What Does Analysis Mean?
Analysis is a singular noun that means a careful examination of something by breaking it into smaller parts. The purpose of an analysis is to understand information, discover patterns, solve problems, or make better decisions.
When you perform an analysis, you look beyond the surface. You study details, compare information, and create a clear understanding of a topic.
For example, a teacher may ask a student to write an analysis of a book. The student does not simply explain what happened in the story. Instead, the student examines the characters, themes, writing style, and deeper meaning.
In business, companies use analysis to understand customers, competitors, and financial performance. A company may complete a market analysis before introducing a new product.
Examples of Analysis in Different Fields
Academic writing
- A student writes an analysis of a poem.
- A researcher creates an analysis of previous studies.
- A professor provides an analysis of a historical event.
Business and finance - A company performs a financial analysis before investing money.
- A marketing team prepares a customer analysis to understand buying habits.
- A manager reviews a performance analysis to improve workplace results.
Science and healthcare - A scientist conducts an analysis of laboratory results.
- A doctor reviews a medical analysis before making decisions.
- A researcher completes a statistical analysis of collected data.
Sentence Examples Using Analysis
- The financial analysis showed that the company needed better budgeting.
- Her analysis of the novel revealed hidden themes.
- The team completed an analysis of customer feedback.
- The report includes a detailed analysis of market trends.
In every example above, analysis refers to only one examination.
What Does Analyses Mean?
Analyses is the plural form of analysis. It refers to two or more separate examinations, studies, or evaluations.
Unlike regular nouns that simply add “-s” or “-es,” the word analysis follows an irregular plural pattern. This happens because the word comes from Greek and keeps a similar plural structure.
Here are some similar examples:
| Singular | Plural |
| Analysis | Analyses |
| Diagnosis | Diagnoses |
| Thesis | Theses |
| Crisis | Crises |
| When you talk about multiple studies, investigations, or evaluations, you should use analyses. |
Examples of Analyses in Real Situations
Imagine a company wants to launch a new product. Before making a decision, the company may perform different evaluations:
- Market analyses
- Customer behavior analyses
- Competitor analyses
- Financial analyses
Each evaluation focuses on a different area. Together, they are called analyses.
Sentence Examples Using Analyses
- The researchers compared several analyses before publishing their results.
- The report contains multiple analyses of economic changes.
- Different analyses provided useful information about customer behavior.
- The scientists performed several analyses on the samples.
In these examples, analyses means more than one examination.
Analysis vs Analyses: The Main Difference Explained
The difference between analysis and analyses is based on quantity.
| Word | Meaning | Number | Example |
| Analysis | A detailed examination | One | The analysis was accurate. |
| Analyses | Multiple detailed examinations | More than one | The analyses were accurate. |
| A simple memory rule: |
Analysis = one- Analyses = two or more
Think about it like this:
A detective investigating one case performs an analysis.
A detective comparing several cases performs multiple analyses.
The action is similar, but the number determines the correct word.
Analysis vs Analyses Pronunciation Difference
Many people understand the spelling difference but still struggle with pronunciation.
How to Pronounce Analysis
The pronunciation of analysis is:
uh-NAL-uh-sis
The ending sounds like “sis.”
Example:
- The analysis was completed yesterday.
How to Pronounce Analyses
The pronunciation of analyses is:
uh-NAL-uh-seez
The ending sounds like “seez.”
Example:
- The analyses showed different results.
Why Pronunciation Matters
Correct pronunciation helps people understand your meaning during conversations.
Compare these examples:
- “The analysis is complete.”
- “The analyses are complete.”
The first sentence discusses one completed evaluation. The second discusses several completed evaluations.
A small sound difference can completely change the meaning.
Grammar Rules Behind Analysis and Analyses
Understanding grammar makes this word pair much easier.
A singular noun describes one person, place, thing, or idea.
Examples:
- One report
- One study
- One analysis
A plural noun describes more than one.
Examples: - Several reports

- Several analyses
The word analysis does not become “analysises” because English has irregular plural rules.

Analysis + es = Analysises
However, this pattern is wrong.
The correct forms are:
- ❌ Analysises
- ✅ Analyses
The same rule applies to: - ❌ Diagnosises
- ✅ Diagnoses
- ❌ Thesises
- ✅ Theses
