150+Analyses or Analysis: Which Word Is Correct (for 2026)

The correct choice between analyses or analysis depends on If you are talking about one examination of something or several. Analysis is the singular form, while analyses is the plural form. 

For example, you can write “This analysis is helpful” when discussing one study and “These analyses are helpful” when discussing several studies. The main challenge is spelling and pronunciation because both words look similar but serve different purposes.

 In this guide, you will learn the meaning of each word, how to use it correctly, the difference in pronunciation, and common mistakes to avoid. You will also find simple examples from school, work, science, and everyday life. By the end, you will know when to use analysis and when to use analyses in American English.

Quick Answer: Analyses or Analysis?

Analysis is singular, and analyses is plural. Use analysis when referring to one detailed study, review, or examination. Use analyses when referring to two or more studies, reviews, or examinations.

Word	Meaning	Example
Analysis	One study or examination	Her analysis is clear.
Analyses	Two or more studies or examinations	Her analyses are clear.

Here is an easy way to remember the difference:

• One = analysis. “The teacher completed one analysis.”
• More than one = analyses. “The teacher completed three analyses.”

Remember that analyses is not a spelling mistake. It is the standard plural form of analysis.

The word analysis means a careful study or examination of something to understand it better. You may analyze information, a problem, a piece of writing, a business, or a scientific result.

When you perform an analysis, you look at details, consider evidence, and try to understand what those details mean. Instead of simply looking at something, you examine it more closely.

For example, a student may read a story and explain its main idea, characters, and message. This work is an analysis of the story.

A business owner might study monthly sales to find out why profits have increased or decreased. This is a business analysis.

A scientist may examine test results to understand what they show. This is a scientific analysis.

The word is used in many fields, including education, science, business, health research, and literature.

Examples:

• The analysis of the report revealed an important problem.
• My teacher asked me to write an analysis of the poem.
• The company completed an analysis of its sales.
• A careful analysis can help us make better decisions.

In each sentence, analysis refers to one study or examination. That is why the singular form is correct.

What Does Analyses Mean?

Analyses is the plural form of analysis. It refers to two or more studies, examinations, or detailed reviews.

Use analyses when you are discussing several separate examinations, even if they all focus on the same subject.

For example, a doctor might review several test reports. Each report may contain a separate analysis. When discussing all of them together, you can use analyses.

Similarly, a company may study sales in different cities. If it completes one study for each city, it may refer to the results as several analyses.

Examples:

• The researchers published three analyses of the survey results.
• These analyses show different patterns in customer behavior.
• Our team compared the analyses before making a decision.
• The teacher collected the students’ analyses of the novel.
• Several analyses support the same conclusion.

Notice that analyses is often used with plural words such as these, those, several, and many.

The word also takes plural verbs in ordinary sentences. For example, you should write “The analyses are complete,” not “The analyses is complete.”

The key point is simple: when you mean more than one analysis, use analyses.

Analyses or Analysis: The Main Differences

Although these words share the same base, they have different grammatical roles. Understanding those roles will help you choose the correct word when writing essays, emails, reports, and blog posts.

Difference	Analysis	Analyses
Number	Singular	Plural
Meaning	One examination	More than one examination
Common article	An analysis	Analyses or some analyses
Demonstratives	This analysis, that analysis	These analyses, those analyses
Common verbs	Is, was, has	Are, were, have
Example	The analysis is complete.	The analyses are complete.

Consider these two sentences:

“The analysis was detailed.”

This sentence refers to one examination. The singular noun analysis agrees with the singular verb was.

“The analyses were detailed.”

This sentence refers to multiple examinations. The plural noun analyses agrees with the plural verb were.

The spelling difference is also important. Analysis ends in -sis, while analyses ends in -ses. This change is part of the standard plural form of this word.

Do not assume that adding just an s to analysis will produce the correct plural. The standard plural is analyses, not analysises.

How to Use Analysis Correctly in a Sentence

Use analysis when you mean one examination or study. The word can appear as the subject of a sentence, the object of a verb, or the object of a preposition.

Here are some common patterns.

Sentence pattern	Example
An analysis of something	An analysis of the data revealed a pattern.
The analysis of something	The analysis of the report took two hours.
A detailed analysis	We need a detailed analysis of the problem.
One analysis	The team completed one analysis.
This analysis	This analysis explains the main issue.

You will often see the word after verbs such as complete, conduct, perform, provide, and review.

For example:

• The manager will conduct an analysis of the company’s costs.
• The student completed an analysis of the short story.
• We need to review the analysis before publishing the report.
• Her analysis of the problem helped the team find a solution.
• This analysis provides useful information about customer needs.

The article a or an depends on the sound that follows it. Because analysis begins with a vowel sound, use an analysis, not a analysis.

Correct: “We prepared an analysis of the results.”

Incorrect: “We prepared a analysis of the results.”

