Why People Confuse It

The difference follows a common British-American spelling pattern:

For example:

- offence → offense
- pretence → pretense
This distinction becomes especially noticeable when writing about the military, sports, law, or personal protection.

It means protection against an attack, threat, criticism, or opposing action.
Examples

Mistake 1: Thinking they have different meanings
They do not have different meanings. The difference is primarily regional spelling.
Mistake 2: Mixing spelling systems
Avoid switching randomly between British and American spelling.
For example, using colour but defense is not necessarily grammatically wrong, but it creates an inconsistent spelling style if you intend to use British English throughout.
Mistake 3: Changing every related word
Not every word containing defen- changes between British and American English.
For example, defensive and defender are spelled the same in both varieties.
Mistake 4: Assuming one spelling is incorrect
Neither defence nor defense is a spelling mistake. The appropriate spelling depends on the English variety being used.
Memory Trick
A simple way to remember the difference is:
C = Commonwealth → defence
S = States → defense
Think of defenCE as the spelling associated with British/Commonwealth English and defenSE as the spelling associated with American English.
Another useful pair is:
- British: offence
- American: offense
The same spelling pattern can help you remember defence/defense.
