If you are unsure whether humour or humor is correct, the short answer is: both are correct. The difference is mainly regional spelling. Humour is the standard spelling in British English, while humor is the standard spelling in American English. Cambridge and Oxford both identify humour as the British form and humor as the American form.
This small spelling difference matters when you are writing for a particular audience. Choosing the appropriate form can make your English look consistent and professional, especially in academic papers, business documents, websites, publishing, and formal communication.
In this guide, you will learn the difference between humour and humor, when to use each spelling, how their related forms change, whether one is more correct, how to remember the difference, and which version you should choose in American, British, Canadian, and other varieties of English.
Quick Answer: Humour or Humor?
Humour and humor have the same meaning and pronunciation. The main difference is regional spelling:
- Humour = British English
- Humor = American English
Examples
- British: She has a great sense of humour.
- American: She has a great sense of humor.
- British: The film is full of humour.
- American: The movie is full of humor.
Memory tip: Think of British English = extra “u”. The same pattern appears in words such as colour/color, favour/favor, and honour/honor.
The key point is simple: neither spelling is a misspelling. Choose the form that matches the variety of English you are using.
What Does Humour or Humor Mean?
Humour/humor is a noun referring to the quality that makes something funny or amusing, or the ability to recognize and appreciate things that are funny. It can also refer to a person’s general ability to make others laugh or see the amusing side of a situation.
For example:
His sense of humour makes difficult meetings more enjoyable.
This means that his ability to recognize or create amusing moments makes the meetings more pleasant.
The word can also describe a particular style of comedy:
The novel uses dark humour.
Here, humour refers to a type or quality of comedy.
There is another, less common meaning. In formal or older usage, humour can refer to a person’s mood or state of mind:
He was in an ill humour.
Oxford lists this meaning as a formal use, while its historical meaning refers to the four bodily liquids once believed to influence a person’s health and character.
Key takeaway
In modern everyday English, humour/humor usually means something funny, the quality of being funny, or the ability to appreciate or create comedy.
Humour vs. Humor: The Main Difference
| Feature | Humour | Humor |
| Standard variety | British English | American English |
| Meaning | Same | Same |
| Pronunciation | Essentially the same | Essentially the same |
| Formal writing | Correct | Correct |
| American publications | Usually not preferred | Preferred |
| British publications | Preferred | Usually not preferred |
| Canadian English | Commonly used | Also encountered depending on style |
| Related adjective | humorous | humorous |
The important distinction is spelling, not meaning.
For example, a British writer might say:
The speaker used humour to keep the audience engaged.
An American writer would normally write:
The speaker used humor to keep the audience engaged.
Neither writer has changed the meaning. They have simply followed different spelling conventions.
Why does the spelling matter?
It matters because consistency is an important part of polished writing. If an American document uses humor, color, and favor, suddenly using humour can make the writing look inconsistent. Likewise, a British publication that otherwise follows British spelling would normally use humour.
Practical rule
Do not choose the spelling based on which one looks more correct. Choose it based on your intended variety of English.
Is Humour British or American?
Humour is the British spelling. Humor is the American spelling.
Cambridge explicitly identifies humour as the UK spelling of humor, while its American dictionary entry identifies humor as the US spelling of humour.
Oxford gives the same distinction by listing humor as US English and humour as British English.
This follows a broader pattern in English spelling.
Compare:
| British English | American English |
| humour | humor |
| colour | color |
| favour | favor |
| honour | honor |
| behaviour | behavior |
| neighbour | neighbor |
There are exceptions to spelling patterns, so you should not assume every British-American difference works in exactly the same way. However, humour/humor follows the familiar British -our versus American -or pattern.
Key takeaway
If your audience is primarily in the United Kingdom, use humour. If your audience is primarily in the United States, use humor.
Humorous or Humourous: Which Is Correct?
A common mistake is to assume that if British English spells the noun humour, the adjective must therefore be humourous.
It is not.
The standard adjective is:
humorous
This spelling is used in both British and American English.
Examples:
- She wrote a humorous article.