You can also use analysis without an article when the noun is used in a general or uncountable-looking expression, depending on the sentence. For instance, “Analysis is an important part of research” describes the activity in general rather than one specific report.

Use analyses when you are referring to more than one examination. The plural noun usually takes plural verbs and can be used with numbers or plural expressions.

Examples:

• The two analyses reached similar conclusions.
• Several analyses were completed last week.
• These analyses are based on recent survey data.
• The researchers compared four analyses of the same issue.
• Both analyses provide useful evidence.

The word can also appear after phrases such as a series of or a number of, but pay attention to the noun that controls the sentence.

For example, “A series of analyses was published” treats series as the main subject. In contrast, “Several analyses were published” uses analyses as the plural subject.

This distinction can help you avoid subject-verb agreement errors.

Another useful point is that analyses can refer to separate studies of different subjects or multiple examinations of the same subject. The context tells readers which meaning you intend.

For example:

“The team prepared analyses of three marketing campaigns.”

This means that the team prepared multiple examinations, possibly one for each campaign.

“The team prepared three analyses of the same campaign.”

This means that the same campaign was examined in three separate ways or at three different times.

Both sentences are grammatically correct. The difference comes from the information surrounding the noun.

Why Is the Plural of Analysis Spelled Analyses?

The plural form analyses follows a pattern found in several English words that come from Greek. These nouns often change their endings instead of simply adding -s or -es.

For example, analysis becomes analyses. The change from -sis to -ses is a standard feature of this word’s plural form.

You can recognize a similar pattern in other words:

Singular	Plural	Meaning
Analysis	Analyses	Studies or examinations
Thesis	Theses	Formal arguments or research papers
Crisis	Crises	Serious problems or difficult situations
Basis	Bases	Foundations or starting points
Diagnosis	Diagnoses	Identifications of illnesses or problems

These examples help explain why analysises is not the correct plural spelling.

However, not every English word follows the same pattern. Some nouns form their plurals by adding -s, while others change their spelling in different ways. It is best to learn the common plural forms of frequently used words.

If you are unsure about a word, check a reliable dictionary rather than guessing based on how another word changes.

How to Pronounce Analysis and Analyses

The pronunciation is another important difference between these words. Although they look similar, they do not sound exactly the same.

In standard American English:

• Analysis: uh-NAL-uh-sis
• Analyses: uh-NAL-uh-seez

The final part of analysis sounds like “sis,” while the final part of analyses sounds like “seez.”

The first part of both words is pronounced in a similar way. The main difference comes at the end.

Try saying these sentences aloud:

“The analysis is ready.”

“The analyses are ready.”

Listen for the difference between analysis and analyses. Practicing with complete sentences can help you remember both the meaning and pronunciation.

You may also notice that the spelling change affects how the final syllable sounds. This is one reason the plural form can be confusing for English learners.

Do not worry if the words take some practice. Reading them aloud and using them in short sentences is a useful way to build confidence.

Analyses or Analysis in American English

Both analysis and analyses are correct in American English. The difference is grammatical number, not regional spelling.

American writers use analysis for one examination and analyses for multiple examinations. British English follows the same basic distinction.

For example, an American student might write:

“My analysis of the book explains the main character’s choices.”

If the student writes several separate examinations, the sentence could become:

“My analyses of the books explain the characters’ choices.”

The choice between these words does not depend on If your audience is American or British. It depends on If you mean one analysis or more than one.

This is different from spelling pairs such as color and colour, where regional conventions often determine the preferred spelling.

If your website targets readers in the United States, use standard American English throughout your article. However, do not replace analyses with analysis simply because you are writing for an American audience. Both forms are needed for correct grammar.

Common Mistakes When Using Analyses or Analysis

Even experienced writers sometimes confuse these words. The good news is that most mistakes can be fixed by checking If the sentence refers to one examination or several.

Mistake 1: Using analysis when you mean more than one

Incorrect: “The three analysis were useful.”

Correct: “The three analyses were useful.”

Because the sentence refers to three examinations, analyses is the correct choice.

Mistake 2: Writing analysises

Incorrect: “The team completed two analysises.”

Correct: “The team completed two analyses.”

Analysis has an irregular plural form. You cannot make the plural by simply adding -es to the complete singular word.

Mistake 3: Using a singular verb with analyses

Incorrect: “The analyses is complete.”

Correct: “The analyses are complete.”

Analyses is plural, so it normally takes a plural verb.

Mistake 4: Using a plural verb with analysis

Incorrect: “The analysis are ready.”

Correct: “The analysis is ready.”

Analysis is singular, so it normally takes a singular verb.

Mistake 5: Using the wrong article

Incorrect: “I wrote a analysis of the results.”

Correct: “I wrote an analysis of the results.”

Use an before analysis because the word begins with a vowel sound.

Mistake 6: Confusing the words when speaking

Some learners use analysis every time because it is the form they know best. However, when discussing multiple examinations, they should use analyses.

