If you are writing for a US audience, humor is the spelling you usually want. Humour is also a real word, but it is the British and Commonwealth spelling.
That means the choice is not about meaning. It is about the type of English you are using. A student in the United States should write sense of humor, while a writer using British English would write sense of humour. Both forms refer to the same idea: the quality of being funny, the ability to enjoy funny things, or, as a verb, to indulge someone.
Quick Answer
For American English, use humor. For British English and many Commonwealth varieties, use humour. The two spellings have the same meaning and can work as both a noun and a verb. The safest rule is simple: choose the spelling that matches your audience and keep it consistent.
Why People Confuse Them
People confuse humour and humor because both spellings look correct in different places. You may see humor in US books, websites, school assignments, and workplace writing. Then you may see humour in British, Canadian, Australian, or Indian English.
The extra u is the main visual difference. Because both spellings appear in edited English, neither one looks completely wrong to many readers. The confusion gets stronger online, where American and British writing appear side by side.
Another reason is that the pronunciation is basically the same in everyday speech. You cannot hear the spelling difference when someone says the word. The choice only matters when you write it.

Meaning and Usage Difference
There is no meaning difference between humour and humor. They are regional spelling variants of the same word.
As a noun, the word can mean the quality that makes something funny.
Example:
The movie’s humor worked because the characters felt real.
It can also mean a person’s ability to enjoy or understand funny things.
Example:
She has a dry sense of humor.
As a verb, humor means to go along with someone’s request or idea, often to keep them happy.
Example:
Just humor me and read the first page.
For British-style writing, the same examples would use humour.
Compact comparison:
- Humour: same meaning, British/Commonwealth spelling.
- Humor: same meaning, American spelling.
- Main difference: spelling and audience, not definition.
- Pronunciation: usually the same in practical use.
Tone, Context, and Formality
Neither spelling is more formal, smarter, or more correct by itself. The right choice depends on the writing context.
In American writing, humour can look foreign, old-fashioned, or inconsistent unless the topic is British English, a title, a quotation, or a brand name. In British writing, humor can look noticeably American.
For a US audience, humor feels natural in almost every context: essays, emails, captions, articles, scripts, and workplace messages. It also fits medical and technical phrases in American English, such as vitreous humor.
Use humour when your whole document follows British or Commonwealth English. The important point is consistency. Do not write humor in one paragraph and humour in the next unless you are comparing the spellings.
Which One Should You Use?
Use humor if your readers are mainly in the United States. This is the best choice for US schools, US companies, American websites, and general American writing.
Use humour if your readers expect British or Commonwealth English. This may include writing for the UK, Australia, New Zealand, India, or many Canadian contexts.
Keep the original spelling in titles, names, direct quotes, and quoted phrases. For example, if a British book title contains humour, do not change it to humor. If an American article title contains humor, do not add a u.
A simple rule works well: match your audience, then stay consistent.
When One Choice Sounds Wrong
Humour sounds wrong in standard US writing when nothing else in the document uses British spelling.
Awkward for US writing:
The comedian’s humour made the audience laugh.
Better for US writing:
The comedian’s humor made the audience laugh.
Humor can look wrong in British-style writing because it breaks the expected spelling pattern.
Awkward for British-style writing:
The programme had a sharp sense of humor.
Better for British-style writing:
The programme had a sharp sense of humour.
One spelling may also look wrong if it appears next to other regional spellings from the opposite system. Mixing them makes the writing feel unedited.
Common Mistakes (and Quick Fixes)
A common mistake is saying humour is incorrect. It is not incorrect. It is just not the usual American spelling.
Another mistake is saying humor and humour are different kinds of comedy. They are not. “British humour” may describe a cultural style of comedy, but the spelling humour itself does not create a new meaning.
Writers also mix forms in one piece. That is usually a consistency problem.
Incorrect mix:
His humor was subtle, but her humour was louder.
Better US version:
His humor was subtle, but her humor was louder.
Also, do not write humourous as the adjective. The standard adjective is humorous, even in English varieties that use humour as the noun.
