Snippet Answer: “Analysis” is singular, meaning one detailed examination, while “analyses” is the plural form used for multiple examinations.
During a team meeting, a marketing manager asked a simple question: “Have you completed the data analyses?” One team member replied, “Yes, the analysis is ready.” The room went quiet for a moment. Were they talking about the same thing?
This small difference between analysis and analyses often confuses writers, students, and professionals. At first glance, both words look almost identical. The only visible change is in the ending. Yet that small change completely shifts the meaning of the sentence.
People frequently search online for “analyses or analysis” because they want to know which word is correct in their writing. Is one singular? Is the other plural? And why does the spelling change so dramatically?
The confusion becomes even stronger in academic, scientific, and business writing where these words appear regularly. From research papers to business reports, using the correct form is important for clarity and professionalism.
In this guide, you will learn the clear difference between analysis vs analyses, their origins, how to use them correctly, and how to avoid common mistakes.
Analyses or Analysis – Quick Answer
The difference is simple once you know the rule.
- Analysis = Singular (one examination or study)
- Analyses = Plural (more than one examination or study)
Examples:
✔ The scientist completed a detailed analysis of the experiment.
✔ The researchers published several analyses of climate data.
Think of it like this:
- One study → analysis
- Many studies → analyses
This plural pattern is common in words that end in -sis.
The Origin of Analysis and Analyses
The word analysis comes from the Greek word “analusis,” which means to break something apart for examination. It combines two Greek parts:
- ana – meaning up or apart
- lysis – meaning loosening or separating
Together, the word describes the act of breaking something down to understand it better.
Because the word entered English through Greek and Latin influences, it kept its unusual plural form. Instead of adding -s like most English nouns, it changes from analysis → analyses.
This pattern appears in several other English words that share Greek roots.
Examples:
| Singular | Plural |
| analysis | analyses |
| crisis | crises |
| thesis | theses |
| basis | bases |
| diagnosis | diagnoses |
These irregular plural forms are the main reason people become confused when writing.
British English vs American English Spelling
Unlike many English words, analysis and analyses are spelled the same in both British and American English.
There is no spelling difference between the two dialects.
Examples:
- US English: The financial analysis shows strong growth.
- UK English: The financial analysis shows strong growth.
Both regions also use the same plural form analyses.
Comparison Table
| Feature | Analysis | Analyses |
| Meaning | One examination | Multiple examinations |
| Word type | Singular noun | Plural noun |
| Used in US English | ✔ Yes | ✔ Yes |
| Used in UK English | ✔ Yes | ✔ Yes |
| Common in academic writing | ✔ Very common | ✔ Very common |
So the difference is not regional spelling. It is purely singular vs plural grammar.
Which Spelling Should You Use?
Choosing the correct form depends entirely on how many studies or examinations you are referring to.
Use analysis when referring to one study
Example:
The company released a market analysis of smartphone trends.
Use analyses when referring to multiple studies
Example:
The report includes several analyses of customer behavior.
Quick rule
- One → analysis
- More than one → analyses
This rule applies across academic writing, journalism, business reports, and everyday communication.
Common Mistakes with Analysis and Analyses
Even experienced writers sometimes misuse these words. Here are the most common errors.
1. Using analysis as a plural
❌ The report includes several analysis.
✔ The report includes several analyses.
2. Using analyses for a single study
❌ The analysis were completed yesterday.
✔ The analysis was completed yesterday.
3. Confusing pronunciation
Many learners mispronounce the words because they look similar.
Correct pronunciation:
- analysis → uh-NAL-uh-sis
- analyses → uh-NAL-uh-seez
4. Mixing singular and plural verbs
❌ The analyses shows clear results.
✔ The analyses show clear results.
Grammar agreement is important when using plural nouns.

Analysis vs Analyses – Google Trends & Usage Data
Search data shows interesting patterns.
The keyword analysis receives far more searches than analyses. This is because people often talk about a single report or examination.
However, analyses appears frequently in academic research, scientific papers, and technical reports.
Countries with the highest search interest include:
- United States
- United Kingdom
- Canada
- India
- Australia
Students, researchers, and business analysts commonly search for the difference because grammar rules for -sis plural forms are not intuitive.
Keyword Comparison Table
| Keyword Variation | Meaning | Search Popularity |
| analysis | singular form | Very high |
| analyses | plural form | Medium |
| data analysis | examining data | High |
| market analysis | business evaluation | High |
This shows that while both words are important, analysis is used more frequently in everyday searches.

Conclusion
The difference between analysis and analyses is simple once you understand the grammar rule. The word analysis refers to a single examination or detailed study of something. On the other hand, analyses is the plural form used when discussing multiple studies or evaluations.
This distinction is important in many fields, including academic research, business reports, journalism, and data science. Because the word comes from Greek roots, its plural form does not follow the typical English pattern of simply adding “-s.” Instead, it changes from analysis to analyses, just like other words such as crisis to crises or thesis to theses.
If you remember one easy rule, you will never get confused again: one study equals analysis, and multiple studies equal analyses. Using the correct form helps your writing sound clear, accurate, and professional in both everyday communication and formal documents.
