Humor vs humour is a common spelling comparison because both forms are correct, but they belong to different varieties of English. The word describes amusement, comedy, a sense of what is funny, and in some contexts a person’s mood or temperament.
Humor is the standard spelling in American English. Humour is the standard spelling in British English and other varieties that generally follow British spelling conventions. The meaning and pronunciation are essentially the same, so the correct choice depends mainly on the variety of English you are using.
Quick Answer
Use humor in American English.
Use humour in British English.
For example:
She has a great sense of humor. , American English
She has a great sense of humour. , British English
Both spellings refer to the same general idea. The main difference is the regional spelling convention.
Why People Confuse Them
The confusion comes from the extra u in humour.
American English commonly uses shorter spellings in several words that traditionally contain -our in British English. This creates pairs such as:
- humor / humour
- honor / honour
- color / colour
- favor / favour
Because both humor and humour are widely used and pronounced essentially the same way, readers may wonder whether one spelling is incorrect.
The answer is no. Both are established spellings, but they belong to different regional conventions.

| Noun | Yes | Yes |
| Verb | Yes | Yes |
| Pronunciation | Generally the same | Generally the same |

Meaning And Usage Difference
The basic meanings of humor and humour are the same.
The word can describe:
- something funny
- the quality of being amusing
- a person’s ability to appreciate or express comedy
- a mood or temperament
- the act of indulging or accommodating someone when used as a verb
For example:
The movie has a lot of humor.
The movie has a lot of humour.
The meaning does not change when the spelling changes.
The word also appears in the common phrase:
She has a great sense of humor.
In British English:
She has a great sense of humour.
Tone, Context, And Formality
Neither spelling is inherently more formal, more humorous, or more sophisticated than the other.
The choice depends on the variety of English used in the surrounding text.
For American readers:
The article uses humor to explain a difficult subject.
For British readers:
The article uses humour to explain a difficult subject.
The important point is consistency. A document written in American English should normally use humor, while a document following British spelling should normally use humour.
The pronunciation is generally the same, so this is primarily a spelling distinction.
Which One Should You Use?
| Context | Best Choice | Why |
|---|---|---|
| American English | humor | Standard US spelling |
| US school assignment | humor | Matches American spelling |
| US business writing | humor | Consistent with US English |
| British English | humour | Standard British spelling |
| British publication | humour | Matches British conventions |
| Mixed international audience | Follow the chosen style | Consistency matters |
If you are writing for a US audience, choose humor.
If you are writing in British English, choose humour.
When One Choice Sounds Wrong
The two spellings usually do not sound different when spoken. The problem appears in writing when a text mixes regional spelling systems without a clear reason.
For example, a document that consistently uses American spellings such as color and favor will usually look inconsistent if it suddenly uses humour.
Likewise, a British English document that uses colour, favour, and honour will normally use humour rather than humor.
This is a consistency issue, not a difference in meaning.