For example, “We reviewed five analyses” is correct, while “We reviewed five analysis” is incorrect.

A simple proofreading method is to look for number words such as one, two, three, several, and many. These words often reveal which form you need.

Examples from everyday situations can make the difference easier to understand. You will often encounter both words in schoolwork, business reports, research, and online writing.

In education

A student may write one analysis of a poem for an English class. If the student writes separate examinations of three poems, those are three analyses.

• My analysis of the poem explains its main message.
• The teacher reviewed all five analyses before giving feedback.

In business

A company may conduct an analysis to understand why sales have fallen. If it examines sales in several regions through separate studies, it may produce multiple analyses.

• Our analysis shows that sales dropped in July.
• The regional analyses reveal different customer needs.

In science

Researchers may analyze one sample or compare several separate sets of results.

• The analysis of the sample took one day.
• The analyses of the samples produced different results.

In literature

A reader can analyze a novel’s themes, characters, or writing style. Each separate examination may be called an analysis.

• Her analysis of the novel focuses on friendship.
• The students submitted their analyses of the two stories.

In everyday problem-solving

You might study your monthly spending to understand where your money goes. That is one analysis. If you separately examine spending, savings, and household bills, you may complete several analyses.

• My analysis helped me understand my spending habits.
• These analyses helped us compare our monthly costs.

These examples show that the same basic rule works in many situations. The subject may change, but the singular and plural distinction stays the same.

Analysis vs. Analyses: Which Word Should You Use?

When choosing between the two words, look at the meaning of the sentence first. Do not choose based only on how the word looks or sounds.

Use analysis when you are talking about one study or when referring to the general activity of examining something.

Use analyses when you are talking about two or more separate studies.

Here are some useful examples:

What you want to say	Correct wording	Why
One study of a report	An analysis of the report	One examination
Three studies of a report	Three analyses of the report	Multiple examinations
One study is finished	The analysis is finished.	Singular noun and verb
Multiple studies are finished	The analyses are finished.	Plural noun and verb
Studying information in general	Analysis helps us understand data.	General activity
Several studies show a pattern	The analyses show a pattern.	More than one study

Before you finalize your sentence, ask yourself three questions:

1. Am I talking about one examination or more than one?
2. Does the noun agree with the verb?
3. Have I spelled the word correctly?

For example, consider this sentence: “The analysis of the reports are complete.”

The word analysis is singular, but the verb are is plural. If you mean one combined examination, write “The analysis of the reports is complete.”

If you mean several separate examinations, write “The analyses of the reports are complete.”

Both corrected sentences are possible. Your intended meaning determines which one is right.

Is Analysis Countable or Uncountable?

The word analysis can be countable when it refers to a particular study or examination. You can have one analysis, two analyses, or several analyses.

Examples:

• We need an analysis of the problem.
• The team completed two analyses.
• Each analysis examines a different question.

The word can also describe the general process of examining information.

For example, “Analysis is important in scientific research” refers to the activity as a whole, rather than one specific study.

In this general sense, analysis behaves like an uncountable noun. You would not normally say “an analysis is important in scientific research” if you mean analysis as a broad activity rather than a particular examination.

Context matters. The same word can be used differently depending on If you mean a specific piece of work or a general process.

If you want to refer to several specific pieces of work, analyses is usually the right choice.

FAQs About Analyses or Analysis

1. Is analyses the plural of analysis?

Yes. Analyses is the standard plural form of analysis. Use analysis for one examination and analyses for two or more examinations.

2. Is analysis or analyses correct in American English?

Both are correct in American English. The correct choice depends on the number of examinations you mean, not on regional spelling rules.

The correct spelling is analyses. Do not write analysises. The ending changes from -sis to -ses.

4. Should I write “the analysis is” or “the analysis are”?

Write “the analysis is” when referring to one examination. Analysis is singular, so it normally takes a singular verb.

5. Should I write “the analyses is” or “the analyses are”?

Write “the analyses are.” Analyses is plural, so it normally takes a plural verb when it is the subject of the sentence.

In standard American English, analyses is pronounced approximately “uh-NAL-uh-seez.” Analysis ends with a sound like “sis,” while analyses ends with a sound like “seez.”

Conclusion: Analyses or Analysis

Choosing between analyses or analysis is easy once you understand the difference. Analysis is the singular form, used when you mean one study, review, or examination. Analyses is the plural form, used when you mean two or more studies or examinations. Both words are correct in American English, so the important thing is to match the word to your intended meaning.

Remember the simple examples: “The analysis is complete” and “The analyses are complete.” Also, avoid spelling mistakes such as analysises and check that your verbs agree with the noun.

If you are unsure, count the examinations you are describing. One means analysis; more than one means analyses. Practice this rule in your emails, schoolwork, and blog articles, and you will soon use both words with confidence.
