Analyse vs. Analyze: Quick Comparison Table

Word	English variety	Meaning	Example
analyse	British English	examine carefully	We need to analyse the results.
analyze	American English	examine carefully	We need to analyze the results.

The difference is primarily regional spelling, not meaning.

What Does “Analyse” Mean?

Analyse is the British English spelling of the verb meaning to examine something carefully in order to understand it, explain it, or discover important information about it.

Scientists analyse the data before publishing their findings.

The teacher asked students to analyse the poem.

We need to analyse the causes of the problem.

The spelling analyse is common in British English and is also used in other English varieties influenced by British spelling conventions.

What Does “Analyze” Mean?

Analyze is the American English spelling of the same verb.

Scientists analyze the data before publishing their findings.

The teacher asked students to analyze the poem.

We need to analyze the causes of the problem.

The meaning is exactly the same as analyse.

Analyse or Analyze: British vs. American English

The main difference is the English variety being used.

British English

British English generally uses:

analyse

For example:

Researchers analyse survey responses.

American English

American English uses:

analyze

For example:

Researchers analyze survey responses.

This follows a broader spelling pattern in which many verbs ending in -ise in British English are commonly spelled with -ize in American English.

Examples of the same pattern

British English	American English
analyse	analyze
organise	organize
recognise	recognize
realise	realize
apologise	apologize

However, spelling conventions can vary by dictionary and style guide, so it is important not to assume that every word ending in -ise has exactly the same regional treatment.

Is “Analyse” or “Analyze” More Correct?

Neither is universally more correct.

Analyse is correct when you are following British English spelling.

Analyze is correct when you are following American English spelling.

For example:

British English: The researchers analyse the evidence.

American English: The researchers analyze the evidence.

Both sentences are grammatically correct and communicate the same meaning.

The important issue is consistency. If your document follows British English, use analyse throughout. If it follows American English, use analyze throughout.

Analyse or Analyze in Academic Writing

Both spellings can appear in academic writing, depending on the English variety required by the institution, journal, publisher, or style guide.

If your academic work follows British English:

This study will analyse the relationship between income and education.

If it follows American English:

This study will analyze the relationship between income and education.

Before submitting academic work, check the required style guide rather than changing spellings randomly.

Analyse or Analyze in Different Countries

English spelling conventions differ across countries.

Analyse is commonly used in British English and is also found in countries and institutions that follow British spelling conventions.

Analyze is standard in American English.

For international writing, the safest approach is to identify your target audience and follow the spelling convention expected by that audience.

For example:

• A British publication may prefer analyse.
• An American publication may prefer analyze.
• A company serving both markets may choose one style guide and apply it consistently.

Grammar of Analyse and Analyze

Both words are verbs.

Present tense

British English:

I analyse the results.

American English:

I analyze the results.

Third-person singular

British English:

She analyses the evidence.

American English:

She analyzes the evidence.

Notice that the endings change slightly:

• analyse → analyses
• analyze → analyzes

Past tense

British English:

They analysed the results.

American English:

They analyzed the results.

Present participle

Both varieties use:

analysing / analyzing

Examples:

She is analysing the data.

She is analyzing the data.

Analyse, Analyze, and Analysis

One important point is that the noun is spelled analysis in both British and American English.

The analysis was detailed.

The plural is:

analyses

For example:

The researchers conducted several analyses.

So the spelling difference appears mainly in the verb:

• British: analyse
• American: analyze
• Noun in both: analysis
• Plural noun in both: analyses

This can make the word family slightly confusing.

Analyse vs. Analyze Word Forms

Function	British English	American English
Base verb	analyse	analyze
Third-person singular	analyses	analyzes
Past tense	analysed	analyzed
-ing form	analysing	analyzing
Noun	analysis	analysis
Plural noun	analyses	analyses

Example

British English:

She analysed the data and presented her analysis.

American English:

She analyzed the data and presented her analysis.

Both are correct.

Pronunciation of Analyse and Analyze

Analyse and analyze are pronounced the same in standard English.

The spelling difference does not normally create a difference in pronunciation.

Approximate pronunciation:

analyse / analyze — /ˈænəlaɪz/

The stress falls on the first syllable.

The noun analysis has a different ending and pronunciation:

analysis — /əˈnæləsɪs/

So remember:

• analyse / analyze → verb
• analysis → noun

Common Mistake: Mixing the Spelling Systems

One common problem is inconsistent spelling.

For example:

The researchers analysed the data and organized the results.

This mixes British analysed with American organized.

That does not necessarily make the sentence impossible to understand, but it creates an inconsistent spelling style.

If you are using British English, you might write:

The researchers analysed the data and organised the results.

If you are using American English:

The researchers analyzed the data and organized the results.

The key principle is consistency.

Analyse or Analyze in Formal Writing?

Both are appropriate in formal writing.

Choose according to your intended variety of English.

British English

The researchers analysed the results using statistical methods.

American English

The researchers analyzed the results using statistical methods.

Neither version is less formal.

The difference is spelling convention, not level of formality.

Analyse vs. Analyze: Memory Trick

A simple way to remember the difference is:

British English → -ise

analyse
organise
recognise

American English → -ize

analyze
organize
recognize

Think:

British = analyse
American = analyze

The meaning remains the same.

What Major Dictionaries Say

Major English dictionaries recognize analyse and analyze as variants of the same verb.

British-oriented dictionaries commonly list analyse, while American dictionaries use analyze as the standard spelling.

The distinction is therefore not between a correct and an incorrect word. It is primarily a matter of regional spelling convention.

Analyse and analyze are both correct.

Use analyse when writing in British English:

We need to analyse the results.

Use analyze when writing in American English:

The two words have the same meaning and pronunciation. The main difference is their spelling convention.

British English → analyse
