Analyses or Analysis: Meaning, Difference And Usage

You are staring at a sentence, unsure whether to write “the analysis shows” or “the analyses show,” and both look strange the longer you stare at them. This mix up happens because the two words look almost identical but follow a plural pattern most English speakers never learned in school.

Here is the direct answer: “analysis” is the singular form, and “analyses” is the plural form. You use “analysis” when talking about one examination or study, and “analyses” when talking about two or more. Both words are correct, just in different situations, so neither one is a mistake on its own.

What Does “Analysis” Mean

“Analysis” is a noun that refers to a detailed examination of something in order to understand it better. It can describe a written report, a mental process, or a method used in science, business, or everyday reasoning.

For example, a financial analyst might say, “My analysis shows the company is undervalued.” Here, “analysis” refers to one single piece of work, one report, one conclusion.

What Does “Analyses” Mean

“Analyses” is simply the plural of “analysis.” It refers to more than one examination, report, or breakdown. If a researcher completed three separate studies, they would say, “My analyses all point to the same conclusion.”

“Analyses” can also function as a verb in British English, but that use is spelled and pronounced differently, which we will cover shortly.

The Real Difference Between Analysis And Analyses

The core difference is simply number. “Analysis” is singular. “Analyses” is plural. Neither word is more correct than the other; they simply serve different grammatical roles depending on how many things you are describing.

Term	Correct?	Meaning	Use
Analysis	Yes	One examination or study	“The analysis was thorough.”
Analyses	Yes	Two or more examinations or studies	“The analyses were thorough.”
Analyzes (US verb)	Yes	Third person verb, present tense	“She analyzes the data daily.”
Analyses (UK verb)	Yes, in British English	Third person verb, present tense	“She analyses the data daily.”

Why This Word Confuses So Many People

Most English nouns become plural by adding an “s” at the end, like “book” becoming “books.” But “analysis” belongs to a small group of words borrowed from Greek that follow a different pattern. Instead of adding a letter, the ending itself changes from “-is” to “-es.”

This same pattern shows up in other Greek derived words like “crisis” and “crises,” “thesis” and “theses,” and “basis” and “bases.” Once you notice the pattern, the plural form of “analysis” becomes much easier to remember.

Grammar Breakdown: Part Of Speech And Forms

Both “analysis” and “analyses” are nouns. Neither one is an adjective, adverb, or standalone verb in American English. Here is a quick breakdown of how the word behaves grammatically.

Singular noun: analysis
Plural noun: analyses
Adjective form: analytical (as in “analytical thinking”)
Adverb form: analytically (as in “she reviewed the report analytically”)
US verb form: analyze, analyzes, analyzed, analyzing
UK verb form: analyse, analyses, analysed, analysing

Notice that “analyses” appears twice in this list. In American English, “analyses” is always the plural noun. In British English, “analyses” can also be the present tense verb form of “analyse,” which adds another layer to the confusion.

Where Does “Analysis” Come From

“Analysis” comes from the Greek word “analusis,” which means “a breaking up” or “a loosening.” It traveled through Latin before entering English in the late 1500s, originally used in logic and philosophy to describe breaking an idea into smaller parts to understand it.

The Greek origin explains why the plural does not follow the usual English pattern. Many words that entered English directly from Greek kept their original plural structure instead of adopting the standard English “s” ending.

How To Pronounce Analysis And Analyses

Pronunciation is another common source of confusion because the stressed syllable shifts slightly between the two forms.

Analysis is pronounced “uh-NAL-uh-sis,” with the stress on the second syllable.
Analyses is pronounced “uh-NAL-uh-seez,” with the same stress but a different ending sound.

The key difference in speech is the final syllable. “Analysis” ends with a soft “sis” sound, while “analyses” ends with a longer “seez” sound, similar to how “crisis” becomes “crises.”

How To Use “Analysis” Correctly In A Sentence

Use “analysis” whenever you are referring to a single study, report, or breakdown of information.

Everyday conversation: “I gave the situation some analysis before deciding.”
Workplace communication: “Can you send me your analysis of the sales report?”
Academic writing: “This paper presents a detailed analysis of climate data from 2010 to 2020.”
Email: “Attached is my analysis of the proposed budget changes.”

Each of these sentences describes one single piece of analytical work, which is why the singular form fits.

How To Use “Analyses” Correctly In A Sentence

Use “analyses” when referring to two or more studies, reports, or examinations.

Everyday conversation: “I have done several analyses of my monthly spending.”
Workplace communication: “The two analyses came to different conclusions, so we need a third review.”
Academic writing: “The researchers compared their analyses across five different data sets.”
Business writing: “Our quarterly analyses show consistent growth across all regions.”

In each example, more than one analysis exists, so the plural form is required.

Common Mistakes People Make With Analysis And Analyses

Incorrect: “I completed three analysis last week.” Correct: “I completed three analyses last week.” The number “three” signals more than one item, so the plural form “analyses” is required.

Incorrect: “The analyses on my desk needs your approval.” Correct: “The analysis on my desk needs your approval.” Here only one report is being discussed, so the singular form matches the singular verb “needs.”

Incorrect: “She analysises the numbers every Friday.” Correct: “She analyzes the numbers every Friday.” “Analysises” is not a real word. The correct American verb form is “analyzes.”
