“Favor” and “favour” are both correct spellings of the same English word. “Favor” is the standard form in American English, while “favour” is standard in British English and commonly used in Canadian, Australian, and New Zealand English. Choose the spelling required by your audience, publisher, employer, or house style, then apply that regional pattern consistently.
Key facts at a glance
Favor is the usual American English spelling.
Favour is the usual British, Canadian, Australian, and New Zealand spelling.
The two forms have the same meaning and normally the same pronunciation.
Related forms change too: favored/favoured, favorite/favourite, and favorable/favourable.
A publisher’s style guide outranks a general country preference.
Mixed spelling is usually an editing problem, except in quotations, proper names, or technical identifiers.
Favour or Favor: Which Spelling Should You Use?
Use favor for a US audience and favour for a British or Commonwealth audience. For an international document, follow the organization’s established style rather than assuming that the shorter American form is universally preferable.
| Writing situation | Recommended form | Reason |
|---|---|---|
| US school assignment | favor | American spelling convention |
| UK government report | favour | British institutional style |
| Canadian consumer page | favour | Common Canadian usage |
| Australian newspaper copy | favour | Australian English convention |
| US software interface | favor | US localization and code conventions |
| Global company policy | House style | Corporate consistency overrides geography |
The choice is not a judgment about correctness, education, or formality. A British editor should not change favour to favor merely to shorten a document, and an American editor should not add the u to imitate a supposedly more formal register.
The strongest practical rule is simple: identify the reader first, check the controlling style guide second, and search the finished document for regional variants third.
Do the Two Spellings Have Different Meanings?
No. Favor and favour normally have identical meanings, grammatical roles, pronunciations, and inflections. The difference is orthographic, meaning that it concerns written form rather than the underlying word.
As a noun, the word can mean an act of help or kindness: “Could you do me a favor?” It can also mean support or approval: “The proposal passed in favor of the amendment.”
As a verb, the word means to prefer, support, or treat advantageously: “The selection process favors applicants with relevant experience.” The British version uses the same meanings: “Could you do me a favour?” and “The policy favours smaller suppliers.”
Merriam-Webster defines the American noun favor as “a kind or helpful act that you do for someone.” Cambridge Dictionary lists favour as the British spelling and gives the same core meanings, confirming that the regional distinction does not create a semantic distinction.
Does pronunciation change?
Usually, no. English speakers generally pronounce both forms as /ˈfeɪ.vər/, approximately “FAY-vər.” Accent affects the final vowel more than the spelling does.
Pronunciation can vary across regions, especially in unstressed syllables, but favor is not pronounced differently from favour merely because one version contains u. The extra letter is a regional spelling convention.
Which Spelling Belongs in American English?
Favor is the standard American English form, including in formal writing, journalism, academic prose, business communication, and government documents. American English also removes the u in related forms such as favored, favorite, and favorable.
| Meaning or grammatical role | American English | Example |
|---|---|---|
| Noun or verb | favor | “The voters favor the proposal.” |
| Past tense | favored | “The committee favored option B.” |
| Present participle | favoring | “The evidence is favoring reform.” |
| Adjective | favorite | “That is my favorite example.” |
| Adverb | favorably | “The plan was viewed favorably.” |
| Abstract noun | favoritism | “The policy aims to prevent favoritism.” |
The American pattern also appears in compounds and fixed expressions, including in favor of, favorability, and favorably disposed. Spellcheckers set to English (United States) generally recognize these forms automatically.
Noah Webster helped popularize systematic American preferences for spellings such as color, honor, and favor. His American Dictionary of the English Language, published in 1828, recorded and promoted an emerging American spelling system, but the change was gradual and had multiple historical causes. Webster did not single-handedly create every American spelling.
Which Spelling Belongs in British and Commonwealth English?
Favour is the standard British English spelling and is also widely used in Canada, Australia, and New Zealand. Ireland commonly uses British-style spellings in formal publishing, although individual organizations may specify their own editorial rules.
| English variety or context | Usual form | Typical related forms |
|---|---|---|
| British English | favour | favoured, favourite, favourable |
| Canadian English | favour | favoured, favourite, favourable |
| Australian English | favour | favoured, favourite, favourable |
| New Zealand English | favour | favoured, favourite, favourable |
| Irish institutional English | favour | favoured, favourite, favourable |
| South African English | favour | publisher-dependent, often British-style |
Commonwealth usage is not perfectly uniform. Canadian English, for example, combines British and American features in different vocabulary groups, so the Canadian Oxford Dictionary, a government guide, or a publication’s own manual should settle disputed cases.
The u is not an indication that the word is older, more literary, or more formal. It identifies a spelling tradition. A British legal contract using favour is not inherently more elevated than a US contract using favor.
Why Does One Form Have a U?
The modern difference developed through the interaction of French influence, English spelling history, printing practice, and American standardization. English inherited the word through Anglo-French and Middle English forms related to Latin favor, meaning goodwill, approval, or partiality.
Many British spellings retained -our in words associated with French forms, including colour, honour, labour, and favour. American spelling gradually preferred -or in several of these words.
