You are halfway through a report when your spell checker draws a red line under a word you were sure was fine. Analysing or analyzing? Both are correct. Analyzing is the American spelling, and analysing is the British spelling. Pick the one that matches your audience, stay consistent, and nobody will ever flag it. Let’s break it down so you never second guess it again.
Analysing
Analysing is the British English spelling of the verb form that means examining something closely to understand it. It is the present participle of “analyse,” the same way “walking” comes from “walk.”
You will see it in the United Kingdom, Australia, New Zealand, Ireland, India, and Pakistan. If your reader learned English with a British style textbook, this is the spelling they know.
Here is a quick example: “The team is analysing last quarter’s sales figures.”
Analyzing
Analyzing is the American English spelling of the exact same word. Same meaning, same pronunciation, one different letter.
The United States and Canada use it as the standard. Most American style guides, including the ones newsrooms and universities follow, treat the “z” version as the only correct choice.
Example: “The coach is analyzing game footage before Friday’s match.”
So far, the only difference is s versus z. Now let’s pin down what the word actually means.
Analysing or Analyzing Meaning

Both spellings mean the same thing: breaking something into parts so you can understand how it works. You can analyze a poem, a spreadsheet, a blood sample, or your friend’s suspicious text message.
The word covers three common ideas:
- Examining details to find patterns, such as analyzing website traffic
- Interpreting meaning, such as analyzing a speech
- Testing and measuring, such as analyzing soil in a lab
Notice that the meaning never changes between countries. Only the spelling does. That makes this one of the easiest transatlantic differences to fix.

Analysing English
Where does this word sit in the bigger English picture? “Analyse” is a regular verb, so it follows regular rules:
- Base form: analyse / analyze
- Third person: analyses / analyzes
- Past tense: analysed / analyzed
- Present participle: analysing / analyzing
One small trap shows up here. The noun “analyses” (the plural of “analysis”) looks identical to the verb “analyses” in British English. Context tells you which one it is. In American English, the verb becomes “analyzes,” which quietly solves that confusion.
Analysing or Analyzing: Quick Answer
Here is the short version you can screenshot:
- Writing for a US or Canadian audience? Use analyzing.
- Writing for a UK, Australian, Irish, Indian, or Pakistani audience? Use analysing.
- Writing for a global audience? Choose one and use it every time.
That is the whole rule. Everything below simply gives you more confidence and a few tricks to avoid mistakes.
Examples
Seeing both spellings in real sentences makes the pattern stick. Here are British examples first:
- “She spent the weekend analysing customer feedback.”
- “The doctor is analysing the test results this afternoon.”
- “We are analysing why the bus arrives late every single Monday.”
That last one deserves a gold medal in British optimism.
Analyzing Examples
Now the American versions:
- “He is analyzing the data before the board meeting.”
- “The detective kept analyzing the footprints near the window.”
- “I am analyzing my budget, and my coffee habit is the main suspect.”
Spot the pattern? Swap the “s” for a “z” and you move from one country to the other.
The Origin of Analysing or Analyzing

Why do two spellings exist at all? The story starts in ancient Greece. The word comes from the Greek analysis, which means “a loosening up” or “a breaking apart.” The root lysis means “to loosen.”
The word traveled into French as analyser, then into English around the 1600s. Early English writers used it with an “s” because that matched the French style.
Then came Noah Webster, the American dictionary writer. In the early 1800s he pushed to simplify English spelling and make it match pronunciation. He favored “z” spellings in many words, and American publishers followed.
Here is the twist most articles skip. The “ize” ending in words like “organize” comes from the Greek suffix izein. But analyse has no such suffix. Its “yze” or “yse” ending comes from lysis. That means Americans took a word that never had an “ize” origin and gave it a “z” anyway. It is a cousin of “paralyse” and “catalyse,” which follow the same split.
That history sets up the broader spelling divide.
British English vs American English Spelling
British and American English differ in predictable ways. Once you know the patterns, you can guess spellings with surprising accuracy.
Common differences include:
- s vs z: analyse / analyze, paralyse / paralyze
- our vs or: colour / color, behaviour / behavior
- re vs er: centre / center, theatre / theater
- double l: travelling / traveling, cancelled / canceled
The “analyse” pair belongs to the first group. Which brings us to a rule worth remembering.
Key Rule:
If a verb ends in “yse” in British English, it ends in “yze” in American English. That covers analyse, paralyse, and catalyse. There are no exceptions to worry about for everyday writing.
A quick wrinkle: Oxford University Press uses “ize” in many words (organize, recognize) but still writes “analyse.” So even within British English, the “z” shows up elsewhere. Do not let that confuse you. For this particular word, British writers use “s.”
Analysing or Analyzing in English
Is one spelling more “English” than the other? No. Neither is a mistake, and neither is outdated.
English has no single governing body that picks a winner. Dictionaries record how people write. The Oxford English Dictionary lists both. Merriam Webster lists “analyze” first, and Cambridge lists “analyse” first for its British audience.
Think of them as two uniforms for the same player. The player is the same. The kit changes depending on which stadium you walk into.

