Apologise or Apologize – Quick Answer
Apologize is the American spelling. Apologise is the British spelling. Both mean the same thing: to say you are sorry.
- US: “I apologize for the delay.”
- UK: “I apologise for the delay.”
Pick one spelling and use it every time in the same text. Do not mix them.
The Origin of Apologise and Apologize
The word starts with the Greek word apologia. It means “a speech in defense.” It joins apo (away) and logos (speech). In ancient Greece, an apologia was a speech you gave to defend yourself.
The word passed into Latin, then into French. It reached English in the 1500s. At first, people used it to mean defending an idea. Later it came to mean saying sorry.
So why two spellings? The Greek ending -izein became -izare in Latin. English borrowed the -ize ending from that path. French, however, changed the ending to -iser. Some British writers followed the French style and used -ise.
In the 1800s, American writer Noah Webster wanted simple, sound-based spelling. He pushed for -ize in his dictionary. That is why -ize became the standard in the US.
British English vs American English Spelling
The rule is simple. Many verbs end in -ise in British English and -ize in American English. Apologise is one of them.
| Word | American English | British English |
| Apologize | apologize | apologise |
| Past tense | apologized | apologised |
| -ing form | apologizing | apologising |
| Organize | organize | organise |
| Realize | realize | realise |
| Recognize | recognize | recognise |
Some things do not change. The noun apology is the same in both. So are apologist, apologetic, and apologetically. Only the verb forms change.
One more note: some British publishers, such as Oxford University Press, also use -ize. So “apologize” is not wrong in the UK. It is just less common.
Which Spelling Should You Use?
Think about your reader.
- Writing for the US: Use apologize.
- Writing for the UK, Australia, New Zealand, or Ireland: Use apologise.
- Writing for Canada: Use apologize. Canadians mostly prefer -ize.
- Writing for India, Pakistan, or South Africa: Use apologise. These regions follow British style. Check your school or company guide.
- Writing for a global audience: Either works. Choose one and stay consistent. Many global brands pick apologize.
- Working with a style guide: Follow it. Company and school rules come first.
A quick tip: set your spell checker to the right language, such as English (US) or English (UK). It will catch mistakes for you.
