Why Are There Two Spellings?
The difference reflects the development of American and British spelling conventions. Noah Webster, an American lexicographer, helped promote spelling forms that differed from traditional British usage.
Many American words use -se where British English uses -ce in certain nouns. Examples include defense and defence, offense and offence, and license and licence.
These differences developed through historical spelling preferences and later dictionary and publishing conventions. Neither form is a modern misspelling.

In academic writing, follow your institution’s instructions. In business writing, follow your organization’s style guide. For websites, select the spelling that matches your target market and use it consistently across related pages.

Common Mistakes to Avoid
Treating One Spelling as Incorrect
Both defense and defence are accepted spellings. The correct choice depends on regional conventions.
Mixing American and British English
Using defense in one paragraph and defence in another can make an article look inconsistent. Choose a style before writing.
Changing Related Words Incorrectly
The spelling difference does not apply to every related word in the same way. Both varieties use defend and defensive.
Assuming Pronunciation Changes
The two spellings generally have the same pronunciation. The difference is written, not spoken.
Ignoring the Audience
A US publication generally expects defense, while a UK publication generally expects defence. Follow the readers’ regional conventions.
Easy Memory Trick
Remember this simple rule:
- Defense ends in S for the States. Use it for American English.
- Defence with C follows British conventions. Use it for British English and many other varieties that follow its spelling traditions.
This trick can also help you remember the difference between offense and offence.
