Quick Answer: 

Analyzing is correct in American English, while analysing is correct in British English.

Spelling	English Variety	Base Verb	Meaning
Analyzing	American English	Analyze	Examining something carefully
Analysing	British English	Analyse	Examining something carefully

So, if you’re writing for a US audience, use analyzing.

If you’re following British English, use analysing.

Neither spelling is a mistake when used within its appropriate English variety.

What Does Analyzing Mean?

Analyzing means examining something carefully to understand it, identify important details, or reach a conclusion.

You can analyze almost anything that requires careful examination. Students analyze literature. Scientists analyze data. Businesses analyze sales figures. Engineers analyze systems and researchers analyze evidence.

For example:

• The scientist is analyzing the test results.
• She spent several hours analyzing the report.
• The company is analyzing customer feedback.
• Students are analyzing the poem.
• Researchers are analyzing the collected data.

In each sentence, analyzing describes the action of examining something in detail.

The word comes from the American English verb analyze.

Examples of Analyzing in American English

Here are several examples that use the standard US spelling:

• The team is analyzing the sales data.
• She is analyzing the evidence carefully.
• The researcher spent weeks analyzing the results.
• We are analyzing customer responses.
• The students are analyzing the main character.
• The software is analyzing the available information.

The important spelling feature is the z.

Analyze → Analyzing

That pattern applies throughout American English.

What Does Analysing Mean?

Analysing has the same meaning as analyzing. It means examining something carefully to understand its details or meaning.

The only difference is that British English spells the base verb as analyse.

Therefore:

Analyse → Analysing

For example:

• The researcher is analysing the data.
• She is analysing the evidence.
• The students are analysing the novel.
• The company is analysing its financial results.

If you’re reading British English, you’ll see the s spelling frequently.

Examples of Analysing in British English

Consider these sentences:

• The scientist is analysing the samples.
• They are analysing the causes of the problem.
• She spent the afternoon analysing the report.
• Researchers are analysing the survey results.
• The students are analysing the poem.

These sentences mean exactly the same thing as their American English versions.

What’s the Difference?

The difference between analyzing and analysing is primarily regional spelling.

American English uses analyze.

British English uses analyse.

That difference carries into the -ing form.

Feature	Analyzing	Analysing
English variety	American	British
Base verb	Analyze	Analyse
Spelling	Z	S
Meaning	Same	Same
Grammatical function	Present participle or gerund	Present participle or gerund
Past tense	Analyzed	Analysed

The pronunciation doesn’t fundamentally change because of the spelling. A British reader and an American reader understand the same action.

The Base Verb Makes the Spelling Easy

Instead of trying to memorize both words separately, remember their base forms.

American English:

Analyze → Analyzing

British English:

Analyse → Analysing

Once you know the base verb, the correct -ing form follows naturally.

Why Does American English Use “Analyzing”?

American English generally uses analyze with a z. Consequently, the present participle becomes analyzing.

This spelling difference belongs to a broader pattern found in some words that use -ize or related endings in American English and -ise or related endings in British English.

For example:

American English	British English
analyze	analyse
analyzing	analysing
analyzed	analysed
organize	organise
organizing	organising
recognize	recognise
recognizing	recognising

However, English spelling isn’t perfectly mechanical. Not every word ending in -ise follows a simple US-to-UK conversion rule.

For analyze, though, the distinction is clear.

If your writing follows American English conventions, analyzing is the form to use.

In American English

When you’re writing in US English, choose analyzing.

This applies to academic writing, business documents, websites, reports, emails, technical material, and everyday communication.

For example:

The research team is analyzing the survey results.

Another example:

The manager spent the morning analyzing the company’s sales figures.

Both sentences follow standard American spelling.

Using analysing in American English won’t normally prevent readers from understanding your meaning. However, it can make the spelling look inconsistent if the rest of your writing follows American conventions.

For instance, a document might use:

• organizing
• recognizing
• analyzing
• analyzing

If one sentence suddenly contains analysing, the British spelling may stand out.

Correct American English Examples

Here are some practical examples:

• The doctor is analyzing the test results.
• The team is analyzing customer behavior.
• Researchers are analyzing the survey responses.
• The student is analyzing the author’s argument.
• Engineers are analyzing the structure.
• The company is analyzing its monthly expenses.

For US English, analyzing is the spelling worth remembering.

In British English

British English uses analysing because the base verb is analyse.

The spelling follows the same pattern:

Analyse → Analysing

For example:

The researchers are analysing the results.

The American version would use analyzing instead.

Neither sentence has a different meaning. The writer simply follows a different regional spelling convention.

Correct British English Examples

• The researchers are analysing the evidence.
• She is analysing the results.
• The company is analysing customer feedback.
• Students are analysing the text.
• Scientists are analysing the samples.

This spelling is perfectly standard in British English.

Analyze vs. Analyse

Understanding analyze vs. analyse makes the entire spelling issue much easier.

