Have you ever paused while writing an email, article, or legal document and wondered whether to write wilful or willful? You’re not alone. This spelling confusion is common because both forms are correct and appear in dictionaries, making the choice tricky.
People search for wilful or willful to ensure their writing looks polished and professional, especially in formal or legal contexts. The confusion mainly comes from British vs. American English spelling differences.
The good news: once you understand the rules, the choice is simple. This article explains the meanings, origins, regional differences, common mistakes, and how to use willful or wilful confidently.
Wilful or Willful: Quick Answer
Both “wilful” and “willful” are correct spellings, but they are used in different varieties of English.
- Willful → Preferred in American English
- Wilful → Preferred in British English
Examples
- The employee’s willful neglect of duties led to termination. (American English)
- The damage was caused by wilful misconduct. (British English)
The meaning is the same in both cases: doing something intentionally, deliberately, or on purpose, often with a negative tone.
What Does Wilful / Willful Mean?
Both spellings describe an action done deliberately, not by accident. The word is often used when someone chooses to do something wrong, careless, or disobedient.
Common meanings include:
- Intentional behavior
- Deliberate disobedience
- Purposeful wrongdoing
Simple examples:
- She showed willful ignorance of the rules.
- His wilful behavior caused serious problems.
The word is especially common in legal, academic, and formal writing, where intention matters.
Origin:
The word comes from the Old English word “will”, meaning desire, intention, or choice. Over time, English writers added the suffix -ful, meaning “full of.”
So, wilful / willful literally means “full of will” or “acting with intention.”
Why two spellings exist
English spelling evolved differently in different regions:
- British English kept older spellings like wilful
- American English simplified spellings, leading to willful
This same pattern appears in other words, such as:
- Colour vs color
- Travelling vs traveling
British English vs American English
This is where most confusion about wilful or willful comes from.
Key difference
| British English | American English |
|---|---|
| wilful | willful |
Explanation
British English often drops one “l” in words ending with -ful, while American English keeps both “l” letters from the root word will.
Both spellings are grammatically correct within their regional standards.

Using the wrong spelling won’t usually change the meaning, but it can look unprofessional in formal documents.

| Mistake | Correct Form |
|---|---|
| Using both spellings in one document | Choose one and stay consistent |
