Both rumour and rumor are correct spellings, but the right choice depends on the type of English you are using.
Rumour is the standard spelling in British English, while rumor is the standard spelling in American English. Both words have the same meaning and refer to a story or piece of information that people share without knowing for sure if it is true.
The confusion around rumour or rumor often comes from the different spelling rules used in the United Kingdom and the United States. British English often keeps the letter u in words such as colour, favour, and honour. American English usually drops that u, producing color, favor, and honor.
You may also see searches such as rumor or rumour, rumour vs. rumor, rumor vs. rumour, rumour and rumor, and rumor and rumour. These variations all point to the same question: which spelling should you use?
This guide explains the difference, the meaning and origin of the word, regional preferences, common mistakes, and practical examples to help you choose the right spelling for your audience.

What Does Rumour and Rumor Mean?
Definition of Rumour
A rumour is a story, claim, or piece of information that people share without knowing if it is true. It may spread through conversations, messages, social media, or news discussions.
For example, someone might say that a company plans to open a new office. If people repeat the claim but the company has not confirmed it, it may be described as a rumour.
The spelling rumour is standard in British English and other varieties that follow British spelling conventions.
Definition of Rumor
A rumor has exactly the same meaning as rumour. It describes information that circulates among people without reliable confirmation.
For example, an American employee might say, “I heard a rumor that our office is moving.”
The spelling rumor is standard in American English. It is common in American newspapers, books, workplace messages, and online publications.
Is Rumour or Rumor a Noun or a Verb?
Both spellings can function as nouns and verbs, although the noun is especially common in everyday use.
As a noun:
- A rumour spread across the school.
- A rumor about the actor appeared online.
As a verb:
- People began to rumour that the shop would close. This use is possible in British English, though it is less common.
- American English can use rumor as a verb, as in “They rumored that the company would close.”
The verb often sounds less natural in ordinary conversation than phrases such as spread a rumour, start a rumor, or repeat a rumor.
What Is the Difference Between Rumour and Rumor?
There is no difference in meaning. The only standard difference is the spelling convention.

