Analysis is singular and refers to one detailed examination of something. Analyses is plural and refers to two or more examinations. If you’re talking about one study, report, or evaluation, use analysis. If you’re talking about multiple studies or evaluations, use analyses.
A few years ago, I was proofreading a business report when I noticed the sentence: “Several market analysis were conducted before the product launch.” Something felt wrong.
The report looked professional. The research was solid. Yet one small word stood out.
The correct phrase should have been “Several market analyses were conducted.”
This is one of the most common mistakes in English writing. Many people know the word analysis, but when they need the plural form, uncertainty creeps in. Some writers incorrectly use analysises, while others use analysis for both singular and plural situations.
If you’ve searched for analysis or analyses, you’re probably wondering which word is correct and when to use each one.
The good news is that the difference is simple once you understand it.
In this guide, you’ll learn the meanings of both words, their origins, real-world examples, common mistakes, and an easy memory trick that will help you remember the difference forever.

The Origin of Analysis or Analyses
Understanding the history makes the spelling easier to remember.
The word analysis comes from Greek.
It originally meant:
- Breaking something apart
- Examining details

Over time, it became a common English word used in science, business, education, medicine, and research.
The plural form follows a Greek language pattern.
Many Greek-derived words change:
| Singular | Plural |
| Analysis | Analyses |
| Crisis | Crises |
| Thesis | Theses |
| Basis | Bases |
Because English rarely follows this pattern elsewhere, many people become confused.
