Favor vs. Favour: What's the Difference?
favor for the US and favour for the UK.
Grammar Rule in 30 Seconds
Favor and Favour mean the exact same thing; the only difference is whether you are writing for an American or British audience.
- Use 'favor' (no U) for American English audiences, like in New York or Los Angeles.
- Use 'favour' (with a U) for British, Canadian, or Australian English audiences.
- Keep your spelling consistent throughout your entire document to maintain professional standards.
Overview
The distinction between favor (American English) and favour (British English) is one of the most recognizable markers of dialect in the English-speaking world. For a B1 learner, mastering this difference isn't just about spelling; it's about demonstrating linguistic awareness and adapting your writing for a specific audience. While the two words are identical in meaning and pronunciation, choosing the correct spelling signals a level of sophistication and attention to detail that is crucial in both academic and professional settings.
At its heart, this variation is not a grammatical error but a convention of orthography—the system of correct spelling. Both favor and favour can function as a noun (an act of kindness) or a verb (to show preference). The choice between them is determined entirely by the dialect you are writing in.
American English (US) prefers the -or ending, while British English (UK) and many Commonwealth nations (such as Australia, Canada, and New Zealand) use the -our ending. Understanding this pattern allows you to write with consistency and precision, whether you're submitting a paper to a US university or corresponding with a client in London.
This rule is part of a larger, systematic pattern of spelling differences that emerged from historical efforts to standardize the English language. American lexicographer Noah Webster famously simplified many spellings in the late 18th century to create a distinct American identity and make spelling more phonetic. The -our to -or change was a key part of this reform.
Therefore, learning this one rule for favor/favour unlocks the spelling for dozens of other words, such as color/colour, honor/honour, and labor/labour. Recognizing the system behind the spelling makes memorization far more efficient.
How This Grammar Works
favor and favour is completely consistent across both spellings. The word's function in a sentence, its part of speech, and its relationship to other words do not change. You only need to learn one set of grammatical rules and apply the spelling that matches your chosen dialect.favor/favour has two primary meanings. The most common is a kind or helpful act that someone does for you. In this sense, it is a countable noun. You can have one favor, or many favors.- US: Could you do me a
favorand pick up my mail? - UK: Could you do me a
favourand pick up my mail?
in favor of or to find favor with.- US: The committee voted in
favorof the new proposal. - UK: The committee voted in
favourof the new proposal. - US: His innovative ideas quickly found
favorwith the board of directors. - UK: His innovative ideas quickly found
favourwith the board of directors.
party favors (US) or party favours (UK), which are small gifts given to guests at a party.to favor/to favour means to support, to prefer, or to treat one person or group better than another. It is a transitive verb, which means it typically requires a direct object to receive the action.- US: The new regulations seem to
favorlarge corporations. - UK: The new regulations seem to
favourlarge corporations.
- US: The coastal climate
favorsthe cultivation of citrus fruits. - UK: The coastal climate
favoursthe cultivation of citrus fruits.
-s is added for the third-person singular present tense (he/she/it favors/favours), -ed is added for the past tense (favored/favoured), and -ing is added for the present participle (favoring/favouring).favor | favour | favored | favoured | favoring | favouring |favors | favours | favored | favoured | favoring | favouring |favorite/favourite (most preferred) and the adverb favorably/favourably (in a positive way) also follow the dialectal spelling rule. Your only task is to remain consistent within a single piece of writing.Formation Pattern
-or vs. -our spelling pattern is a direct result of two different historical paths. British English spelling retains the influence of Norman French, which became the language of the English court and administration after the Norman Conquest in 1066. Many French words for concepts like honor and color ended in -eur (e.g., couleur, honneur), which evolved into the -our ending in Middle English. This spelling became solidified in the influential dictionaries compiled in London, such as Samuel Johnson's A Dictionary of the English Language (1755).
-our endings to -or, believing the u was a silent, unnecessary relic. His dictionaries were widely adopted in the American education system, cementing these changes as standard American spelling.
