Is Analysis Singular or Plural?
The short answer is that analysis is singular. Its plural form is analyses (pronounced uh-NAL-uh-seez). This is a common point of confusion because the word ends in "-sis," which changes to "-ses" in the plural, following a pattern used by other words like "thesis/theses" and "crisis/crises." If you are writing about one detailed examination of data or a topic, use "analysis." If you are writing about two or more such examinations, use "analyses."
Quick Answer: Analysis vs. Analyses
| Form | Number | Example |
|---|---|---|
| Analysis | Singular | The financial analysis shows a clear profit trend. |
| Analyses | Plural | Several analyses were conducted before the merger. |
If you need to check whether you are using the correct form, ask yourself: "Am I talking about one study or more than one?" One = analysis. Two or more = analyses.
Why This Confusion Happens
Many English learners and even native speakers mix up "analysis" and "analyses" because the singular form "analysis" sounds like it could be plural. The word comes from Greek, and it follows a specific pluralization rule: words ending in "-sis" change the ending to "-ses." Other examples include "basis/bases," "hypothesis/hypotheses," and "diagnosis/diagnoses." Once you recognize this pattern, the correct usage becomes much clearer.
Formal and Informal Contexts
In Formal Writing (Reports, Emails, Academic Papers)
In formal business or academic writing, precision matters. You will often see "analysis" used in sentences like "Our analysis of the quarterly data is complete." When multiple studies are involved, you write "The analyses from different departments were compared." Using the wrong form in a report or email can confuse your reader or make your writing seem less careful.
In Informal Conversation or Quick Messages
In everyday conversation or casual emails, people sometimes say "analysis" when they mean multiple analyses, but this is not correct. For example, a colleague might say, "I did some analysis on the numbers," even if they ran several tests. While this is common in spoken English, it is better to use the correct plural form in writing to avoid ambiguity.
Natural Examples
Here are examples that show how "analysis" and "analyses" are used in real business and everyday situations:
- Singular: The market analysis suggests we should launch the product in spring.
- Plural: The team reviewed three separate analyses before making a decision.
- Singular: Her analysis of the customer feedback was thorough.
- Plural: All analyses pointed to the same conclusion: we need to improve delivery times.
- Singular: A cost-benefit analysis is required for every new project.
- Plural: The researchers published their analyses in a peer-reviewed journal.
Common Mistakes
Here are the most frequent errors people make with "analysis" and "analyses," along with corrections:
| Incorrect | Correct | Explanation |
|---|---|---|
| We need to do more analysis on this topic. | We need to do more analyses on this topic. | If you mean multiple studies, use the plural form. |
| The analysis are complete. | The analyses are complete. | The verb "are" requires a plural subject. |
| I have one analysis and two analysis. | I have one analysis and two analyses. | Use "analyses" for two or more. |
| This analyses is important. | This analysis is important. | "Analyses" is plural, so it cannot be used with "this." |
Better Alternatives and When to Use Them
Sometimes, using "analysis" or "analyses" repeatedly can make your writing feel repetitive. Here are some alternatives that work well in different contexts:
- Study (singular) or studies (plural): Good for general use. Example: "The study revealed new insights."
- Review (singular) or reviews (plural): Useful when discussing a thorough examination. Example: "A review of the data was conducted."
- Examination (singular) or examinations (plural): More formal. Example: "The examination of the financial records took two weeks."
- Assessment (singular) or assessments (plural): Common in business. Example: "The risk assessment was updated."
Use these alternatives when you want to vary your language or when the specific word fits the context better. However, "analysis" and "analyses" remain the most precise terms for detailed, methodical examinations.

Frequently Asked Questions
1. Is "analysis" ever used as a plural?
No, "analysis" is always singular. The plural form is always "analyses." Using "analysis" to mean multiple examinations is incorrect in standard English.
2. How do I pronounce "analyses"?
"Analyses" is pronounced uh-NAL-uh-seez. The ending sounds like "sees," not "sis." This is different from the singular "analysis," which ends with a "sis" sound.
3. Can I use "analysis" in a sentence with a plural verb?
No. Because "analysis" is singular, it must be paired with singular verbs like "is," "was," or "shows." For example, "The analysis is complete," not "The analysis are complete."
4. What other words follow the same pattern as "analysis/analyses"?
Many Greek-derived words ending in "-sis" follow this pattern. Common examples include "thesis/theses," "crisis/crises," "hypothesis/hypotheses," "diagnosis/diagnoses," and "basis/bases." Learning this pattern will help you avoid mistakes with all of them.
Final Tips for Using Analysis and Analyses
To remember the difference, think of the word "thesis." One thesis, two theses. One analysis, two analyses. The change from "-sis" to "-ses" is consistent. When you write an email or report, take a moment to check whether you are referring to one examination or multiple. This small habit will make your writing clearer and more professional. If you are ever unsure, replace the word with "study" or "studies" to see which one fits. For example, if "studies" works, use "analyses." If "study" works, use "analysis."
