Defences or Defenses – Quick Answer
The quick answer is simple:
- Defences is the correct spelling in British English.
- Defenses is the correct spelling in American English.
Both words mean the same thing.
Examples
British English:
- The country’s military defences were strengthened.

American English:
- The country’s military defenses were strengthened.
- The lawyer prepared several defenses for the case.
The only difference is the spelling.
The Origin of Defences or Defenses
The word comes from the Latin word defendere, which means “to ward off” or “to protect.”
Over time, the word entered Old French and later became part of the English language. As English evolved, spelling differences developed between regions.
When American English became more standardized during the 18th and 19th centuries, many spellings were simplified. One common change was replacing -ce endings with -se endings in certain nouns.
This is why:
- British English kept defence
- American English adopted defense
The same pattern appears in several other words.
