Quick Answer
The fastest way to know which spelling to use.
The difference between apologize and apologise comes down entirely to geography.
If you are writing for an audience in the United States, the correct spelling is apologize with a 'z'. If you are writing for an audience in the United Kingdom, Australia, or New Zealand, the correct spelling is apologise with an 's'.
Both words refer to the exact same action: expressing regret or remorse for a mistake or offense. Neither spelling is grammatically incorrect, but using the wrong one for your target region can look out of place in professional writing.

American English: Apologize
How the word is used in the United States.
In the United States, "apologize" is the universally accepted spelling. It is used by the Associated Press (AP), major American newspapers, universities, and everyday speakers. The spelling uses the 'z' to match the word's Greek origins, adhering to standard American English conventions for '-ize' verbs.
Industry Standard
American publishing houses and corporate communication guidelines exclusively use "apologize" in their style manuals.
Media and Publishing
Major publications like The New York Times and The Washington Post strictly follow the "apologize" spelling with a 'z'.
British English: Apologise
How the word is used in the United Kingdom.
In the United Kingdom, "apologise" is the traditional and standard spelling. It uses the 's' in line with the standard British English preference for '-ise' verb endings. While "apologize" is also understood and historically used in UK English (notably by Oxford University Press), "apologise" is the dominant everyday spelling.
Cultural Presence
The spelling is standard in British correspondence, from corporate emails to published literature.
Modern Usage
Though Britons might just say "sorry" in casual speech, formal British writing relies on "apologise" rather than the American 'z' adaptation.
What Do Both Words Mean?
The definition remains exactly the same.
Despite the spelling difference, both "apologize" and "apologise" mean exactly the same thing. They refer to the act of expressing regret, remorse, or acknowledging a fault or offense.
Core Definition
To offer an apology or express regret for a mistake, injury, or insult.
Not an Admission of Liability
In legal and professional contexts, apologizing/apologising is often framed as expressing sympathy without necessarily admitting legal liability.
American English Usage
How Americans naturally use the word today.
In the US, "apologize" is used in almost every context, from casual conversation to technical corporate statements. It is the standard form for all '-ize' verbs in American English.
Casual Conversation
"I need to apologize for being late to the meeting." (Though most Americans just say "I'm sorry").
Corporate Writing
"The CEO apologized for the service outage in a public statement."
Customer Service

Literature and Media

Everyday Conversation

Public Relations

News and Journalism

Which Spelling Should You Use?
Deciding based on your audience.
The decision is entirely context-driven. If you are writing an email to an American colleague, use "apologize." If you are writing a formal letter to a British institution, use "apologise."
Choose "Apologize" if:
You are writing for a US-based publisher, studying at an American school, or creating content primarily for an American audience.
Choose "Apologise" if:
You are submitting to a UK journal, writing for a British audience, or following Commonwealth English standards.
Formal and Professional Writing
What to do in business and academic contexts.
In highly formal writing, the safest approach is to strictly follow the style guide of your target region. Unlike some words where a broader term can be used to avoid the spelling trap, there is no exact alternative verb for apologize/apologise that avoids the split.
Business Contracts
International legal documents often use "express regret" if they want to avoid regional spelling pitfalls, though "apologize/apologise" is common.
Academic Research
Academic papers must adhere to the journal's specific style guide, whether APA (US, 'z') or a UK equivalent ('s').
Pronunciation
The spelling change does not affect how the word is spoken.
Unlike some spelling differences, the 's' vs 'z' does not change the spoken word at all in standard English. Both letters produce a voiced 'z' sound in this context.
| Word | IPA | Syllables |
|---|---|---|
| Airplane (US) | /əˈpɑlədʒaɪz/ | 4 (uh-POL-uh-jize) |
| Aeroplane (UK) | /əˈpɒlədʒaɪz/ | 4 (uh-POL-uh-jize) |
The 's' in the British spelling is not pronounced as an 's' sound (like in 'sun'); it is pronounced as a 'z' sound (like in 'buzz'). Therefore, both American and British speakers pronounce the word exactly the same, with four syllables.
Spelling Difference
A visual breakdown of the letters.
The core difference is the final letter before the 'e', either an 's' or a 'z'.
The American version uses a 'z', adhering to the Greek origins of the '-ize' suffix. The British version uses an 's', reflecting the standard British preference for the '-ise' ending in modern English.
Why Are the Spellings Different?
The history behind the transatlantic split.
1. The Greek Roots
The word comes from the Greek 'apologia', meaning a speech in defense. When it entered English, the verb form took the '-ize' suffix, derived from the Greek '-izein'.
2. Noah Webster's Reform
In the early 1800s, American lexicographer Noah Webster explicitly promoted the '-ize' ending. He believed it was more etymologically correct, aligning with the Greek root, and cemented 'apologize' as the American standard.
3. The British Shift
Despite the Greek origins, British English was heavily influenced by French spelling conventions, which often use '-iser' for verbs. Over the 19th and 20th centuries, '-ise' became the standard everyday spelling in the UK, leading to 'apologise', though Oxford University Press historically retained '-ize' (known as Oxford spelling).

