Quick Answer
Apologise is the British English spelling, while apologize is the American English spelling. Both mean to express regret or say sorry. British English also accepts apologize, so the difference is mainly a matter of regional spelling preference. Choose the spelling that matches your audience and use it consistently.
Why Do People Confuse Apologise and Apologize?
People confuse these words because only one letter changes: s in apologise and z in apologize. Both forms have the same meaning, pronunciation, and grammatical function.
The confusion also comes from differences between British and American spelling conventions. British English often uses -ise endings, whereas American English generally prefers -ize for words such as organize, realize, and recognize.
However, British English can also use -ize spellings. Therefore, it is not always accurate to say that every British word must end in -ise.

Common Mistakes to Avoid
Although apologise and apologize are both correct, learners sometimes make mistakes when using them.
Mistake 1: Thinking One Spelling Is Always Wrong
Incorrect assumption: “Apologise is wrong because American English uses apologize.”
Correction: Both spellings are correct. Apologise is common in British English, while apologize is standard in American English.
Mistake 2: Mixing British and American Spellings
Inconsistent writing:
- The company apologised for the delay.
- It later apologized for the inconvenience.
Better approach: Choose one spelling style and use it consistently.
Mistake 3: Using the Wrong Verb Form
Incorrect: She apologize for her mistake yesterday.
Correct: She apologized for her mistake yesterday.
The past tense is apologised or apologized, depending on the spelling convention.
Mistake 4: Forgetting the Correct Preposition
Incorrect: I apologise you for my mistake.
Correct: I apologise to you for my mistake.
Use apologise/apologize to someone for something.
Examples:
- He apologized to his mother for his behavior.
- She apologised to the customer for the delay.
Mistake 5: Confusing Apologise With Apology
Apologise is a verb, while apology is a noun.
- Verb: I apologize for the error.
- Noun: Please accept my apology.
Both are useful, but they perform different grammatical functions.
Memory Trick: How to Remember the Difference
Use this simple trick:
S for British spelling, Z for American spelling.
- Apologise → British English
- Apologize → American English
Think of the s in apologise as a reminder of the spelling used in many British English style guides. Think of the z in apologize as the spelling preferred in American English.
Remember that British English also permits -ize spellings in some established styles, so this is a useful guide rather than an absolute rule.
American vs British English: What Is the Difference?
The main difference between apologise and apologize is spelling preference.
American English generally uses -ize, while British English commonly uses -ise in words such as apologise, organise, and recognise. Some British dictionaries and style guides also accept -ize spellings.
Here are a few related examples:
| British English | American English |
|---|---|
| Apologise | Apologize |
| Organise | Organize |
| Recognise | Recognize |
| Realise | Realize |
| Apologised | Apologized |
| Apologising | Apologizing |
There are other regional differences beyond spelling. For example, British English commonly uses behaviour, while American English uses behavior.