-our in a British text, you can be almost certain its American equivalent ends in -or. The core rule is: British English often uses -our, while American English uses -or.
u is sometimes dropped in British English for certain derivatives when a suffix is added. For example, glamour becomes glamorous (the u is dropped), and honour becomes honorary. This is a more advanced point, but for a B1 learner, focusing on the primary words is key.
armor | armour | Noun. The place where it's stored is an armory/armoury. |
behavior | behaviour | Derivative: behavioral/behavioural. |
color | colour | Derivatives: coloring/colouring, colorful/colourful. |
demeanor | demeanour | No common derivatives. |
endeavor | endeavour | Functions as both a noun and a verb. |
favor | favour | Derivatives: favorite/favourite, favoritism/favouritism. |
flavor | flavour | Derivatives: flavoring/flavouring, flavorsome/flavoursome. |
glamor | glamour | Adjective is glamorous in both dialects (the u is dropped in UK). |
harbor | harbour | Functions as both a noun and a verb. |
honor | honour | Derivatives: honorable/honourable. The exception is honorary, which is common in both. |
humor | humour | The person is a humorist in both dialects. The adjective is humorous in both. |
labor | labour | Functions as both a noun and a verb. |
neighbor | neighbour | Derivative: neighborhood/neighbourhood. |
odor | odour | No common derivatives. |
rumor | rumour | Common phrase: rumor has it/rumour has it. |
savior | saviour | Often capitalized when referring to a religious figure. |
splendor | splendour | Adjective is splendorous in both dialects. |
vapor | vapour | Verb form: to vaporize/to vaporise. |
vigor | vigour | Adjective is vigorous in both dialects. |
When To Use It
favor and favour is audience and consistency. Your choice is not about being "correct" in an absolute sense, but about being appropriate for your reader and the context of your writing. Misusing the convention won't usually cause a breakdown in communication, but it can appear unprofessional or careless to a native reader.- 1Know Your Audience: This is the most important factor. If you are writing for a predominantly American audience, use
-orspellings. If you're writing for a British, Australian, Canadian, or New Zealander audience, use-ourspellings.
- Academic Writing: A paper for a professor at a US university requires
favor,color,labor. The same paper for a UK university requiresfavour,colour,labour. Many academic style guides (like APA or MLA) default to American spellings, while others (like MHRA) use British spellings. - Professional Communication: An email to a company based in New York should use
favor. A proposal sent to a firm in London or Sydney should usefavour. Aligning your spelling with your client's or colleague's dialect is a sign of respect and global awareness. - International Contexts: If your audience is mixed or global (e.g., a public website, an international organization), you must choose one convention and stick with it. American English is often the default in international business and science, but this is not a universal rule. Check for a house style guide if one exists.
- 1Maintain Consistency: Once you choose a convention, you must use it consistently throughout your entire document. Mixing
favorandcolourin the same essay is a clear sign of error. This is a common mistake that spell-checkers can sometimes miss if they are set to the wrong dialect or are not used carefully.
- Incorrect: I asked my
neighbourfor afavor. - Correct (US): I asked my
neighborfor afavor. - Correct (UK): I asked my
neighbourfor afavour.
- 1Set Your Tools: Modern word processors and text editors have a language setting. Before you begin writing, set the proofing language to "English (US)" or "English (UK)". This will automatically flag inconsistencies for you and is the single most effective way to maintain consistency. Forgetting this step is the source of most dialect-mixing errors.
-our spelling for nouns like favour and colour, but may use the American -ize verb ending instead of -ise (realize instead of realise). However, for the -or/-our pattern, it almost always aligns with British usage.Common Mistakes
favour but then later use the American spelling honor in the same text. This mixing of dialects looks unprofessional.- Error: The
labourreport was received with greatfavorby the board. - Why it's wrong: It mixes a British spelling (
labour) with an American spelling (favor). - Correction (UK): The
labourreport was received with greatfavourby the board. - Correction (US): The
laborreport was received with greatfavorby the board.
-or/-our pattern but then over-apply it to words that do not follow this rule. Many words of Latin origin end in -or in both dialects. Applying the -our spelling to them is a common form of hypercorrection.- Error: My
doctouradvised me to rest. Theactourgave a great performance. - Why it's wrong:
Doctor,actor,governor,error,terror, andmirroralways end in-orin both US and UK English. They were not part of the set of words that had the French-ourending in Middle English. - Rule of thumb: The
-ourspelling is primarily for a specific list of abstract nouns and their related verbs. It doesn't apply to words describing professions or roles ending in-or.
favour correctly but then stumble on the adjective or adverb form.- Error: It is my
favouritebook, and the critics reviewed itfavorably. - Why it's wrong: This example again mixes dialects. The adjective
favouriteis British, while the adverbfavorablyis American. - Correction (UK): It is my
favouritebook, and the critics reviewed itfavourably. - Correction (US): It is my
favoritebook, and the critics reviewed itfavorably.
glamor and vigor. While the UK noun is glamour, the adjective is glamorous (without a u) in both dialects. A learner might incorrectly write glamourous.- Error (UK perspective): She lived a very
glamourouslife. - Correction (UK & US): She lived a very
glamorouslife.
