You’re polishing a report when your spell-checker flags a word. Now you’re stuck on Analysing or Analyzing and wondering which one to keep. Here’s the short answer. Both are correct. Analysing is the British spelling and analyzing is the American spelling. The meaning stays the same. So does the pronunciation. Your reader’s location decides which one looks right.
Why do two spellings exist at all? It comes down to history, dictionaries, and a few style guides. You’ll learn which version fits the United Kingdom, the United States, and Australia. You’ll also see real examples, common slip-ups, and quick ways to choose. Spelling feels small until a client circles it in red. A wrong guess won’t ruin your message but it can look careless.
Analysing or Analyzing: Which Spelling Is Correct?
Both spellings are correct.
Analysing grows from the verb analyse and analyzing grows from the verb analyze.
The split is regional and has nothing to do with grammar.
British/Commonwealth English uses the spelling with S while American English uses the spelling with Z.
Think of a power plug. The electricity is the same but the socket shape depends on the country.
Your readers work the same way. Match their socket and nothing sparks.
Analysing vs. Analyzing: Meaning and Difference
Both words mean examining something closely to understand how it works.
There’s no difference in meaning, tone, or pronunciation. Both sound like AN-uh-lye-zing.
Both come from the Greek word analusis, which means a loosening or breaking up.
English picked it up through Latin and French and ended up with two endings.
The grammar works the same too. Analyse or analyze is the verb base.
Analysing or analyzing is the present participle. Analysis is the noun form.
| Form | British / Commonwealth | American |
| Verb base | analyse | analyze |
| Present participle | analysing | analyzing |
| Past tense | analysed | analysed → analyzed |
| Noun form | analysis | analysis |
| Person | analyst | analyst |
Notice that the noun never changes.
Analysis is always the correct noun form. Analyzis is incorrect everywhere.
British English vs. American English Spelling
Most regional spelling differences trace back to a few English spelling conventions.
British writers often use -ise/-yse endings while Americans stick to -ize/-yze endings.
Analyse and analyze follow that pattern perfectly.
Here’s how each region handles them.
Analysing in British English
In the United Kingdom, analysing is the standard spelling.
You’ll also write analyzes and analyzes. The noun stays analysis.
Newspapers follow this habit. The Guardian style guide uses -ise endings.
The Cambridge Dictionary labels analyse as the UK form.
British academic publishing follows suit.
A UK journal will usually flag analyzing as an American spelling.
Analyzing in American English
In the United States, analyzing is standard along with analyzed and analyze.
You’ll see this American spelling in Merriam-Webster.
APA style, Chicago style, and AP Style all follow American spelling.
So American academic journals expect the Z.
Canada leans this way too.
Canadian English uses analysis even though it keeps British spellings like colour.
Analysing or Analyzing in Australian English
Australian English follows British conventions here.
So analysing with an S is the norm in Australia.
New Zealand and South Africa do the same.
India usually follows suit because Indian English grew from British roots.
This quick list shows where each spelling lives.
- Spelling with S (analyse, analysing): United Kingdom, Australia, New Zealand, South Africa, India
- Spelling with Z (analyze, analyzing): United States, Canada
Local newsrooms in each country stick to these habits.
Follow them when you write for those readers.
Oxford English Spelling: Analyse or Analyze?
Here’s a twist. Oxford English spelling loves the -ize ending in words like organize and realize.
Yet it still writes analyse.
The reason is the root. Words like analyse come from Greek nouns ending in lysis.
So the ending isn’t the usual -ize suffix, and Oxford keeps paralyse and catalyse too.
A writer following Oxford style should still choose analysing.
The Z version looks American to UK editors.
A Short History: Noah Webster and the Z
The split didn’t happen by accident.
In the late 1700s and early 1800s, Noah Webster wanted American spelling to look simpler.
Webster’s 1828 dictionary, titled An American Dictionary of the English Language, backed shorter forms like color and center.
These Noah Webster spelling reforms nudged American publishers toward the Z.
Meanwhile British printers kept their own habits.
By the 19th century the spelling differences had hardened into two camps. No one ever passed a formal English spelling reform, so both camps still stand.

Choosing the Right Spelling for Academic and Professional Writing
Academic writing follows the journal or school.
American academic journals expect the Z while British academic publishing expects the S.

Emails, news writing, and social media writing follow the outlet or audience.

Maintaining Consistency in Your Writing
Spelling consistency matters more than the spelling you pick.
Choose one spelling and stay consistent from the first line to the last. Do not mix spellings in one document.
Picture a freelancer who writes analysed in paragraph two and analyzing in paragraph nine.
The client notices and starts doubting the facts too.
These four steps keep your spelling steady.
- Set your spell-checker to English (United States), English (United Kingdom), or English (Australia) before you write.

- Run find and replace to catch the other spelling before you publish.

They can’t guess your audience.