The Origin of Rumour and Rumor
Where Does the Word Rumour Come From?
The English word rumour came through Old French rumour, meaning noise, report, or public talk. Its history can be traced further back to Latin rumor, which referred to talk, hearsay, or a report circulating among people.
Over time, the word became associated with information passed from person to person, especially information that had not been confirmed.
Today, rumour is used in everyday conversations, journalism, politics, entertainment, and business. It can describe anything from a harmless story about a surprise party to a serious claim that needs careful verification.
Why Does American English Use Rumor?
American English developed its own spelling conventions over time. In many words derived from French, British English retained the letter u, while American English adopted shorter forms.
Examples include:
- Colour and color
- Favour and favor
- Honour and honor
- Labour and labor
- Rumour and rumor
These differences are part of the broader history of English spelling. They do not indicate that one version is more correct than the other.
The spelling rumor became established in American English, while rumour remained standard in British English.
Is Rumor an American Misspelling of Rumour?
No. Rumor is not a misspelling when used in American English. It is the accepted American form.
Likewise, rumour is not incorrect in British English. The important point is to use the spelling that matches your intended audience and maintain consistency throughout your writing.
For example, an American article would normally use rumor, color, and favor. A British article would normally use rumour, colour, and favour.
British English vs. American English
Which Spelling Is Used in Each Country?
The main distinction between rumour vs. rumor follows familiar British and American spelling patterns.
| British English | American English | Example |
| Rumour | Rumor | The rumour spread quickly. |
| Rumours | Rumors | Several rumours circulated online. |
| Rumoured | Rumored | The rumoured event was cancelled. |
| Rumouring | Rumoring | They were rumouring about a possible change. |
| Colour | Color | The colour was bright. |
| Favour | Favor | She asked for a favour. |
| Honour | Honor | It was an honour to attend. |
The examples in the final three rows demonstrate the same spelling pattern in related words. They are not different in meaning simply because the spellings vary.
What About Canadian and Australian English?
Canadian English generally follows rumour, while Australian English also uses rumour. These varieties retain the u in many words that American English spells without it.
However, regional writing practices can vary by publication, organization, or style guide. If you are preparing material for a particular institution, follow its stated spelling preferences.
Do the Two Spellings Sound Different?
In most standard varieties, rumour and rumor are pronounced the same or very similarly. The difference is mainly written, not spoken.
The word is commonly pronounced with two syllables, with the stress on the first syllable. Exact vowel sounds can vary by accent.
This means you usually cannot identify the spelling by listening to someone say the word. You must use the appropriate regional spelling when writing it.
Which Version Should You Use?
In the United States
Use rumor in school assignments, business emails, blog posts, reports, and American publications.
Example: “A rumor about the new policy circulated among employees.”
In the United Kingdom
Use rumour in British English writing.
Example: “A rumour about the new policy circulated among employees.”
In Canada
Use rumour in general Canadian English writing, unless your publication or organization specifies a different house style.
Example: “The rumour appeared on several local websites.”
In Australia
Use rumour for standard Australian English.
Example: “A rumour spread throughout the community.”
In International Writing
Choose the spelling that best matches your intended audience. If your article is aimed mainly at American readers, use rumor. If it is aimed at British, Australian, or Canadian readers, rumour is generally the more suitable choice.
For a broad international audience, either form can work, provided you apply it consistently.
In Academic Writing
Follow the spelling conventions required by your university, instructor, journal, or academic publisher.
If the assignment uses American English, write rumor. If it uses British English, write rumour. Avoid switching between the two forms in the same paper unless you are quoting a source that uses a different spelling.
In Business Writing
Use the spelling preferred by your organization and target market.
For example, a company writing for US customers might use rumor, while a company writing for UK customers might use rumour. In sensitive workplace situations, consider using more precise terms such as unverified report or unconfirmed claim.
Common Mistakes When Using Rumour or Rumor
Mistake 1: Treating One Spelling as Always Wrong
Incorrect claim: “Rumour is always wrong in American English.”
Correct explanation: Rumor is the standard American spelling, while rumour is the standard British spelling.
Memory tip: Think of rumour as the British form and rumor as the American form.
Mistake 2: Mixing Spellings in One Article
Incorrect: “A rumor spread through London, and several colours appeared in the report.”
Correct in British English: “A rumour spread through London, and several colours appeared in the report.”
Correct in American English: “A rumor spread through London, and several colors appeared in the report.”
Explanation: Use one regional spelling system throughout your writing unless you are quoting another source.
Mistake 3: Confusing Rumour With Confirmed News
Incorrect: “The rumor proves that the company is closing.”
Correct: “The rumor suggests that the company may be closing, but the claim remains unconfirmed.”
Explanation: A rumour or rumor does not automatically establish that information is true. The word often signals uncertainty.
Mistake 4: Using the Wrong Plural
Incorrect: “Several rumour spread online.”
Correct in British English: “Several rumours spread online.”
Correct in American English: “Several rumors spread online.”
Explanation: The noun takes a regular plural ending. The British spelling retains the u, while the American spelling does not.

British English uses rumoured and rumouring. American English generally uses rumored and rumoring.
For example:
- British: “The singer was rumoured to be retiring.”
- American: “The singer was rumored to be retiring.”
Memory tip: Once you choose rumour or rumor, keep the same spelling pattern in related forms.

Google Trends and Modern Usage
Why Do People Search for Rumour or Rumor?
People commonly search for rumour or rumor because the two spellings look almost identical, and the difference is easy to overlook. Writers may also be unsure if one form is a spelling mistake or simply a regional variation.
Search phrases such as rumor or rumour, rumour vs. rumor, rumor vs. rumour, rumour and rumor, and rumor and rumour reflect this spelling question.
The word itself remains useful in conversations about social media, public statements, celebrity news, workplace communication, and unverified claims.
Which Spelling Is More Popular?
The preferred spelling depends mainly on the region and the writing conventions used there. Rumor is standard in the United States, while rumour is common in the United Kingdom, Canada, and Australia.
Without a defined time period and verified search data, it would be misleading to give exact search volumes or claim that one form is more popular worldwide.
Google Trends can help compare relative search interest across locations and periods. However, search activity alone does not determine which spelling is correct for a particular audience.
How Has Online Writing Affected Usage?
Online content brings different English varieties together. A British reader may encounter rumor in an American news article, while an American reader may see rumour on a British website.
Both forms can appear in international discussions, but professional writers should maintain a consistent spelling style. Readers are more likely to understand the intended meaning when the surrounding article follows a clear and familiar convention.
Does Rumour Mean the Same Thing as Gossip?
The words overlap, but they are not always interchangeable.
A rumour is an unconfirmed story or claim that spreads among people. Gossip often involves casual talk about other people’s private lives or personal affairs.
For example, a claim that a company will close is often called a rumour. Casual talk about a colleague’s personal life may be described as gossip.
Understanding this distinction helps writers choose the most accurate word for their subject.