Common Mistakes
Frequent errors writers make with these spellings.
Mixing spellings within the same document.
✓ Pick one regional standard and stick to it.
Why: Writing "He apologized, but she didn't apologised" confuses the reader and breaks the consistency of your text.
Using "apologise" in an American academic paper.
✓ Use "apologize" for US-based journals and schools.
Why: American professors and publishers expect standard American English. Using the British spelling looks like a typo or an oversight in this context.
Spelling the word with an 's' sound in mind (apologice).
✓ Always use 'ze' (US) or 'se' (UK).
Why: Some writers mistakenly use a 'c' to represent the 's' sound, but modern English uses 'se' or 'ze' for the suffix.
Using "apologize" for a British children's book.
✓ Use "apologise" for UK audiences.
Why: British publishers strictly enforce regional spelling standards, especially in educational materials for kids.
Pronouncing "apologise" with a hard 's' sound.
✓ Pronounce both as "uh-POL-uh-jize."
Why: The 's' in the British spelling is not pronounced as an 's' (like in sun); it is voiced as a 'z' (like in buzz), exactly like the American version.
Assuming "apologise" is outdated or archaic.
✓ Recognize it as the current, active British spelling.
Why: Some Americans assume it's an old-fashioned word, but it is entirely modern and standard in the UK today.
Forgetting that the noun form changes too.
✓ Use "apologizer" (US) and "apologiser" (UK) if needed.
Why: The regional spelling split carries over to all derivatives of the word, though the noun 'apology' remains the same in both.
Thinking 'apologize' is wrong in the UK.
✓ Note that Oxford spelling uses 'apologize'.
Why: Oxford University Press and some scientific journals in the UK use the 'z' spelling (Oxford spelling), though 'apologise' is the general standard for the public.
Forgetting that Canada usually aligns with the US on this term.
✓ Use "apologize" for Canadian audiences.
Why: Despite being in the Commonwealth, Canadian English heavily favors American '-ize' spellings for this word.
Confusing the verb with the noun.
✓ Keep "apologize/apologise" distinct from "apology."
Why: "Apologize" is the action (verb), while "apology" is the statement or thing offered (noun). This distinction is identical in both US and UK English.
Writing for an International Audience
How to handle the split when writing globally.
If you are writing a blog, book, or manual for a global audience, you must pick a primary English standard. Most international organizations choose either US or UK English as their default and stick to it.
Pro Tip: Because of the dominance of American media and software, many ESL learners are more familiar with "apologize." However, if your organization is based in Europe or the Commonwealth, "apologise" is the expected standard.
Memory Tip
An easy way to remember which spelling belongs to which country.
If you struggle to remember the difference, use this simple association trick:
Notice the letter 'z'. America has a 'z' in its cultural preference for the letter (think of the 'Z' in Uncle Sam's zealous attitude), while the UK prefers the smooth 's' in apologise.