-our spelling can mislead learners into thinking the pronunciation is different. It is not. Both favor and favour are pronounced identically: /ˈfeɪ.vər/. The u is purely an orthographic convention and has no impact on the sound of the word.Real Conversations
In everyday, informal communication, the rules still apply, but the context dictates how strictly they are followed. Native speakers are generally consistent even in casual writing, as it's an ingrained habit. Here’s how you might see favor/favour used in modern, real-world contexts.
Texting & Social Media:
In texts and on platforms like Twitter or Instagram, language is often abbreviated. However, the core spelling choice usually remains.
- US User (Text): hey can u do me a huge favor and grab my jacket?
- UK User (Text): Can you do me a quick favour pls? Need you to vote for my photo!
- US User (Instagram Caption): Enjoying the sunny weather. California definitely gets my vote for favorite state. ☀️
- UK User (Twitter Post): Just tried the new cafe on high street. Their flat white is my new favourite. Highly recommend.
Work Emails:
In a professional context, correctness and adherence to the local dialect are expected. This is where getting it right matters most.
- Email to a US Colleague:
Subject
Hi John,*
Just wanted to follow up on the Q3 labor report. The initial data seems to favor the new marketing strategy. Let me know if you need any help with the analysis.*
Best,*
Sarah*
- Email to a UK Client:
Subject
Dear Mr. Davies,*
Thank you for your time today. We were delighted that our proposal found favour with your team. We believe our firm is in an honourable position to deliver on this project and look forward to your decision.*
Kind regards,*
Ben*
Casual Spoken Conversation:
Remember, in speech, there is no difference. The following sentences would sound exactly the same whether spoken by an American or a Brit.
- "Could you do me a favor?"
- *"I'm not a fan of that color."
- *"It's an honor to be here."
This is why the distinction is purely a writing concern. You don't need to worry about it when you're speaking, but you must be mindful of it as soon as you start to type.

Memorize It
Mnemonic
American English is 'short' on letters, so they drop the 'U'. British English is 'full' of tradition, so they keep the 'U'.
Visual Association
Imagine a British person holding a 'U'-shaped umbrella in the rain. They need that 'U' to stay dry! An American is in the sun and doesn't need the umbrella, so they drop the 'U'.
Rhyme
In the USA, the 'U' goes away; in the UK, the 'U' will stay.
Story
Noah Webster was an American who wanted to make spelling easier. He looked at the word 'favour' and thought, 'That U is doing nothing!' He took his scissors and snipped it out. Meanwhile, in London, Samuel Johnson was writing his dictionary and decided the 'U' looked elegant and royal, so he kept it in.
Word Web
Challenge
Write three sentences about a time you helped a friend. If you are in the US, use 'favor'. If you are elsewhere, use 'favour'. Check that you didn't mix them!
Cultural Notes
In the US, 'favor' is used for everything from kind acts to physical resemblance. It is part of the simplified spelling movement led by Noah Webster.
In the UK, 'favour' is the only acceptable spelling. Using 'favor' might be seen as an 'Americanism' and is often discouraged in schools.
Canada usually follows British spelling for words like 'favour' and 'colour', but because of their proximity to the US, you will often see 'favor' in informal contexts.
Derived from the Old French 'faveur', which comes from the Latin 'favorem' (goodwill, kindness).

Neither is 'more' correct. It depends entirely on where you are. In the US, `favor` is the only correct spelling. In the UK, `favour` is the only correct spelling.
It is better to use `favour` in Canada, as they generally follow British spelling rules, though American influence is strong.
No, the pronunciation is identical: /ˈfeɪ.vər/. The 'u' is silent.
They follow the exact same rule! `Favorite` is American, and `favourite` is British.
It can be both. 'Do me a favor' is neutral/informal, while 'The court ruled in favor of...' is very formal.
Noah Webster wanted to simplify English and remove 'unnecessary' letters that weren't pronounced.
No! This is considered a major error in professional and academic writing. Pick one and stay consistent.
Yes, Australia uses British spelling, so `favour` is the standard there.