- The speaker gave a humorous presentation.
- It was a humorous response to a serious question.
Oxford defines humorous as meaning funny or showing a sense of humour. Merriam-Webster likewise defines humorous as characterized by or expressing humor.
So the correct forms are:
- humour — British noun
- humor — American noun
- humorous — adjective in both varieties
Common mistake
❌ The article was very humourous.
✅ The article was very humorous.
The spelling humourous is generally not the standard form you should use in modern standard English.
Humour, Humor, and Humorous: Related Forms
Understanding the word family makes the spelling easier to manage.
| Word | British English | American English | Part of speech |
| Noun | humour | humor | Noun |
| Adjective | humorous | humorous | Adjective |
| Adverb | humorously | humorously | Adverb |
| Noun describing quality | humorousness | humorousness | Noun |
| Verb | humour | humor | Verb |
The verb has a different meaning from the usual noun.
To humour/humor someone means to go along with their wishes or behavior, often to keep them happy or avoid an argument. Oxford gives the British humour and American humor forms for this verb.
For example:
I don’t agree with his idea, but I’ll humour him.
American English:
I don’t agree with his idea, but I’ll humor him.
This does not mean “make him laugh.” It means to indulge or accommodate him.
Expert tip
When editing, always check whether humour/humor is being used as a noun or a verb. The meaning changes with context, even though the spelling distinction remains regional.
How Do You Pronounce Humour and Humor?
The two spellings are generally pronounced the same.
The first part sounds like “hyoo”, followed by a sound similar to “mer” in American pronunciation.
Oxford and Cambridge provide pronunciation information for both forms.
For practical purposes, English learners do not need to change their pronunciation simply because they change from humour to humor.
Why is pronunciation useful?
This is particularly helpful when listening to British and American speakers. You may hear the same word while seeing two different spellings in written English.
For example:
- Written British: humour
- Written American: humor
- Spoken: essentially the same word
Memory tip
The extra “u” is mainly a spelling signal, not a pronunciation signal.
When Should You Use Humour?
Use humour when following British English spelling conventions.
It is appropriate for:
- British school assignments
- UK academic writing
- British newspapers and magazines
- UK business communication
- British websites
- Writing for a British audience
- Publications that use British style
Example:
The author uses dry humour to discuss modern workplace culture.
If the rest of your document uses British spellings such as organisation, colour, and centre, humour is the natural choice.
Practical guidance
If you are writing for an institution, publisher, employer, or website, follow its established style guide rather than mixing regional conventions.
When Should You Use Humor?
Use humor when following American English spelling conventions.
It is appropriate for:
- US school assignments
- American academic writing
- US business communication
- American newspapers and magazines
- American websites
- Writing primarily for a US audience
Example:
The presenter used humor to make the technical subject easier to understand.
If your document uses organization, color, and center, then humor will normally fit the same spelling system.
Practical guidance
For a US-focused website, consistency usually matters more than trying to accommodate every English-speaking country in the same article.
What About Canadian, Australian, and Other English?
English spelling is not divided into only two categories.
Different English-speaking regions use their own conventions, and individual publishers or organizations may establish specific style preferences.
For example, Canadian English commonly retains many British-style spellings, although Canadian usage also contains American influences. Australian and New Zealand English likewise tend to follow British spelling conventions in many cases.
That means you should not automatically assume:
“Not American = always British.”
Instead, check the style expected by your audience or organization.
Best approach for international websites
If you operate a website intended for readers around the world, decide which spelling system your editorial policy follows.
For example:
- US-focused site → humor
- UK-focused site → humour
- International site using British conventions → humour
- International site using American conventions → humor
The important thing is to avoid randomly switching between the two.
Humour or Humor in Academic Writing
Both forms can be correct in academic writing. The appropriate choice depends on the English variety required by your institution, professor, journal, publisher, or style guide.
Consider these examples:
British English:
The study examines the role of humour in political communication.
American English:
The study examines the role of humor in political communication.
Neither sentence is grammatically wrong.
What students should do
Before submitting an assignment, look at the spelling conventions used throughout the course materials. If your university specifies a particular style, follow it.