Which Spelling Should You Use?

Ask yourself one question: who is reading this?
- A US based company? Go with analyzing.
- A UK university essay? Go with analysing.
- A Pakistani or Indian business email? Analysing is the safer pick, because local schools and offices follow British style.
- A Canadian audience? Analyzing, since Canadian English follows American spelling for this word.
- A global blog? Choose either one, then match your other spellings to it.
Matching matters more than choosing. A piece that says “analyzing” in one paragraph and “colour” in the next looks careless.
Simple Rule:
Match your audience, then stay consistent from the first word to the last.
Analysing or Analyzing Examples
Let’s put both spellings in everyday sentences so you can see how natural each one feels:
British style:
- “We are analysing the survey before Thursday.”
- “The students were analysing a short story.”
American style:
- “We are analyzing the survey before Thursday.”
- “The students were analyzing a short story.”
The sentence structure never changes. You are simply choosing a spelling dialect. That makes this an easy fix once you know your audience.
Common Mistakes with Analysing or Analyzing
Even careful writers slip here. Watch for these traps:
- Mixing spellings in one document. You write “analyzing” in the intro and “analysed” in the conclusion. Pick one dialect.
- Spelling it “analysing” with a “z” in the middle, or “analyzeing.” Drop the final “e” before adding “ing.”
- Confusing it with “analysis.” Analysis is a noun. Analyzing is an action. You perform an analysis by analyzing.
- Trusting autocorrect blindly. Your device language setting might be US English while your client is in London. Check it before sending.
- Writing “analyzation.” This word is not standard. Use “analysis” instead.
Fix these five and you are ahead of most writers online. Now let’s see how it plays out in real situations.
Analysing or Analyzing in Everyday Examples
Spelling rules feel abstract until you see them in action. Here is how each spelling shows up in common writing situations.
1. Emails
Match the recipient. Writing to a manager in Manchester? “I am analysing the latest numbers and will reply by noon.” Writing to a client in Chicago? “I am analyzing the latest numbers and will reply by noon.”
2. News Writing
News outlets follow house style. The BBC and The Guardian use “analysing.” The New York Times and The Washington Post use “analyzing.” Newsrooms are strict about this, so check the style guide before filing a story.
3. Social Media
Social posts are casual, so either spelling passes. Still, match your audience. A tweet reading “Analyzing my sleep data and I am deeply concerned” works for a US follower base. A British follower base would expect “analysing.”
4. Academic Writing
Universities usually set a spelling standard in their guidelines. UK, Australian, and Pakistani universities expect “analysing.” US universities expect “analyzing.” When in doubt, read the assignment brief, then match it exactly.
5. Business Reports
Corporate documents should follow the company’s regional standard. A multinational firm often publishes a style guide stating US or UK English. If yours does not, ask. A quick question beats a reprinted report.
Analysing or Analyzing Grammar
Grammar is the same for both spellings, so one set of rules covers everything.
Analysing / analyzing is a present participle. It works in three ways:
- Continuous tense: “She is analyzing the results.”
- Gerund (noun use): “Analyzing takes patience.”
- Adjective use: “An analyzing mind notices details.”
It also pairs naturally with prepositions. You analyze data, analyze for patterns, and analyze by category.
One grammar note: the word is usually transitive, meaning it needs an object. “She is analyzing” feels unfinished. “She is analyzing the contract” feels complete.
Is Analysing a Word
Yes, analysing is a real word. It is not a typo, and it is not slang. Every major British dictionary includes it, and the Oxford English Dictionary lists it as an accepted spelling.
Some American spell checkers flag it with a red underline. That does not mean it is wrong. It means the software defaults to US English. Change the language setting to English (UK) and the red line disappears.
Analysing or Analyzing: Google Trends and Usage Data

Search interest and book usage data tell a clear story. The “z” spelling dominates globally because the United States has the largest English speaking online audience. The “s” spelling leads in the UK, Australia, and much of South Asia.
Search data also shows a steady curiosity about this exact question. People type “analysing or analyzing” because spell checkers disagree with them, which is the exact moment this article is built for.
Usage Insight:
Writers searching this question are often mid task. They want a fast answer, then they want to get back to work. That is why clarity beats length on this topic. For exact figures, check Google Trends and the Google Books Ngram Viewer yourself, since the numbers shift over time.
Analysing or Analyzing Synonyms
Sometimes the best fix is avoiding the spelling debate completely. Use a synonym:
- Examining
- Studying
- Reviewing
- Assessing
- Evaluating
- Inspecting
- Breaking down
- Investigating
Each one carries a slightly different feel. “Examining” suggests close inspection, “reviewing” suggests a second look, and “evaluating” suggests judging quality. Pick the one that fits your sentence best.
This is also a neat trick for global audiences. If you are unsure which dialect to use, a synonym sidesteps the problem.