Analyze is the American English form.

Analyse is the British English form.

Both are verbs meaning to examine something carefully.

Word Form	American English	British English
Base verb	Analyze	Analyse
-ing form	Analyzing	Analysing
Past tense	Analyzed	Analysed
Past participle	Analyzed	Analysed
Noun	Analysis	Analysis

Notice something important: analysis remains the same in both varieties.

That means you don’t need to change every related word when switching between American and British English.

Analyzed vs. Analysed

The same regional difference appears in the past tense.

American English uses analyzed.

British English uses analysed.

For example:

American English:

The researchers analyzed the data.

British English:

The researchers analysed the data.

Both sentences describe the same action.

The difference follows directly from the base verbs:

Analyze → Analyzed

Analyse → Analysed

This pattern gives you a useful shortcut. If you’re using analyzing, you’ll generally use analyzed as the corresponding past form in American English.

Which Is More Correct?

Neither spelling is universally more correct.

The correct choice depends on the English variety.

Analyzing is correct for American English.

Analysing is correct for British English.

Calling analysing a spelling mistake without considering the variety of English would be misleading. British publications, schools, and writers routinely use it.

Likewise, analyzing is the normal spelling in American English.

The real rule is simple: match the spelling to your chosen English variety and stay consistent.

Common Mistakes 

A few mistakes appear repeatedly when people use these words.

Mixing American and British Spellings

One common problem is mixing spelling systems in the same document.

For example:

The team is analyzing the data and organising the information.

Here, analyzing follows American spelling while organising follows British spelling.

For consistent American English, write:

The team is analyzing the data and organizing the information.

The issue isn’t comprehension. It’s consistency.

Using “Analyzis”

Analyzis is not the standard spelling of the noun.

The correct word is analysis.

For example:

The report includes a detailed analysis of the results.

Its plural form is analyses:

The researchers conducted several analyses.

These forms can look confusing because they don’t follow the same spelling pattern as analyze and analyzing.

Confusing the Verb and Noun

The words analyze, analyzing, and analysis belong to the same family. However, they serve different grammatical purposes.

Word	Function	Example
Analyze	Verb	We need to analyze the data.
Analyzing	Present participle/gerund	She is analyzing the data.
Analyzed	Past tense/past participle	They analyzed the data.
Analysis	Singular noun	The analysis revealed a problem.
Analyses	Plural noun	Several analyses confirmed the result.

A useful question is: Are you naming the examination or describing the action?

If you’re naming it, analysis may be the right choice.

If you’re describing the action, you may need analyze or analyzing.

 Examples Side by Side

The clearest way to see the difference is to compare identical sentences.

American English	British English
She is analyzing the data.	She is analysing the data.
We are analyzing the results.	We are analysing the results.
He spent hours analyzing the report.	He spent hours analysing the report.
The team is analyzing customer feedback.	The team is analysing customer feedback.
Scientists are analyzing the samples.	Scientists are analysing the samples.
Students are analyzing the evidence.	Students are analysing the evidence.
She enjoys analyzing historical documents.	She enjoys analysing historical documents.
The company is analyzing its sales figures.	The company is analysing its sales figures.
Researchers are analyzing survey responses.	Researchers are analysing survey responses.
The software is analyzing the information.	The software is analysing the information.

The message stays the same in every pair.

Only the regional spelling changes.

How to Remember the Difference

There’s no need for a complicated memory trick.

Just remember the base verbs:

American English:
Analyze → Analyzing

British English:
Analyse → Analysing

Think of the z in American analyze as carrying into analyzing.

Likewise, the s in British analyse carries into analysing.

You can also remember the complete forms together:

• Analyze → Analyzing → Analyzed
• Analyse → Analysing → Analysed

One detail deserves special attention: the noun is analysis in both varieties.

Its plural is analyses.

So don’t write analyzis when you mean the noun.

Which Spelling Should You Use?

The answer depends on your audience.

Use “Analyzing” When…

Choose analyzing if:

• You’re writing in American English.
• Your readers primarily use US English.
• You’re following an American style guide.
• You’re writing for a US-based publication.
• Your document already uses American spellings such as organizing and recognizing.

For example:

The researchers are analyzing the evidence before publishing their findings.

That’s the standard US form.

Use “Analysing” When…

Choose analysing if:

• You’re writing in British English.
• Your readers primarily use UK English.
• You’re following British spelling conventions.
• Your school, employer, or publication requires British English.
• The surrounding document consistently uses British spellings.

For example:

The researchers are analysing the evidence before publishing their findings.

The meaning remains unchanged.

What If You Write for an International Audience?

If your readers come from different English-speaking regions, pick one spelling system and use it consistently.

For a website that follows US English, use analyzing.

For a publication that follows British English, use analysing.

Don’t alternate between the two simply because both forms are familiar.

Consistency gives your writing a cleaner rhythm and makes your chosen style obvious.