Webster’s dictionaries gave American readers a consistent reference point and helped establish national conventions during the nineteenth century. The explanation is therefore more accurate as a history of standardization than as a claim that one person simply removed letters from the language.
The two spellings remain connected to the same etymological family. The regional difference is visible, but the word’s origin does not make either modern form more correct.
How Should You Spell the Related Words?
Change the related forms as a group. Writers who choose favor normally use favored, favorite, and favorable; writers who choose favour normally use favoured, favourite, and favourable.
| Function | American form | British/Commonwealth form |
|---|---|---|
| Past tense | favored | favoured |
| Present participle | favoring | favouring |
| Adjective | favorite | favourite |
| Adverb | favorably | favourably |
| Abstract noun | favoritism | favouritism |
| Noun expressing approval | favorability | favourability |
One important spelling detail is easy to miss: the present participle is favoring/favouring, not favouring in the American form. The final e is dropped before -ing, while the regional u remains or disappears according to the base spelling.
A sentence such as “The manager favored his favorite supplier because the terms were favorable” follows American style. The British equivalent is “The manager favoured his favourite supplier because the terms were favourable.”
How Should You Choose a Regional Spelling?
Choose a regional spelling in four steps:
- Identify the primary audience. Use the readers’ expected variety of English, not the location of your keyboard.
- Check the governing style guide. A journal, employer, government department, or client may impose a specific standard.
- Set the document language. Select English (United States), English (United Kingdom), English (Canada), or the required local setting in Microsoft Word, Google Docs, or another editor.
- Run a consistency search. Search for favor, favour, favorite, favourite, favored, favoured, favorable, and favourable.
The style guide has priority when audience and institution point in different directions. A Canadian author submitting to a US journal may need favor, while a US author writing copy for a UK campaign may need favour.
For a mixed international audience, do not alternate forms by paragraph. Pick the form used by the publication’s principal audience, or publish separate localized versions when search behavior, legal requirements, or brand voice justify it.
Is consistency always mandatory?
Consistency is the default, not an absolute rule. A document can contain both forms legitimately when it preserves a direct quotation, reproduces a company or product name, cites a source title, or displays a technical identifier.
The editing error is accidental switching within the author’s own prose. A British article may quote an American speaker saying “do me a favor,” then continue with “the policy will favour residents.” The quotation retains its original spelling; the surrounding prose follows the article’s style.
Should Websites Use Favor or Favour for SEO?
Websites should use the spelling used by the target search market, while making the page’s meaning clear enough for users and search systems to connect both variants. Search engines generally understand favor and favour as regional spellings of the same lexical entity, but regional wording still affects user trust, local relevance, and query matching.
| Website target | Primary spelling | Supporting SEO action |
|---|---|---|
| United States | favor | Use US English in navigation and metadata |
| United Kingdom | favour | Use UK spelling throughout visible copy |
| Canada | favour | Confirm local style for product and legal terms |
| Australia | favour | Use Australian editorial settings |
| Global English site | Brand or audience standard | Add localized pages when demand justifies them |
| Search comparison page | Both forms | Explain the regional distinction explicitly |
Do not create thin duplicate pages solely for the two spellings. One authoritative page can explain both forms, use the appropriate primary variant, and include the alternate form where it helps the reader.
Localized sites require more than replacing one letter. Adapt color/colour, organize/organise, date formats, currency, legal terminology, and product vocabulary according to the market. A page that changes favor to favour but retains US-only wording may look mechanically localized.
What is the 83% versus 17% claim?
The often-repeated 83% versus 17% global split is not a dependable universal statistic. English-language corpus proportions vary according to the years sampled, country weighting, genre, domain distribution, and treatment of duplicated web content.
The same caution applies to claims that favor has a fixed global market share or that favour represents an exact percentage of Commonwealth text. Without a named corpus, methodology, sample size, and publication year, those figures should not be presented as measured facts.
For SEO decisions, first-party Search Console data, regional keyword tools, analytics, and conversion behavior are more useful than a global percentage. A Toronto retailer and a Texas software company should not make the same spelling decision because an undifferentiated worldwide estimate says so.
Can Programming Code Use Favour?
Programming code may use either spelling in user-facing text, but identifiers and API fields must match the software specification exactly. Developers should never rename a variable, database column, endpoint, CSS class, or JSON key merely to make prose follow British English.
| Code element | Example | Editing rule |
|---|---|---|
| User-facing label | Add to favourites |
Localize freely |
| JavaScript variable | favoriteItems |
Preserve the defined identifier |
| Database field | favorited_at |
Do not rename without migration |
| API parameter | is_favorited |
Follow the API contract |
| CSS class | .favorite-button |
Match stylesheet references |
| Product trademark | Favorites |
Preserve the owner’s spelling |
A UK interface can display “Add to favourites” while its backend uses favoriteItems. That is not inconsistent editing; it is a separation between localized presentation and technical compatibility.
The same principle applies to software documentation. Explain the interface in the reader’s regional English, but reproduce code exactly. Code formatting is governed by syntax and contracts, not by the prose style sheet.
What Are the Most Common Mistakes?
