If you’ve searched for emphasise or emphasize, you’re not alone. This spelling confusion affects students, writers, bloggers, and professionals every day.
Both spellings look correct. Both appear in books and articles. Even spellcheck accepts them. So why the confusion?

Emphasise or Emphasize – Quick Answer
Both emphasise and emphasize are correct.
The difference depends on regional spelling.
- Emphasise → British English
- Emphasize → American English
Examples
- UK style: The teacher wants to emphasise the importance of reading.

The Origin of Emphasise or Emphasize
The word comes from the Greek word emphainein, meaning “to show” or “to make clear.” It entered English through Latin and French.
In early English, spelling was not fixed. Writers used different endings freely. Over time, English split into regional standards.
Why the spelling changed
- British English kept the -ise ending
- American English adopted the -ize ending
This change was strongly influenced by Noah Webster, who wanted simpler, more consistent American spellings in the 1800s.
That is why we see:
- emphasise / emphasize
- organise / organize
- realise / realize
Both spellings are correct because both evolved naturally.
British English vs American English Spelling
