If you’ve seen both analyzed and analysed, you may wonder which spelling is actually correct. The answer is simple: both spellings are correct, but they belong to different varieties of English.
Analyzed is the standard spelling in American English, while analysed is the preferred spelling in British English and many countries influenced by British writing conventions. This guide explains the differences, where each spelling is used, and which version you should choose for your audience.
Why Analyzed And Analysed Are Both Correct Spellings
Quick Answer: Analyzed and analysed mean exactly the same thing. The only difference is regional spelling. Americans use analyzed, while British writers typically use analysed. Neither spelling is wrong when used in the correct regional context.
The confusion comes from the broader spelling differences between American and British English. Similar patterns appear in words such as color and colour, honor and honour, and vapor and vapour.
In both cases, the word means:
To examine something carefully in order to understand it, interpret it, or evaluate it.
Examples:
- US English: The researchers analyzed the survey results.
- UK English: The researchers analysed the survey results.
The meaning remains identical.
Analyzed Vs Analysed Across Major English-Speaking Countries
English spelling varies from one country to another. Understanding regional preferences helps you write more naturally for your intended audience.
| Country | Preferred Spelling |
| United States | Analyzed |
| United Kingdom | Analysed |
| Canada | Usually Analyzed, Both Accepted |
| Australia | Analysed |
| New Zealand | Analysed |
| India | Often Analysed, Both Accepted |
Canada
Canadian usage can be mixed. Many publications prefer American-style spellings, while others retain British conventions. As a result, both forms may appear.
India
Indian English often follows British spelling traditions, making analysed common in academic and professional writing.
Is It Analyze Or Analyse? Understanding The Verb Behind Both Spellings
The spelling difference begins with the base verb.
| American English | British English |
| Analyze | Analyse |
| Analyzes | Analyses |
| Analyzed | Analysed |
| Analyzing | Analysing |
This pattern follows the same regional distinction seen in words such as traveling and travelling and fiber and fibre.
Examples:
- US: Scientists analyze data daily.
- UK: Scientists analyse data daily.
- US: The team analyzed customer feedback.
- UK: The team analysed customer feedback.
How Oxford, Dictionaries, And Style Guides Treat Analyse And Analyze
Major dictionaries recognize both spellings.
Oxford English Dictionary acknowledges both forms but traditionally associates analyse with British English.
American dictionaries generally list analyze as the standard spelling.
Style guides typically recommend one key rule:
Be consistent throughout your document.
If you’re writing for an American audience, stick with analyze, analyzed, and analyzing. Mixing spellings can appear careless or unprofessional.

Side-By-Side Sentence Comparisons Using Analyzed And Analysed
Comparing both spellings side by side makes the difference easier to see.
| American English | British English |
| We analyzed the market trends. | We analysed the market trends. |
| She analyzed the report carefully. | She analysed the report carefully. |
| The data was analyzed yesterday. | The data was analysed yesterday. |
| Experts analyzed the results. | Experts analysed the results. |
Notice that only the spelling changes. The sentence structure and meaning stay the same.
Why The Analyzed Vs Analysed Spelling Difference Exists
The distinction traces back to historical spelling reforms.
American English gradually adopted simplified spellings in many words. This movement was influenced by lexicographer Noah Webster, who advocated spellings that differed from British conventions.
As a result, American English commonly uses:
- Analyze
- Organize
- Recognize
British English often prefers:
- Analyse
- Organise
- Recognise
The same historical process explains spelling differences like plow and plough and whisky and whiskey.
Analyzed, Analysed, And Analysis Compared
Many writers confuse these forms because they look similar.
| Word | Function |
| Analyze | Verb (US) |
| Analyse | Verb (UK) |
| Analyzed | Past tense verb (US) |
| Analysed | Past tense verb (UK) |
| Analysis | Noun |
Examples:
- Correct: We analyzed the data.
- Correct: We analysed the data.
- Correct: The analysis was completed yesterday.
Incorrect:
- We analysis the data.
- The analyzed was finished yesterday.
A useful tip is that analysis keeps the same spelling in both American and British English.