More importantly, do not switch spelling systems halfway through an essay.
A paper containing humour, color, organization, and behavior may look poorly edited because it combines different conventions.
Key takeaway
Academic correctness involves more than choosing a dictionary-approved spelling. Follow the required regional and institutional style consistently.
Humour or Humor in Business and Professional Writing
In professional writing, regional spelling can signal attention to detail.
Suppose a British company publishes this sentence:
Our campaign combines clever humour with clear product information.
That spelling fits its audience.
An American company might write:
Our campaign combines clever humor with clear product information.
Again, both are correct.
Professional editing tip
For large documents, create a simple style checklist before editing. Decide whether you are using:
- British or American spelling
- British or American punctuation conventions where relevant
- Consistent terminology
- Consistent capitalization
- Consistent date and measurement formats
This prevents individual words such as humour/humor from becoming isolated inconsistencies.
Common Mistakes With Humour and Humor
Mistake 1: Thinking one spelling is wrong
❌ Humour is incorrect because American English uses humor.
✅ Both are correct.
Why it happens: American English is common in international digital content, so learners may see humor more often.
How to avoid it: Identify the English variety before judging the spelling.
Mistake 2: Mixing spellings
❌ The organization used humour in its marketing campaign and changed the color of its logo.
This may be inappropriate if the document is intended to follow a consistent American or British style.
✅ American: The organization used humor in its marketing campaign and changed the color of its logo.
✅ British: The organisation used humour in its marketing campaign and changed the colour of its logo.
Mistake 3: Writing “humourous”
❌ It was a humourous story.
✅ It was a humorous story.
Why it happens: Writers sometimes add the British -our pattern to every related form.
How to avoid it: Remember that the adjective is humorous in both major spelling systems.
Mistake 4: Assuming humour means only “a joke”
A joke can contain humour, but humour has a broader meaning. It can describe a person’s ability to appreciate comedy, the funny quality of a situation, or a particular style of comedy.
A Simple Decision Guide: Which One Should You Choose?
Use this quick framework when editing:
Are you writing for a primarily American audience?
→ Yes: Use humor.
Are you writing for a primarily British audience?
→ Yes: Use humour.
Are you writing for another English-speaking audience?
→ Check the organization’s or publication’s preferred style.
Are you writing for an international audience?
→ Choose one spelling system and use it consistently.
Are you unsure whether “humourous” is correct?
→ Use humorous.
One-line rule
US English → humor. British English → humour. Adjective → humorous.
Does Humour Mean the Same as Comedy?
Not exactly.
These words overlap, but they are not perfect synonyms.
Humour/humor refers broadly to the quality of being funny or the ability to recognize and express what is amusing.
Comedy usually refers to a form, genre, performance, or type of entertainment designed to amuse.
For example:
The comedy was full of clever humor.
Here, comedy describes the entertainment, while humor describes one of its qualities.
Other related terms include:
- wit — clever and often quick verbal humor
- sarcasm — often ironic language used to mock or criticize
- satire — humor or irony used to expose or criticize people, ideas, or institutions
- irony — expression in which the intended meaning differs from the literal or expected meaning
- amusement — pleasure caused by something entertaining or funny
Merriam-Webster distinguishes these terms by their particular functions and shades of meaning.
Why this distinction matters
Calling every humorous statement “comedy” can make your writing less precise. In professional or academic contexts, choosing the more exact term improves clarity.
The History Behind the Word
The spelling difference has a much older story than modern British-versus-American English.
Merriam-Webster traces humor through Middle English humour and Anglo-French forms to Latin humor, meaning “moisture.”
Historically, humors referred to bodily fluids. Ancient and medieval medical theories associated four bodily fluids with health, temperament, and personality. Over time, the word developed meanings connected with a person’s disposition or mood and eventually acquired its modern sense relating to amusement and comedy.
This history explains why older expressions can use humour in ways that seem unrelated to comedy today.
For modern writers, however, the historical background is mainly useful for understanding why the word has several related meanings.
