In this guide, we’ll clarify the difference, explain the history of the word, show how to use it correctly, and give practical examples for both British and American English.

Quick Answer
Simply put:
- Apologise → British English spelling
- Apologize → American English spelling
Examples:
- British English: “I apologise for the delay in my response.”
- American English: “I apologize for the delay in my response.”
Both mean to express regret or say sorry, and both are correct depending on the audience.
The Origin of Apologise/Apologize
The word comes from the Greek word “apologia”, meaning a formal defense or speech in reply. Over centuries, it evolved in English to mean expressing regret or saying sorry.
The spelling difference stems from history:
- -ise endings are traditional in British English.
- -ize endings were popularized in American English by lexicographers like Noah Webster in the 19th century.
So, both spellings are correct—they just follow different regional conventions.
British English vs American English Spelling

| Common usage | UK, Australia, Canada, India | USA | She apologised / She apologized |

Key Point: The meaning does not change, only the spelling.
