The Origin of Defense or Defence
The word comes from the Latin word defensa, meaning protection.
Later, it moved into Old French as defense. From there, it entered Middle English. At that time, spelling was not fixed, so both versions existed.
Why two spellings?
In the 1800s, spelling reforms began:
- British English kept traditional forms like defence
- American English simplified spellings to defense
This change was influenced by language reformers who wanted simpler spelling in the U.S.
👉 That’s why today we have defense or defence—same meaning, different styles.
