Which Spelling Should You Use?
Choose the spelling that matches your audience and required writing style.
Use Analyze for an American Audience
Use analyze when writing for:
- US websites
- American schools
- US universities
- American companies
- US publications
- American clients
- General US readers
If your website targets readers in the United States, analyze is the correct choice.
Use Analyse for a British Audience

- UK websites
- British schools
- UK universities
- British companies
- British publications
- General UK readers
British editors may change analyze to analyse when a document follows standard British spelling.
Follow the Required Style
Your location does not always determine the spelling.
A British writer producing content for an American company should normally use analyze. An American writer working for a British publisher may be expected to use analyse.
The audience, organization, publisher, or style guide should determine the final choice.
Why People Confuse Analyse and Analyze
The words are easy to confuse because they differ by only one letter.
Analyse contains an s, while analyze contains a z.
Online readers may encounter both forms because websites, books, social posts, and publications use different regional standards. Someone may read an American article using analyze and then see analyse in a British publication.
The related words analysis, analyses, and analyzes create additional confusion because their spellings and grammatical roles differ.
Analysis vs Analyse vs Analyze
These words are related, but they do not serve the same grammatical function.
Analysis
Analysis is a noun.
It refers to the process or result of examining something carefully.
Correct:
- The report includes a detailed analysis.
- Her analysis identified several weaknesses.
- We completed an analysis of the data.
Analysis is used in both American and British English.
Analyze
Analyze is the American verb.
It describes the action of examining something.
Correct in American English:
- We need to analyze the results.
- The researcher analyzed the evidence.
Analyse
Analyse is the British verb.
It performs the same function as analyze.
Correct in British English:
- We need to analyse the results.
- The researcher analysed the evidence.
The basic rule is:
- Analysis: Noun
- Analyze: American verb
- Analyse: British verb
Analyses vs Analyzes
Analyses and analyzes look similar, but their meanings and uses may differ.
Analyses as a Plural Noun
Analyses is the plural form of analysis in both American and British English.
- One analysis
- Two analyses
- Several analyses
The report may contain several analyses of the same issue.
Analyses as a British Verb
In British English, analyses can also be the third-person singular form of analyse.
It is used with subjects such as he, she, it, the program, or the company.
The surrounding sentence shows whether analyses is functioning as a plural noun or a verb.
Analyzes as an American Verb
In American English, analyzes is the third-person singular form of analyze.
It is always a verb.
The key distinction is:
- Analyses: Plural noun in both varieties or British verb
- Analyzes: American verb
Do Analyse and Analyze Have the Same Pronunciation?
Yes. Analyse and analyze are normally pronounced the same way.
The pronunciation sounds approximately like:
AN-uh-lyze
The final syllable rhymes with eyes.
The spelling difference does not create a different pronunciation.
Is One Spelling More Formal?
No. Analyse is not more formal than analyze, and analyze is not more modern or more technical than analyse.
Both words can appear in casual, professional, academic, literary, scientific, and technical writing.
The choice depends on regional spelling rather than formality.
What About Canadian English?
Canadian English uses a mixture of British and American spelling patterns.
Both analyse and analyze may appear in Canadian writing, depending on the publication, school, company, or style guide.
Canadian writers should follow the required house style rather than assuming that one form is always correct.
Consistency remains more important than personal preference.
What About Australian English?
Australian English generally follows British spelling conventions, so analyse is normally preferred.
Common Australian forms include:
- Analyse
- Analyses
- Analysed
- Analysing
However, organizations may follow their own editorial rules. Writers should check the required style before submitting formal work.
What About Oxford Spelling?
Oxford spelling uses z in many verbs that other British styles write with s. For example, Oxford-style writing may prefer organize instead of organise.
However, analyse is generally treated as an exception.
Oxford-style British writing normally retains:
- Analyse
- Analysed
- Analysing
Writers should not assume that every British -ise verb changes to -ize under Oxford spelling.
Can You Mix Analyse and Analyze?
You should not mix the two spellings in ordinary original writing.
A document that switches between analyse, analyze, analysed, and analyzing may look careless or poorly edited.
For American English, use the complete American set:
- Analyze
- Analyzes
- Analyzed
- Analyzing
For British English, use the complete British set:
- Analyse
- Analyses
- Analysed
- Analysing
Choose one system and apply it consistently throughout the article, report, email, or assignment.
When Mixed Spelling Is Acceptable
Mixed spelling may be acceptable when preserving original material.
Do not change spelling inside:
- Direct quotations
- Book titles
- Article titles
- Company names
- Product names
- Official document titles
- Published research titles
- Legal names
A quotation from a British source may contain analyse even when the rest of an American article uses analyze.
Preserving the original wording is more important than forcing every quoted term to match your preferred spelling.
When One Spelling Looks Wrong
A spelling can be correct English but still look inappropriate in a specific document.
Analyse may appear unusual in an American school assignment, business report, or website. A US spelling checker may flag it because the document is set to American English.
Similarly, analyze may be changed by a British editor when a document is expected to follow UK spelling.
The word is not universally wrong. It is simply inconsistent with the chosen regional style.
Common Mistakes and Corrections
Mistake 1: Believing the Meanings Are Different
Incorrect idea:
Analyse means a deeper examination than analyze.
Correction:
Both spellings have exactly the same meaning. Choose according to regional English, not the depth of the examination.
Mistake 2: Using Analyse as a Noun
Incorrect:
We completed an analyse of the problem.
Correct:
We completed an analysis of the problem.
Neither analyse nor analyze is the standard noun. The noun is always analysis.
Mistake 3: Spelling Analysis With a Z
Incorrect:
Her analyzis was detailed.
Correct:
Her analysis was detailed.
The noun analysis uses s in both American and British English.
Mistake 4: Mixing Regional Verb Forms
Inconsistent:
The team analysed the first report and is now analyzing the second.
Consistent American style:
The team analyzed the first report and is now analyzing the second.
Consistent British style:
The team analysed the first report and is now analysing the second.
Mistake 5: Confusing Analyses With Analyzes
Remember:
- Analyses may be a plural noun.
- Analyses may also be a British verb.
- Analyzes is an American verb.
The sentence structure and regional style reveal the correct meaning.
Mistake 6: Changing Spelling Inside a Quotation
Do not silently replace analyse with analyze inside a direct quotation from a British writer.
Quotations should preserve their original spelling unless an editorial note clearly explains the change.
Mistake 7: Choosing Based on Personal Location Only
A writer living in the United Kingdom may still need analyze when producing content for an American audience.
The target reader and required style are more important than the writer’s location.
Examples of Analyze in American English
- Doctors analyze test results before making a diagnosis.
