Quick Answer
The fastest way to know which spelling to use.
The difference between flavor and flavour comes down entirely to geography.
If you are writing for an audience in the United States, the correct spelling is flavor. If you are writing for an audience in the United Kingdom, Australia, or Canada, the correct spelling is flavour.
Both words mean exactly the same thing: the distinctive taste of a food or drink, or a specific quality of something. Neither spelling is grammatically incorrect, but using the wrong one for your target region can look out of place.

American English: Flavor
How the word is used in the United States.
In the United States, "flavor" is the universally accepted spelling. It is used by the Food and Drug Administration (FDA), major food corporations, culinary schools, and everyday speakers. The spelling drops the letter "u" entirely, favoring a streamlined approach that aligns with its Latin roots.
Industry Standard
American food regulators and manufacturers exclusively use "flavor" on packaging, ingredient lists, and nutritional labels.
Media and Publishing
Major publications like The New York Times and The Wall Street Journal follow the "flavor" spelling.
British English: Flavour
How the word is used in the United Kingdom.
In the United Kingdom, "flavour" is the traditional and standard spelling. It retains the "u" from its Old French roots, matching other British spellings like "colour" and "honour." It remains the undisputed standard in British English, from supermarket packaging to fine dining menus.
Cultural Presence
The spelling is common in everyday British culture, seen in phrases like 'flavour of the month' or 'extra flavour crisps'.
Modern Usage
Though informal texts might use abbreviations, formal British writing relies on 'flavour' rather than the American adaptation.
What Do Both Words Mean?
The definition remains exactly the same.
Despite the spelling difference, both "flavor" and "flavour" mean exactly the same thing. They function as both a noun (the distinctive taste of a food or drink, or a specific quality) and a verb (to add flavor to something).
Core Definition
The sensation of taste and smell when eating or drinking, or a specific variant of something.
Verb Form
To season food or to give a distinct quality or character to something.
American English Usage
How Americans naturally use the word today.
In the US, "flavor" is used in almost every context, from casual conversation to food science. It applies to both the noun and verb forms interchangeably.
Casual Conversation
"What's your favorite ice cream flavor?"
Technical Writing
"The chemist added an artificial flavor to the mixture."
Social Contexts
"The party had a distinct 1980s flavor."
Food Industry
"The company introduced three new flavors this quarter."
British English Usage
How Britons naturally use the word today.
In the UK, "flavour" holds its ground in recipes, food packaging, and everyday life. Whether discussing crisps or a gourmet meal, the 'u' is retained.
Literature and Media
"The article described the unique flavour of the local cuisine."
Everyday Conversation
"These crisps come in a brilliant new flavour."
Hobbyist Contexts
"She prefers the traditional flavour of English mustard."
News and Journalism
"The new restaurant offers a modern flavour of Mediterranean dining."
Which Spelling Should You Use?
Deciding based on your audience.
The decision is entirely context-driven. If you are writing a recipe for an American food blog, use "flavor." If you are writing a cookbook for a British publisher, use "flavour."
Choose "Flavor" if:
You are writing for a US-based publisher, studying at an American school, or creating content primarily for an American audience.
Choose "Flavour" if:
You are submitting to a UK journal, writing for a British audience, or following Commonwealth English standards.
Formal and Professional Writing
What to do in business and academic contexts.
In highly formal writing, it is crucial to match the regional standard of your target publication. Unlike some words that have a universally accepted alternative, there is no 'neutral' spelling for this word—you must choose between the US and UK versions.
Business Contracts
International food standards often require region-specific labeling, meaning US products use 'flavor' and UK products use 'flavour'.
Academic Research
Food science papers should align with the spelling standard of the journal, whether American or British.
Pronunciation
The spelling change does not affect how the word is spoken.
Despite the spelling difference, the pronunciation remains exactly the same in both American and British English. The 'u' in the British spelling is silent.
| Word | IPA | Syllables |
|---|---|---|
| Airplane (US) | /ˈfleɪvər/ | 2 (FLAY-ver) |
| Aeroplane (UK) | /ˈfleɪvər/ | 2 (FLAY-ver) |
Because the 'o' and 'u' combine to form a single schwa sound (or a similar 'er' sound in rhotic American English), both words share the exact same two-syllable pronunciation.
Spelling Difference
A visual breakdown of the letters.
The core difference is the presence of the letter "u" after the "o."
The American version simply drops the "u" entirely. The British version retains the "u," which is a remnant of the word's Old French origins, keeping it consistent with words like 'colour' and 'honour'.
Why Are the Spellings Different?
The history behind the transatlantic split.
1. The Old French Roots
The word entered Middle English from Old French as 'flaur' (later 'flavour'). The 'u' was a standard part of the spelling, adapted from the Old French suffix patterns.
2. Noah Webster's Reform
In the early 1800s, American lexicographer Noah Webster wanted to create a distinctly American version of English. He believed spellings should be simpler, more phonetic, and free of unnecessary silent letters. He dropped the 'u' in words like 'flavour', 'colour', and 'honour', reverting them closer to their Latin roots.
3. The American Standard
By dropping the 'u', Americans turned a French-influenced spelling into a clean, streamlined word. While Britain kept the 'u', the American 'flavor' became the undisputed standard in the United States.
