Wilful or Willful Comparison Table

Simple rule: Use willful when writing American English. Use wilful when following a British spelling convention that prefers the single-l form.

What Does Wilful or Willful Mean?

Wilful or willful describes behavior that is intentional, deliberate, or stubborn.

The word comes from will, which relates to personal intention, desire, or determination.

Depending on the context, it can describe an action performed knowingly or a person who refuses to change their mind.

1. Deliberate or Intentional Actions

One common meaning is doing something intentionally rather than accidentally.

When an action is described as willful, it often suggests that the person acted knowingly.

Examples:

• The employee was dismissed for willful misconduct.
• The company investigated allegations of wilful negligence.
• His willful refusal to follow instructions caused problems.
• The manager reported a wilful violation of workplace rules.

In these sentences, the word emphasizes deliberate behavior.

However, legal definitions can be more specific than everyday meanings.

2. Stubborn or Strong-Willed Behavior

Wilful or willful can also describe someone who insists on doing things their own way.

Examples:

• The willful child refused to follow the teacher’s instructions.
• Her wilful attitude made teamwork difficult.
• He remained willful despite repeated warnings.
• The wilful teenager insisted on making his own decisions.

Here, the word describes stubbornness or resistance to advice.

3. Strong Personal Determination

Sometimes, the adjective suggests independence or determination.

Examples:

• The willful character challenged traditional expectations.
• Her wilful personality made her difficult to influence.
• His willful nature helped him resist social pressure.

Although the word can suggest determination, it often carries a negative tone when that determination becomes unreasonable.

Wilful or Willful: American English Spelling

In American English, willful is the preferred spelling.

It is commonly used in American dictionaries, academic materials, business communication, legal documents, and everyday writing.

Examples of Willful in American English

• The employee committed a willful violation of company policy.
• His willful behavior created unnecessary difficulties.
• The investigation revealed willful misconduct.
• She showed willful disregard for safety instructions.
• The child became increasingly willful as he grew older.

These examples use the standard American spelling with two consecutive letters l.

Why Does American English Prefer Willful?

English spelling conventions developed differently in various regions.

Over time, willful became the dominant spelling in the United States.

The spelling also retains the double l found in the root word will.

For American audiences, willful is generally the safest and most familiar choice.

Wilful or Willful: British English Spelling

In British English, wilful is a traditional spelling.

It appears in British literature, formal writing, historical texts, and legal terminology.

However, willful is also recognized in British English. The preferred form may depend on the dictionary, publisher, or editorial style guide.

Examples of Wilful in British English

• The court examined evidence of wilful misconduct.
• His wilful refusal delayed the investigation.
• The student displayed wilful disobedience.
• The company faced allegations of wilful negligence.
• Her wilful behaviour frustrated the entire team.

These sentences demonstrate the traditional British spelling.

Is Willful Incorrect in British English?

No. Willful is not automatically incorrect in British English.

Both forms are recognized, although wilful has a strong association with traditional British spelling.

The important rule is consistency.

If your publication uses wilful, continue using that form throughout the document unless you are quoting a source that uses another spelling.

Wilful or Willful in Legal Terms

Wilful or willful frequently appears in legal language.

In some legal contexts, proving willfulness requires more than showing that a rule was broken.

Courts apply specific legal standards when determining whether willful blindness has been established.
