Analyses or Analysis: Which Spelling Is Correct? A Simple Guide

Have you ever stopped while writing and wondered whether to use analyses or analysis? You are not alone. Many students, writers, teachers, and business workers face this question when they write reports, emails, essays, or research papers.

Both words are correct. The key is to know when to use each one. Analysis is the singular form. It means one close study of a topic, problem, or set of facts. Analyses is the plural form. It means more than one such study.

The confusion often comes from the unusual spelling change. Most English nouns form their plural by adding -s or -es. However, analysis changes to analyses. The final letters and the way we say the word also change.

This guide explains the difference between analyses and analysis in simple English. You will learn their meanings, origins, spelling rules, and correct use in daily writing. You will also see examples, compare British and American English, and learn which form fits your audience.

Whether you are writing a school essay, a work email, or a formal report, this guide will help you choose the right word with confidence.

Analyses or Analysis Quick Answer

Both analysis and analyses are correct English words, but they have different meanings.

• Analysis is singular. Use it when you mean one study or review.
• Analyses is plural. Use it when you mean two or more studies or reviews.

Simple examples

• Correct: The analysis shows a clear trend.
• Correct: The analyses show different trends.
• Correct: Our team completed one analysis.
• Correct: Our team completed three analyses.

How to remember the difference

Think of the words this way:

Word	Number	Example
Analysis	One	This analysis is useful.
Analyses	More than one	These analyses are useful.

Easy rule: Use analysis for one and analyses for more than one.

The meaning does not change based on British or American English. Both forms are standard in both varieties.

The Origin of Analyses or Analysis

The word analysis has a long history. It comes from the Greek word analysis, which refers to breaking something apart or loosening it. The word later entered Latin and then English.

Its core meaning is still linked to the same idea: looking closely at something by breaking it into smaller parts. For example, a writer may study the parts of a story, while a scientist may study data to find a pattern.

The plural form, analyses, follows a pattern found in several words that came from Greek. These words do not always form their plurals by simply adding -s.

Here are a few examples:

Singular	Plural
Analysis	Analyses
Thesis	Theses
Crisis	Crises
Diagnosis	Diagnoses
Hypothesis	Hypotheses

Notice the change from -sis to -ses. This pattern can seem unusual because many other English nouns use a simpler plural ending.

The spelling difference is not a regional rule. It comes from the word’s history and its established form in English.

Today, analysis and analyses are used in many fields, including science, business, education, economics, and technology.

British English vs American English Spelling

One common question is whether British and American English use different spellings for analysis and analyses.

The answer is simple: there is no spelling difference between British and American English for these two words.

Both varieties use analysis for the singular and analyses for the plural. The main difference is pronunciation, not spelling.

Comparison table

Feature	British English	American English
Singular	Analysis	Analysis
Plural	Analyses	Analyses
Singular example	This analysis is clear.	This analysis is clear.
Plural example	These analyses are useful.	These analyses are useful.
Main difference	Often pronounced with a broad final vowel	Often pronounced with a flatter final vowel

Pronunciation varies by speaker and accent. In both varieties, the singular usually ends with an “sis” sound. The plural usually ends with an “seez” sound.

Examples in both varieties

British English:
The research team published two analyses of the data.

American English:
The research team published two analyses of the data.

Both sentences are correct.

Do not confuse this word pair with words such as colour and color, or organise and organize. Those words have common regional spelling differences. Analysis and analyses do not.

The best approach is to focus on number and meaning rather than location.

Which Spelling Should You Use?

The right choice depends on how many studies, reviews, or examinations you mean. Your audience may affect your writing style, but it does not change the spelling rule.

For US readers

Use analysis for one study and analyses for more than one. Follow the style guide used by your school, company, or publication.

Examples:

• The financial analysis is complete.
• The analysts prepared separate analyses for each company.

For UK and Commonwealth readers

Use the same rule. British, Australian, Canadian, and other Commonwealth English readers will understand both forms in their correct contexts.

Examples:

• This analysis covers the main findings.
• The researchers compared several analyses.

For a global audience

Choose the correct form based on number. Keep your sentences short and clear, especially when writing for readers who speak English as a second language.

For example:

• Instead of The analyses is ready, write The analysis is ready if you mean one study.
• Instead of The analysis are ready, write The analyses are ready if you mean more than one study.

For academic and professional writing

Always check whether you are referring to one report or several separate studies. A report may contain several sections of analysis without requiring the plural word analyses.

