful
Wilful and willful come from the English word will, referring to intention, desire, or determination.
The suffix ful means “full of” or “characterized by.”
The word has been used in English for centuries to describe actions or behavior guided by conscious intention or personal determination.
The spelling later developed differently in British and American English.
British English generally retained:
wilful
American English commonly adopted:
willful
The difference is therefore connected to spelling conventions rather than two different meanings.
British English vs American English Spelling
The main spelling difference is the number of l’s.
British English
The preferred British spelling is:
wilful
Example:
“His wilful disobedience was clearly documented.”
American English
The preferred American spelling is:
willful
Example:
“His willful disobedience was clearly documented.”
The meaning remains the same.
This is similar to other British and American spelling differences, where the same word may appear in slightly different forms depending on the variety of English being used.
Why Does British English Use “Wilful”?
British English traditionally spells the word as wilful, with one l before ful.
This follows the common British spelling of many words formed with the suffix ful.
Examples include:
- useful
- careful
- hopeful
- meaningful
- wilful
The spelling wilful is well established in British English and is especially common in British legal, academic, and formal writing.
Why Does American English Use “Willful”?
American English commonly uses willful, with two l’s.
The spelling emphasizes the connection with the word will.
For example:
will + ful = willful
This spelling is standard in American dictionaries and is common in American legal, business, academic, and everyday writing.
The important point is that willful is not a spelling mistake simply because British English uses wilful.
Both forms are legitimate.
Which Spelling Should You Use?
Choose the spelling based on your audience and the variety of English you are following.
For British English
Use:
wilful
Example:
“The court found that the damage was wilful.”
For American English
Use:
willful
Example:
“The court found that the damage was willful.”
For International Writing
If your audience includes readers from different English speaking regions, either spelling can be understood.
However, consistency is important. If your document follows British English, use wilful throughout. If it follows American English, use willful throughout.
Do not switch between the two forms randomly in the same piece of writing.
Common Mistakes with Wilful vs Willful
Mistake 1: Calling Wilful Incorrect
Some writers assume wilful is a spelling mistake because willful has two l’s.
That is incorrect.
Wilful is a standard British English spelling.
Mistake 2: Calling Willful Incorrect
Similarly, willful is not incorrect simply because British English uses wilful.
It is the standard American spelling.
Mistake 3: Mixing Both Spellings
Using wilful in one paragraph and willful in another can make your writing look inconsistent.
Choose one spelling according to your preferred variety of English and use it consistently.
Mistake 4: Confusing Wilful with Willing
Wilful does not simply mean “willing.”
Willing means ready or prepared to do something.
Wilful/willful usually means deliberate or intentional and can suggest stubbornness or wrongdoing.
For example:
“She was willing to help.”
“She showed wilful disregard for the rules.”
These sentences express very different ideas.
