Humour or humor are both correct spellings of the same English noun. The spelling humour is standard in British English, while humor is standard in American English. Both refer to the quality of being amusing, the ability to recognize what is funny, or something intended to entertain. The difference is regional spelling, not meaning.
Have you ever written the word humour or humor and stopped because you could not remember which spelling was correct? You are not alone. English has many words that change spelling depending on whether the writer follows British or American conventions, and this is one of the most familiar examples.
Humour and humor have the same meaning. Both can describe something funny, a person’s ability to appreciate jokes, or a particular style of comedy. The only major difference is the spelling convention used by the writer.
British English normally uses humour, while American English uses humor. This distinction matters in academic writing, publishing, professional communication, websites, and international content because inconsistent spelling can make otherwise polished writing look careless.
Understanding the difference is therefore less about memorizing a complicated grammar rule and more about recognizing which variety of English your audience expects.
Humour vs Humor: What’s the Difference?

Quick Recap

The difference is spelling rather than grammar.
Your choice should match your audience and overall English style.
Is Humour vs Humor a Grammar, Vocabulary, or Usage Issue?
This is primarily a spelling and regional usage issue.
There is no meaningful grammatical distinction between the two forms. A British writer does not use humour because the sentence has a different grammatical structure. The extra letter simply reflects British spelling conventions.
Likewise, an American writer does not use humor because the word has a different definition. American spelling simply removes the u.
Consider these two sentences:
She has a great sense of humour.
She has a great sense of humor.
Both sentences communicate exactly the same idea.
The first follows British spelling conventions. The second follows American spelling conventions.
Are They Interchangeable?
In meaning, yes.
In spelling style, you should choose according to your target variety of English.
A British newspaper would normally use humour. An American newspaper would normally use humor.
An international website may choose either form, but it should establish a consistent editorial style.
Formal vs Informal Usage
Neither spelling is more formal than the other.
Humour is not inherently more sophisticated, and humor is not inherently more casual.
A formal British research paper can use humour. A formal American research paper can use humor.
The same principle applies to informal conversation.
Academic vs Casual Usage
Academic writers should follow the spelling conventions specified by their university, publisher, journal, or style guide.
If the publication uses British English, humour is generally appropriate.
If it uses American English, humor is generally appropriate.
The most important principle is consistency. Switching between British and American spelling without a reason can distract readers and create an impression of poor editing.

When You Should NOT Use Humour or Humor
The biggest problem is not choosing the supposedly wrong word. It is failing to maintain a consistent spelling system.
Here are several situations where writers should be careful.
1. Do Not Mix British and American Spellings Randomly
If an article uses humour, colour, and favour, suddenly using humor can make the spelling inconsistent.
2. Do Not Assume Humor Is Always Correct
American spelling is not the universal standard for English.
3. Do Not Assume Humour Is More Correct
British spelling is not inherently more grammatically accurate.
4. Do Not Treat the Words as Different Meanings
They have the same basic meaning.
5. Do Not Change Spelling Without Considering Your Audience
A British reader expects British conventions in many contexts, while an American reader generally expects American conventions.
6. Do Not Ignore a Publication Style Guide
Professional publishers often specify the spelling variety that writers must follow.
7. Do Not Switch Between Humor and Humour in One Article
Unless you are deliberately discussing regional differences, one spelling should normally be used throughout.
8. Do Not Confuse Humor With Humorous
Humor and humour are nouns. Humorous is the adjective.
For example:
The story contains humor.
The story is humorous.
The grammatical roles are different.

Humour and Humor in Modern Technology and AI Tools
Modern technology has made the concept of humor particularly interesting because computers increasingly interact with human language.
Artificial intelligence systems can generate jokes, identify humorous language, analyze sentiment, and examine patterns in comedic writing. Natural language processing systems may also attempt to determine whether a particular sentence is intended seriously or humorously.
The spelling still depends on the English variety.
An American technology company might write:
Our AI system can detect humor in conversational text.
A British organization might write:
Our AI system can detect humour in conversational text.
The technology is the same. The regional spelling changes.
This distinction is useful for content creators working with AI because generated text can sometimes mix American and British spelling. If your website uses British English, you may want to check AI generated content for unwanted American spellings.
The same applies in reverse for an American publication.
The Etymology of Humour and Humor
The word has a long history.
Humour entered English through French and ultimately traces back to the Latin word umor, meaning moisture or fluid.
In ancient and medieval medical thinking, bodily fluids were associated with different physical and emotional conditions. These were known as the bodily humors.
Over time, the meaning expanded beyond medicine. The word became associated with a person’s temperament or disposition.
Eventually, the modern sense connected with amusement, comedy, and the ability to recognize what is funny became established.
The spelling diverged as English developed different regional conventions.
British English retained the u in humour, while American English generally adopted humor.
The same broad spelling difference appears in words such as colour and color, favour and favor, and labour and labor.
An Expert Style Insight
“When regional spellings carry the same meaning, the strongest editorial choice is the one that matches the audience and remains consistent throughout the document.”
This principle is especially valuable for writers producing content for international audiences.
Two Practical Case Studies
Case Study 1: A British Educational Website
Imagine a British educational website publishing an article about comedy in literature.
The article uses terms such as colour, behaviour, and favour throughout the page.
The natural choice is:
Humour plays an important role in the novel.
Using humor in the middle of the article would introduce an American spelling into an otherwise British English environment.
The issue isn’t comprehension. British readers will understand both forms. The concern is editorial consistency.
Case Study 2: An American Technology Company
Now consider an American software company publishing a guide about conversational AI.
Its documentation uses American spellings such as behavior, color, and favorite.
The natural sentence would be:
The system is designed to understand humor in customer conversations.
Using humour would not change the meaning, but it would create a spelling inconsistency within the company’s documentation.
These examples demonstrate why localization and editorial consistency matter even when the underlying vocabulary is identical.
