Plural of Analysis The English language is full of words that don’t follow the usual grammar rules, and one of the most commonly misunderstood examples is the word analysis. Whether you’re writing an academic paper, a business report, or simply improving your grammar, knowing the correct plural of analysis can help you communicate more accurately and professionally.

Many people mistakenly write analysises or assume analysis is both singular and plural. In reality, English borrowed this word from Greek, and it follows a unique pluralization pattern. Once you understand the rule, you’ll find it much easier to use the word confidently in everyday writing.

In this guide, we’ll explain the plural of analysis, why it changes differently from regular nouns, how to use it correctly in sentences, common mistakes to avoid, and several practical examples to help you remember the rule. Plural of Analysis

What Is the Plural of Analysis?

Plural of Analysis The correct plural of analysis is analyses.

Although it may look unusual at first glance, analyses is the standard plural form accepted by dictionaries, universities, publishers, and professional writers. The singular form is analysis, while the plural changes the ending from -is to -es.

For example:

• One analysis
• Two analyses
• Several analyses
• Multiple analyses

This change follows a grammatical pattern shared by several English words that originated from Ancient Greek. Instead of simply adding an “s,” the ending changes entirely, making the word appear different while preserving its pronunciation pattern. Plural of Analysis

Why Does Analysis Become Analyses?

The reason lies in the word’s historical origin.

The word analysis comes from the Greek word analusis. Many English nouns borrowed from Greek ending in -is form their plurals by replacing -is with -es instead of adding a simple “s.”

This rule may seem confusing because most English nouns become plural by adding -s or -es. However, English contains numerous exceptions that preserve their original Greek or Latin endings.

Although modern English has simplified many grammar rules over time, words like analysis have retained their traditional plural forms because they are widely used in science, education, medicine, and professional writing. Plural of Analysis

Examples of Analysis and Analyses in Sentences

Understanding the difference becomes much easier when you see real examples.

When referring to a single examination or study, use analysis.

Examples:

• The researcher completed a detailed analysis of the survey results.
• My analysis shows that customer satisfaction has improved.
• Her analysis of the novel impressed the professor.

When referring to more than one examination or study, use analyses.

Examples:

• The scientists compared several analyses before publishing their findings.
• Different analyses produced similar conclusions.
• The company reviewed multiple financial analyses before making a decision.

Notice that the surrounding verbs also change depending on whether the noun is singular or plural.

Correct:

• The analysis is complete.
• The analyses are complete.

Common Grammar Mistakes People Make

One of the most frequent mistakes is writing analysises. Plural of Analysis

Although it seems logical because many English nouns simply add “-es,” this form is grammatically incorrect. Standard English recognizes only analyses as the plural.

Another common error is using analysis when talking about multiple reports or examinations.

Incorrect:

• We performed several analysis. Plural of Analysis

Correct:

• We performed several analyses.

Some writers also confuse pronunciation with spelling. While the words sound similar, their spellings clearly distinguish singular from plural. Paying attention to context will help you choose the correct form every time.

Other Words That Follow the Same Pattern

The word analysis isn’t alone.

Several English nouns ending in -is change to -es when pluralized.

Examples include:

• Crisis → Crises
• Thesis → Theses
• Basis → Bases
• Diagnosis → Diagnoses
• Hypothesis → Hypotheses
• Parenthesis → Parentheses
• Synopsis → Synopses

Learning these words together makes the grammar rule much easier to remember.

Many of these terms appear frequently in academic writing, medicine, law, engineering, and scientific research, so mastering them can improve both your writing and reading comprehension.

Once you recognize this pattern, you’ll naturally apply it whenever you encounter similar words.

Pronunciation of Analysis and Analyses

Although the spellings differ by only a few letters, the pronunciation changes slightly.

Analysis is generally pronounced:

uh-NAL-uh-sis

Analyses is pronounced:

uh-NAL-uh-seez

The final syllable changes from “sis” to “seez.”

Native English speakers naturally make this pronunciation shift because the plural ending follows the Greek grammatical pattern.

Listening to professional speakers, educators, or news presenters can help reinforce the correct pronunciation if you’re learning English as a second language.

When Should You Use Analysis?

Use analysis whenever you’re discussing a single examination, investigation, evaluation, or detailed study.

This word appears frequently across many industries.

Examples include:

• Market analysis
• Financial analysis
• Literary analysis
• Data analysis
• Risk analysis
• Business analysis
• Scientific analysis

Each phrase refers to one specific study or examination.

Whether you’re writing for school or work, using the singular correctly demonstrates strong grammar skills and professionalism.

When Should You Use Analyses?

Use analyses whenever you’re discussing two or more separate examinations or studies.

Researchers, journalists, professors, consultants, and analysts often compare multiple analyses before reaching conclusions.

For example:

• Several market analyses predicted increased consumer demand.
• Independent analyses supported the same theory.
• Medical analyses confirmed the diagnosis.
• Environmental analyses revealed pollution in the river.
• Financial analyses helped investors evaluate risk.

Using the plural correctly makes your writing clearer and prevents confusion for readers.

Tips for Remembering the Correct Plural

One easy memory trick is to think about other familiar words that follow the same rule.

If you remember:

• Thesis → Theses

then it’s much easier to remember:

• Analysis → Analyses

Another helpful strategy is to focus on the meaning rather than the spelling.

Ask yourself:

“Am I talking about one study or many?”

If it’s one, use analysis.

If it’s more than one, use analyses.

Reading academic articles and professionally edited publications can also reinforce the correct usage because these sources consistently follow standard grammar rules.