For example, The report includes an analysis of costs and an analysis of risks describes two studies. You could also write The report includes two analyses.

The goal is to make your meaning clear and your grammar correct.

Common Mistakes with Analyses or Analysis

Many errors happen because writers treat analyses as if it were just another spelling of analysis. The two forms have different grammatical roles.

Mistake 1: Using a plural verb with analysis

Incorrect: The analysis are complete.

Correct: The analysis is complete.

Why? Analysis is singular, so it takes a singular verb.

Mistake 2: Using a singular verb with analyses

Incorrect: The analyses is complete.

Correct: The analyses are complete.

Why? Analyses is plural, so it takes a plural verb.

Mistake 3: Adding a regular plural ending

Incorrect: Analysises

Correct: Analyses

The word has an irregular plural form. Do not add another -es.

Mistake 4: Confusing spelling and pronunciation

Analysis and analyses look similar, but they are not pronounced in the same way.

• Analysis: usually ends with a “sis” sound.
• Analyses: usually ends with a “seez” sound.

Learning the sound difference can help you remember which form you need.

Mistake 5: Using analyses for one study

Incorrect: This analyses explains the results.

Correct: This analysis explains the results.

Use analysis when you mean one study.

Mistake 6: Using analysis for several studies

Incorrect: The two analysis reached different conclusions.

Correct: The two analyses reached different conclusions.

Use analyses when you mean more than one study.

Mistake 7: Forgetting subject-verb agreement

Incorrect: The analyses shows a new pattern.

Correct: The analyses show a new pattern.

Remember that a plural subject usually takes the base form of the verb in the present tense.

Analyses or Analysis in Everyday Examples

Knowing the rule is helpful, but seeing the words in real situations makes them easier to use.

1. In emails

Use analysis when referring to one review or report.

Example:

Subject: Sales Analysis

Hi team,

Please review the sales analysis attached to this email. It covers our results for the last month.

Best regards,
Alex

Use analyses when discussing several reviews.

Example:

We have received three analyses from the research team. Please read them before Friday’s meeting.

2. In news writing

News reports often use analysis when describing one expert’s review of an event.

Example:

The expert’s analysis explains why prices have increased.

Use analyses when comparing several studies or expert reviews.

Example:

New analyses suggest that the trend may continue next year.

3. On social media

Social media posts often use short, direct sentences.

Examples:

• My analysis of the game is now online.
• Here are three analyses of the latest match.
• This analysis explains the main problem in simple terms.

The same grammar rules apply to posts, captions, and comments.

4. In academic writing

Academic work often includes both forms.

Examples:

• This analysis examines the effects of climate change.
• The researchers conducted two analyses of the survey results.
• Our analysis supports the main argument.
• The statistical analyses revealed several patterns.

Use the singular form for one study and the plural form for separate studies.

5. In business reports

Business teams may study sales, costs, risks, or customer behavior.

Examples:

• The cost analysis shows where we can save money.
• The team completed separate analyses of sales and customer feedback.
• Our analysis suggests that demand will rise.
• The financial analyses offer different views of the market.

These examples show why the correct form matters. It tells readers whether you mean one review or several.

Analyses or Analysis Google Trends and Usage Data

People often search for analyses or analysis because they want a quick grammar answer. Students may need help with homework, while professionals may want to avoid mistakes in reports and emails. Writers and editors may also search for the difference when checking a document.

Which form is more common?

In everyday English, analysis is widely used because people often talk about one process, report, or review. The plural form analyses appears when writers compare separate studies, reports, or sets of findings.

However, frequency depends on the topic. Research papers, scientific articles, and data reports may use analyses more often than casual messages do.

What about Google Trends?

Google Trends shows relative search interest over time and across locations. It does not provide a direct count of every time a word appears in writing or speech.

A search for analysis may reflect interest in the concept itself, while analyses or analysis may reflect a grammar question. These are different search intents, so their figures should not be treated as a direct measure of spelling correctness.

Without a live Google Trends comparison, it would not be reliable to name a winning country, give exact percentages, or claim a specific change in popularity.

How does usage vary by context?

Context	Likely use	Example
Schoolwork	Both	A literary analysis; two text analyses
Business	Both	A market analysis; several market analyses
Science	Both	An analysis of a sample; repeated analyses
News	Often analysis	An analysis of the election
Grammar searches	Both terms	Analyses or analysis: which is correct?

The important point is that search popularity and correct usage are not the same thing. A word can be searched more often without being the right choice in every sentence.
