The Origin of Defense and Defence

The word comes from the Latin defensa, meaning protection. It entered English through Old French.

In early English, both “-ce” and “-se” endings were used. Over time:

• British English kept the -ce form in many nouns.
• American English simplified some spellings to -se.

This pattern appears in other words too:

• Licence (UK) / License (US)
• Practice (UK noun) / Practice (US noun)
• Offence (UK) / Offense (US)

So the difference is part of a larger spelling pattern between British and American English.
