Analyze vs analyse: Both spellings are correct, and they have the same meaning. The difference is regional spelling: analyze is the standard spelling in American English, while analyse is the standard spelling in British English and many other varieties of English, including Australian and New Zealand English. Both words mean to examine something carefully to understand its parts, meaning, structure, or results.
Quick Answer: Analyze vs Analyse

- American English: Scientists analyze the results of the experiment.
- British English: Scientists analyse the results of the experiment.

Neither spelling is inherently incorrect. The best choice depends on your intended audience and the spelling style you are following. Whichever form you choose, use it consistently throughout your writing.

The Core Rule: American English vs British English
The main difference between analyze and analyse is the spelling convention used in different varieties of English.
| Feature | Analyze | Analyse |
|---|---|---|
| Preferred variety | American English | British English |
| Meaning | Examine carefully | Examine carefully |
| Part of speech | Verb | Verb |
| Pronunciation | Same | Same |
| Example | Analyze the evidence. | Analyse the evidence. |
| Correct in its main variety? | Yes | Yes |
The rule is simple: use analyze for American English and analyse for British English.
If you are writing for a US audience, choose analyze. If you are writing for a UK audience, choose analyse. For international audiences, either can work, provided you follow one consistent spelling style.
Why Do Analyze and Analyse Have Different Spellings?
The difference comes from the development of American and British spelling conventions. American English often uses -ize in words where British English commonly uses -ise.
Examples include:
| American English | British English |
|---|---|
| Analyze | Analyse |
| Paralyze | Paralyse |
| Organize | Organise |
| Recognize | Recognise |
| Realize | Realise |
| Apologize | Apologise |
These patterns are common, but spelling conventions can vary. In particular, -ize is also accepted in some British English styles, including Oxford spelling. Therefore, it is not accurate to say that every British publication must use -ise.
For analyze, the distinction is especially straightforward: American English normally uses analyze, while British English commonly uses analyse.
Analyze vs Analyse: Incorrect and Correct Examples
Because both spellings are valid, the following examples focus on matching spelling to the intended style rather than treating one form as universally wrong.
| Writing context | Preferred spelling | Example |
|---|---|---|
| American school assignment | Analyze | Students analyze the passage. |
| British school assignment | Analyse | Students analyse the passage. |
| US business report | Analyze | We analyze quarterly sales. |
| UK business report using -ise spelling | Analyse | We analyse quarterly sales. |
| American scientific paper | Analyze | The researchers analyze the samples. |
| British scientific paper using -ise spelling | Analyse | The researchers analyse the samples. |
| US website | Analyze | Learn how to analyze your results. |
| UK website using British spelling | Analyse | Learn how to analyse your results. |
| American academic essay | Analyze | The essay will analyze the author’s argument. |
| British academic essay using -ise spelling | Analyse | The essay will analyse the author’s argument. |
Common Spelling Mistakes
- Incorrect for standard American spelling: “The team will analyse the data.”
Preferred American form: “The team will analyze the data.” - Inconsistent British-style writing: “We analyse the results and then analyze the findings.”
Better: “We analyse the results and then analyse the findings.”
The first example is not grammatically wrong in all English varieties; it simply uses the spelling more commonly associated with British English in an American context. Consistency is the important principle.

How to Use Analyze and Analyse Correctly
In Academic Writing
Use the spelling expected by your institution, instructor, journal, or style guide.
- American English: The researcher will analyze the survey results.
- British English: The researcher will analyse the survey results.
In Business Writing
Follow the spelling conventions used by your company or target audience.
- American English: Our team will analyze customer feedback.
- British English: Our team will analyse customer feedback.
In SEO Content and Blog Writing
Choose the spelling based on your target audience and use it consistently across headings, body text, and related content.
For example, an article aimed primarily at US readers would normally use analyze, while one aimed at UK readers would commonly use analyse.
A keyword may have a particular regional spelling, so consider the intended search audience when choosing your primary form.
In Scientific and Technical Writing
Both forms are used by English-language publications. The required spelling depends on the publisher’s style guide, not on a difference in scientific meaning.
- American style: The software will analyze the dataset.
- British style: The software will analyse the dataset.
Related Words: Analysis, Analytical, and Analyzing
The spelling difference between analyze and analyse does not apply equally to every related word.
| American English | British English | Meaning |
|---|---|---|
| Analyze | Analyse | To examine carefully |
| Analyzes | Analyses | Present-tense form for he, she, or it |
| Analyzed | Analysed | Past tense or past participle |
| Analyzing | Analysing | The -ing form |
| Analysis | Analysis | Examination of something |
| Analytical | Analytical | Relating to analysis |
| Analyst | Analyst | A person who performs analysis |
Be especially careful with analysis and analyses. They are not interchangeable:
- Analysis is singular: “The analysis is complete.”
- Analyses is the plural of the noun analysis: “The analyses are complete.”
- Analyses can also be the verb form used with he, she, or it: “She analyses the data.”
The noun analysis is spelled the same in American and British English. The plural noun analyses is also spelled the same in both varieties.
Why People Confuse Analyze and Analyse
1. Regional Spelling Differences
People who read American and British websites may encounter both forms. Since the meanings are identical, the different spellings can be confusing.
2. Similar Words Follow Different Patterns
Words such as organize/organise and recognize/recognise follow a similar regional pattern, but not every word follows exactly the same conventions.
3. Spellcheck Uses Different Language Settings
A spellchecker set to American English may flag analyse, while one set to British English may prefer it over analyze, depending on the dictionary and style settings.
4. Writers Mix English Variants
A document might use analyze in one paragraph and organise in another. This is usually a consistency issue rather than a grammatical error.
Common Mistakes Checklist
Before submitting your writing, check the following:
- Use analyze when following standard American English spelling.
- Use analyse when following British English spelling conventions that prefer -ise.
- Follow your employer’s, school’s, journal’s, or publisher’s style guide.
- Keep spelling consistent throughout the same document.
- Do not confuse analysis with analyses.
- Remember that both analyze and analyse have the same meaning.
- Do not assume that every British English style rejects -ize spellings; some, including Oxford spelling, use them.
- Set your word processor’s language preference to match your intended English variety.
Real-Life Situations: Analyze or Analyse?
Situation 1: Writing a US College Essay
Preferred: “This essay will analyze the character’s motivations.”
American English normally uses analyze.
Situation 2: Preparing a UK Business Report
Preferred in a British style using -ise spellings: “We will analyse the company’s performance.”
The spelling matches the document’s chosen convention.
Situation 3: Publishing a Scientific Paper
Correct: Follow the journal’s author guidelines.
Scientific publishers may require American English, British English, or a particular house style.
Situation 4: Writing Website Content for International Readers
Correct: Choose one style based on your main audience and apply it consistently.
If your audience is mixed, either form can be understood, but consistency makes the content more polished.
Situation 5: Editing an Existing Document
Correct: Check the document’s established spelling style before changing words.
Do not replace every analyse with analyze automatically if the document is written in British English.