The most common error is accidental regional mixing in ordinary prose, especially when derivative forms are not checked. A document may use favour in its introduction but retain favorite in headings, image captions, or metadata.
| Mistake | Why it happens | Reliable correction |
|---|---|---|
| favour beside favorite | Manual editing or copied text | Convert the complete word family |
| Changing a quotation | Overzealous proofreading | Preserve the quoted source |
| Renaming an API field | Confusing prose with code | Follow the technical contract |
| Treating Canadian English as purely British | Overgeneralization | Check the publisher or Canadian guide |
| Using a global percentage | Unsourced SEO advice | Use regional data and named corpora |
| Switching styles by webpage | Multiple contributors | Set one project-level language standard |
A search-and-replace pass can repair simple documents, but broad replacements may damage names, URLs, code, and quotations. Review every replacement in context, especially when the search term occurs inside a longer technical string.
An editorial checklist catches the remaining problems:
- Search both root forms.
- Search all related derivatives.
- Inspect headings, buttons, captions, alt text, and metadata.
- Verify quotations and proper names.
- Check code blocks separately.
- Confirm the document language before final proofing.
When Should You Use the Other Form?
Use the other regional form when the text represents another speaker, publication, legal entity, or market. Regional spelling can carry voice information, but it should not be used to caricature a nationality or imply that one variety is more intelligent.
For fiction, match the narrator, publisher, and setting only when the choice supports the work’s editorial system. A novel written by an American author about London does not automatically require British spelling throughout; the publisher may retain a house style while using vocabulary and dialogue to establish setting.
For academic writing, follow the journal’s instructions rather than the author’s home variety. The Publication Manual of the American Psychological Association, for example, governs APA publications, while a British journal may specify its own preferred forms.
For legal writing, preserve exact wording in statutes, contracts, quoted evidence, and registered names. Local drafting conventions matter, but precision matters more than cosmetic uniformity.
For marketing, use the audience’s local spelling on landing pages, calls to action, product descriptions, and customer support content. A local variant can improve perceived fluency even when search engines recognize both spellings.
What If a Document Contains Both Spellings?
If a document contains both spellings accidentally, select the required style, convert the ordinary prose and derivatives, then inspect exceptions manually. The safest repair sequence takes approximately 10-20 minutes for a typical 2,000-word document, depending on the number of quotations and code samples.
Start by identifying the controlling style. Next, search the full word family rather than only the root, because favorite, favoured, and favourable will not all be fixed by replacing one root string.
Then classify each remaining exception:
- Keep direct quotations unchanged.
- Keep official names and titles unchanged.
- Keep API keys, variables, and database fields unchanged.
- Change ordinary authorial prose.
- Review metadata and interface labels separately.
A document can therefore contain both favor and favour after a correct edit. The objective is not mechanical uniformity across every character; the objective is intentional, explainable usage.
Is Favour More Formal Than Favor?
No. Favour is not inherently more formal, traditional, academic, or correct than favor. Both forms work in formal writing when they match the selected variety of English.
The apparent formality difference usually comes from exposure. A UK reader may find favour visually normal and favor foreign, while a US reader may have the opposite reaction. Reader familiarity affects tone perception, but it does not change the word’s register.
The same rule applies to colour/color, honour/honor, and labour/labor. Regional spelling is a variety marker, not a scale from informal to formal.
FAQ
Is “do me a favor” correct in the UK?
“Do me a favour” is the usual UK spelling, while “do me a favor” is the usual US spelling. Both expressions mean the same thing. A UK publication would normally change the American form in its own prose, but it should preserve favor inside an exact quotation or official title.
Is “favour” accepted in American English?
Readers will understand favour, but American publishers, schools, employers, and software typically expect favor. An American writer should use favour only when reproducing a source, preserving a name, addressing a Commonwealth audience, or following a specific editorial requirement.
Is “favorite” British or American?
Favorite is the American spelling. British, Canadian, Australian, and New Zealand English usually use favourite. The noun can describe a preferred person or thing, as in “my favorite book” or “my favourite book,” with no difference in meaning or pronunciation.
Is the correct spelling “favored” or “favoured”?
Favored is the American form, and favoured is the British and Commonwealth form. Both are the past tense and past participle of the verb. Use the form that matches the base style: American documents generally use favor, while British-style documents use favour.
Does Microsoft Word know which form to use?
Microsoft Word can identify the preferred form when the proofing language is set correctly. Choose English (United States), English (United Kingdom), English (Canada), or another relevant setting before editing, then review regional exceptions such as quotations, names, and code.
Should an international website use both forms?
An international website can explain both forms on one page, but ordinary copy should use one primary regional style. Use separate localized pages when the markets require different spelling, currency, legal notices, customer-support language, or search strategies. Do not alternate favor and favour randomly for perceived SEO benefit.
The Bottom Line
Favour or favor, which is correct? Both are correct spellings of the same English word. Choose favor for American English and favour for British, Canadian, Australian, New Zealand, and many Irish or South African contexts, unless a publisher, employer, client, quotation, brand name, or technical specification requires another form. Consistent, intentional regional usage is the correct professional standard.
